Design and Implementation of Continuous Measuring Temperature Monitor
WU Di，ZHAO Zhuo，CHEN Feng
（Weihai Wego Medical Imaging Technology Co.，Ltd.，Weihai 264210，China） Abstract：Aiming at the disadvantages of current high precision continuous temperature measuring equipment，such as single variety，high cost and complex operation，the design scheme based on thermal resistor and single chip micro鄄 computer is proposed. Using STM32L152 as main control chip，sampling，calibrating and amplification function modules are designed. Through the continuous sampling and real鄄time calibration，high precision continuous temperature mea鄄 surement is realized. Long time continuous work is achieved by low power system design and use of large capacity battery. The hardware design scheme and software design flow of each module are introduced in detail. The experi鄄 mental test and practical application show that the system has stable performance and high measurement accuracy. The maximum error is 0.1 ℃ within the specified measurement range，which meets the design standard. The average continuous working time is 273 h，which can meet the requirements of practical applications. Key words：temperature monitor；STM32；high accuracy；continuous measuring
树莓派OLED模块的使用教程大量例程详解
树莓派OLED模块的使⽤教程⼤量例程详解简介Python有两个可以⽤的OLED库[Adafruit_Python_SSD1306库]—>只⽀持SSD1306[Luma.oled库]—>⽀持SSD1306 / SSD1309 / SSD1322 / SSD1325 / SSD1327 / SSD1331 / SSD1351 / SSD1362 / SH1106 / WS0010驱动芯⽚通过本篇教程，你可以学习树莓派环境下I2C接⼝OLED基础功能的使⽤，以及获取到复杂功能的Demo例程。
故事背景时常有看到⽹络上有⼀些OLED做的智能⼩时钟，⾮常漂亮，OLED作为⼀款⾃发光、低功耗、低成本的屏幕，⾮常受⼤家的喜爱，因此我也⽐较好奇，研究了⼀下OLED的使⽤，说⼲就⼲，那我们就开始吧！硬件准备HDMI显⽰屏（推荐直接使⽤VNC或SSH⼯具远程登录，则可以少准备⼀个显⽰屏）（有线也可以，远程访问则可以不⽤）路由器Windows主机给今天的主⾓OLED亮个像吧：软件准备1. 启动树莓派I2C功能2. OLED的驱动库的选择Python有两个可以⽤的OLED库[Adafruit_Python_SSD1306库]—>只⽀持SSD1306[Luma.oled库]—>⽀持SSD1306 / SSD1309 / SSD1322 / SSD1325 / SSD1327 / SSD1331 / SSD1351 / SSD1362 / SH1106 / WS0010驱动芯⽚在这⾥我们应该怎么选择呢？先说结论：我⽐较推荐Luma.oled这个库。
下⾯分析对⽐⼀下两个库的优缺点：库优点缺点Adafruit上⼿简单例程少，功能弱，只⽀持⼀种芯⽚Luma.oled例程丰富，功能强⼤，⽀持芯⽚丰富上⼿难度稍⼤这⾥顺便贴出Luma和Adafruit库的链接：Luma官⽅⽰例代码截图⽰例代码⽬录如下从⽰例代码截图也可以看到Adafruit的例程确实很少3. Luma.oled驱动库的安装Luma.oled是基于 Python 的OLED 库，所以要⽤pip来安装，现在⽐较流⾏python3，所以推荐⽤pip3，输⼊指令sudo pip3 install luma.oledpython2 安装只需要将pip3换成pip即可Adafruit的安装指令为：sudo pip3 install Adafruit-SSD1306[外链图⽚转存失败,源站可能有防盗链机制,建议将图⽚保存下来直接上传(img-7p3KdxSL-1631859093083)(index_files/04ecc9f6-9e43-4abc-a966-78822de0a1e4.png)]如果安装失败，注意检查pip⼯具是否需要更新，注意检查⽹络是否通畅硬件连接1. 参考树莓派引脚图这个图⽐较详细，也⽐较复杂了，我们暂时只需要关注表格中间功能名，物理引脚，功能名这三列，找到1--3.3v，3--SDA.1，5--SCL.1，6--GND这四个引脚2. 参考OLED模块的引脚图引脚编号功能功能说明1GND电源地线，电源负极2VCC电源正极，⼤部分OLED模块3.3v即可驱动3SCL I2C时钟线4SDA I2C数据线3. 使⽤双母头杜邦线按照上述引脚图Pin-to-Pin连接即可，连接好后树莓派的引脚分布为L形状，接线⽰意图如下千万注意电源正负极别接反了，容易烧板⼦知识储备以下知识不在本教程详细讨论范围，但还是列举出来，有兴趣的可以⽹上找找资料深⼊学习1. OLED显⽰原理，驱动原理（嵌⼊式内容），推荐这篇博客进⾏了解2. I2C通信原理，I2C总线特点例程⼀：使⽤OLED显⽰“Hello，World”编代码先从Hello，World开始，有了⼀，就有了⽆限可能，步骤如下：1. 根据前⽂的步骤连接好OLED模块，查找oled的I2C地址，每个OLED模块的I2C地址不⼀定都相同，需要先查找获取地址，同时也检查⼀下OLED模块是否连接正常。

升压过程中的过压保护 OVP 内置的比较器阈值为 1.05V，升压值通过电阻串分压后输入 OVP 进行检测比较，高于 该值则停止关闭功率 MOS 等待输出电压自然回落。 正常工作时，OVP 的采样值需要小于 1.05V，一般设计时可以参考 LED 灯串电压溢出 10%
电源抗干扰 为保证大功率使用下的稳定，芯片电源输入的 VCC 管脚，推荐采用 10 ~200Ω的电阻来与 升压电源隔离。

DF6113 的升压控制机理 利用电感线圈，通过 BOOST 方式的 DC/DC 升压来提供灯能量，依靠升压后的稳压电容来 抑制灯电流纹波。正常情况下，功率 MOS 和肖特基二极管的品质决定升压效率。推荐的 DC/DC 升压比小于 1:5
升压元器件的选择
对应 300KHZ 频率，升压电感通常 47~100u； MOS 源端串联到地的电阻 RMOS，其大小决定了输出功率，对应 10W 输出的应用，参考选用 0.3Ω电阻。

OLED屏的驱动及使用
OLED屏的驱动与使用文/杜洋【OLED时代来了】一提到OLED，我想无人不知。
智能手机的迅猛发展，使得屏幕显示技术不断推陈出新。
虽然最新报出三星将产量更新颖的QLED屏幕，但在没有上市之前智能手机屏幕从显示原理上仍只有LCD和OLED两种。
在三星和LG两家公司的高端手机上都采用了OLED屏幕，其他手机生产商还是采用传统的LCD屏幕。
其两者最大的区别就是：LCD屏幕是由灯管或LED做背光照明，再通过LCD屏通过或阻断光线达到显示目的。
OLED是有机发光二极管，它和我们常用的LED 是近亲。
OLED不需要背光灯，其上面每一个像素点都能独立发光。
综合来看OLED显示技术功耗更低、效果更有优势。
我曾用过一款手机，采用的是SUPER OLED屏幕，无论从色彩还是可视角度都非常出众。
不过现在仅有几家大公司才能生产OLED屏幕，产量不足，价格昂贵。
OLED屏供应手机市场都不足够，作为一名电子爱好者更不敢奢求有一天能亲手把玩它了。
记得3年前，我在北京工作的时候，就曾在电子市场看到久闻未见的OLED屏幕。
之所以让我一眼就识别出来，是因那柜台里每一块屏幕都只是一片薄薄的玻璃，发着光的文字和图案在上面不停切换，周围没有背光灯，没有电路板，只有一片玻璃。
旁人也许并无感想，但对我这个电子发烧友来说，这种震撼不亚于第一次看到没有“大包”的液晶电视。
站在柜台前看了半天，老板见势走过来。
我指着那片1元硬币大小的屏幕问多少钱，老板一本正经地说：“这款小的便宜，你要多少？”我说只要1个。
他有些不太高兴的说：“一个呀，280元”。
听闻此言，二话没说，转身就跑。
只是一块单色的小屏幕，如果是LCD液晶屏顶多80元，就因为是OLED就多出200元。
可是又忍不住对它的神奇所吸引，好想能早点把玩。
时间是把无情刀，能杀人，也能杀价。
如今的OLED技术已经广泛被使用，产量高了，价格自然就降低了。
从前上百元的OLED屏幕，现在只要几十元。
还有各种尺寸大小、颜色和分辨率。

Interface can be selected by different selections of IM0~2 as shown in Table 1.Note1: When Serial Interface (SPI) or I2C Interface is selected, D7~D2 is Hz. D7~ D2 is recommended toconnect the V DD1 or V SS. It is also allowed to leave D7~ D2 unconnected.6800-series Parallel InterfaceThe parallel interface consists of 8 bi-directional data pads (D7-D0), WR(WR/) =R/), RD(E), A0 and CS. When WR(W “H”, read operation from the display RAM or the status register occurs. When WR(WR/) = “L”, Write operation to display data RAM or internal command registers occurs, depending on the status of A0 input. The RD (E) input serves as data latch signal (clock) when it is “H”, provided that CS = “L” as shown in Table. 2.internally performed, which require the insertion of a dummy read before the first actual display data read. This is shown in Figure. 1 below.SH1106Data Read address n Dummy readSet address n Data Read address n+1Figure. 18080-series Parallel InterfaceThe parallel interface consists of 8 bi-directional data pads (D7-D0), WR (W R /), RD (E), A0 and CS . The RD (E) inputserves as data read latch signal (clock) when it is “L” provided that CS = “L”. Display data or status register read is controlled by A0 signal. The WR (W R /) input serves as data write latch signal (clock) when it is “L” and provided that CS = “L”. Display data or command register write is controlled by A0 as shown in Table. 3.Table. 3Data Bus SignalsThe SH1106 identifies the data bus signal according to A0, RD (E) and WR (W R /) signals.Table. 4SH11064 Wire Serial Interface (4-wire SPI)The serial interface consists of serial clock SCL, serial data SI, A0 and CS . SI is shifted into an 8-bit shift register on every rising edge of SCL in the order of D7, D6, … and D0. A0 is sampled on every eighth clock and the data byte in the shift register is written to the display data RAM (A0=1) or command register (A0=0) in the same clock. See Figure. 2.Table. 5DD1SS D7~ D2 unconnected.The serial interface is initialized when CS is high. In this state, SCL clock pulse or SDI data have no effect. A falling edge on CS enables the serial interface and indicates the start of data transmission. The SPI is also able to work properly when the CS always keep low, but it is not recommended.SI (D1)CS D7D6D5D4D3D2D1D0D7D6D5A0SCL(D0)Figure. 2 4-wire SPI data transferl When the chip is not active, the shift registers and the counter are reset to their initial statuses. l Read is not possible while in serial interface mode.l Caution is required on the SCL signal when it comes to line-end reflections and external noise.

SI is shifted into an 9-bit shift register on every rising edge of SCL in the order of C D /, D7, D6, … and D0. The C D / bit (first of the 9 bit) will determine the transferred data is written to the display data RAM (C D /=1) or command register (C D /=0).Table. 6DD1SS D7~ D2 unconnected.The serial interface is initialized when CS is high.

The command or RAM data can be written into the chip and the status and RAM data can be read out of the chip.DD1SS D7~ D2 unconnected.CS signal could always pull low in I 2C-bus application. Characteristics of the I 2C-busThe I 2C-bus is for bi-directional, two-line communication between different ICs or modules. The two lines are a serial data line (SDA) and a serial clock line (SCL). Both lines must be connected to a positive supply via a pull-up resistor. Data transfer may be initiated only when the bus is not busy.Note: The positive supply of pull-up resistor must equal to the value of V DD1.SH1106 Bit TransferOne data bit is transferred during each clock pulse. The data on the SDA line must remain stable during the HIGH period of the clock pulse as changes in the data line at this time will be interpreted as a control signal.SDASCLData line stable: Data valid Change data allowedFigure. 3 Bit TransferStart and Stop conditionsBoth data and clock lines remain HIGH when the bus is not busy. A HIGH-to-LOW transition of the data line, while the clock is HIGH is defined as the START condition (S). A LOW-to-HIGH transition of the data line while the clock is HIGH is defined as the STOP condition (P).SDASCLSDASCLSTART condition STOP conditionS PFigure. 4 Start and Stop conditionsSystem configurationl Transmitter: The device that sends the data to the bus.l Receiver: The device that receives the data from the bus.l Master: The device that initiates a transfer, generates clock signals and terminates a transfer.l Slave: The device addressed by a master.l Multi-Master: More than one master can attempt to control the bus at the same time without corrupting the messagel Arbitration: Procedure to ensure that, if more than one master simultaneously tries to control the bus, only one is allowed to do so and the message is not corrupted.l Synchronization: Procedure to synchronize the clock signals of two or more devices.Figure. 5 System configurationSH1106Acknowledge Each byte of eight bits is followed by an acknowledge bit. The acknowledge bit is a HIGH signal put on the bus by the transmitter during which time the master generates an extra acknowledge related clock pulse. A slave receiver which is addressed must generate an acknowledge after the reception of each byte. Also a master receiver must generate an acknowledge after the reception of each byte that has been clocked out of the slave transmitter. The device that acknowledges must pull-down the SDA line during the acknowledge clock pulse, so that the SDA line is stable LOW during the HIGH period of the acknowledge related clock pulse (set-up and hold times must be taken into consideration). A master receiver must signal an end of data to the transmitter by not generating an acknowledge on the last byte that has been clocked out of the slave. In this event the transmitter must leave the data line HIGH to enable the master to generate a stop condition.clock pulse for acknowledgementDATA OUTPUT BYTRANSMITTERDATA OUTPUT BYRECEIVERSCL FROM MASTERFigure 6 AcknowledgeProtocolThe SH1106 supports both read and write access. The W R/ bit is part of the slave address. Before any data is transmitted onthe I 2C-bus, the device that should respond is addressed first. Two 7-bit slave addresses (0111100 and 0111101) are reserved for the SH1106. The least significant bit of the slave address is set by connecting the input SA0 to either logic 0(VSS) or 1(VDD1). The I 2C-bus protocol is illustrated in Fig.7. The sequence is initiated with a START condition (S) from the I 2C-bus master that is followed by the slave address. All slaves with the corresponding address acknowledge in parallel, all the otherswill ignore the I 2C-bus transfer. After acknowledgement, one or more command words follow which define the status of the addressed slaves. A command word consists of a control byte, which defines Co and C D /(note1), plus a data byte (see Fig.7). The last control byte is tagged with a cleared most significant bit, the continuation bit Co. After a control byte with a cleared Co-bit, only data bytes will follow. The state of the C D /-bit defines whether the data-byte is interpreted as a command or as RAM-data. The control and data bytes are also acknowledged by all addressed slaves on the bus. After the last control byte, depending on the C D / bit setting, either a series of display data bytes or command data bytes may follow. If the C D / bit was set to ‘1’, these display bytes are stored in the display RAM at the address specified by the data pointer. The data pointer is automatically updated and the data is directed to the intended SH1106 device. If the C D / bit of the last control byte was set to ‘0’, these command bytes will be decoded and the setting of the device will be changed according to the received commands.The acknowledgement after each byte is made only by the addressed slave. At the end of the transmission the I 2C-bus master issues a stop condition (P). If the W R/ bit is set to one in the slave-address, the chip will output data immediately after the slave-address according to the C D / bit, which was sent during the last write access. If no acknowledge is generated by the master after a byte, the driver stops transferring data to the master.SH1106Control ByteS - start condition P - stop condition A - Acknowledge A - Not Acknowledge M - I 2C master S' - I 2C slaveFigure 7 I 2C ProtocolNote1:1. Co ＝“0”: The last control byte , only data bytes to follow,Co ＝“1”: Next two bytes are a data byte and another control byte; 2. C D /＝“0”: The data byte is for command operation, C D /＝“1”: The data byte is for RAM operation.Access to Display Data RAM and Internal RegistersThis module determines whether the input data is interpreted as data or command. When A0 = “H”, the inputs at D7 - D0 are interpreted as data and be written to display RAM. When A0 = “L”, the inputs at D7 - D0 are interpreted as command, they will be decoded and be written to the corresponding command registers. Display Data RAMThe Display Data RAM is a bit mapped static RAM holding the bit pattern to be displayed. The size of the RAM is 132 X 64 bits. For mechanical flexibility, re-mapping on both segment and common outputs can be selected by software.For vertical scrolling of the display, an internal register storing display start line can be set to control the portion of the RAM data to be mapped to the display.SH1106 The Page Address CircuitAs shown in Figure. 8, page address of the display data RAM is specified through the Page Address Set Command. The page address must be specified again when changing pages to perform access.The Column AddressAs shown in Figure. 8, the display data RAM column address is specified by the Column Address Set command. The specified column address is incremented (+1) with each display data read/ write command. This allows the MPU display data to be accessed continuously. Because the column address is independent of the page address, when moving, for example, from page0 column 83H to page 1 column 00H, it is necessary to re-specify both the page address and the column address. Furthermore, as shown in Table. 7, the Column re-mapping (ADC) command (segment driver direction select command) can be used to reverse the relationship between the display data RAM column address and the segment output. Because of this, the constraints on the IC layout when the OLED module is assembled can be minimized.Table. 7Segment Output SEG0 SEG131ADC “0” 0 (H) àColumn Address à 83 (H)ADC “1” 83 (H) ßColumn Address ß 0 (H)The Line Address CircuitThe line address circuit, as shown in Figure. 8, specifies the line address relating to the common output when the contents of the display data RAM are displayed. Using the display start line address set command, what is normally the top line of the display can be specified (this is the COM0 output when the common output mode is normal, and the COM63 output for SH1106, when the common output mode is reversed. The display area is a 64-line area for the SH1106 from the display start line address.If the line addresses are changed dynamically using the display start line address set command, screen scrolling, page swapping, etc. that can be performed relationship between display data RAM and address (if initial display line is 1DH).SH1106Figure. 8This is a RC type oscillator (Figure 9) that produces the display clock. The oscillator circuit is only enabled when CLS = “H”.When CLS = “L”, the oscillation stops and the display clock is inputted through the CL terminal.Figure 9SH1106 Charge Pump RegulatorThis block accompanying only 2 external capacitors, is used to generate a 6.4V~9.0V voltage for OLED panel. This regulator can be turned ON/OFF by software command 8Bh setting.Charge Pump output voltage controlThis block is used to set the voltage value of charger pump output. The driving voltage can be adjusted from 6.4V up to 9.0V. This used to meet different demand of the panel.Current Control and Voltage ControlThis block is used to derive the incoming power sources into different levels of internal use voltage and current. VPP and VDD2 are external power supplies. IREF is a reference current source for segment current drivers.Common Drivers/Segment DriversSegment drivers deliver 132 current sources to drive OLED panel. The driving current can be adjusted up to 200m A with 256 steps. Common drivers generate voltage scanning pulses.Reset CircuitWhen the RES input falls to “L”, these reenter their default state. The default settings are shown below:1. Display is OFF. Common and segment are in high impedance state.2. 132 X 64 Display mode.3.

Internal DC-DC is selected.SH1106 CommandsR/) signals to identify data bus signals. As the chip analyzes and The SH1106 uses a combination of A0, RD(E) and WR(Wexecutes each command using internal timing clock only regardless of external clock, its processing speed is very high and itsbusy check is usually not required. The 8080 series microprocessor interface enters a read status when a low pulse is input to the RD pad and a write status when a low pulse is input to the WR pad. The 6800 series microprocessor interface enters aR/ pad and a write status when a low pulse is input to this pad. When a high read status when a high pulse is input to the Wpulse is input to the E pad, the command is activated. (For timing, see AC Characteristics.). Accordingly, in the command explanation and command table, RD (E) becomes 1(HIGH) when the 6800 series microprocessor interface reads status of display data. This is an only different point from the 8080 series microprocessor interface.Taking the 8080 series, microprocessor interface as an example command will explain below.When the serial interface is selected, input data starting from D7 in sequence.Command Set1. Set Lower Column Address: (00H - 0FH)2. Set Higher Column Address: (10H - 1FH)Specifies column address of display RAM. Divide the column address into 4 higher bits and 4 lower bits. Set each of them intosuccessions. When the microprocessor repeats to access to the display RAM, the column address counter is incrementedduring each access until address 131 is accessed. The page address is not changed during this time.Higher bitsLower bitsA7 A6 A5 A4 A3 A2 A1 A0 Line address0 0 0 0 0 0 0 0 00 0 0 0 0 0 0 1 1: :1 0 0 0 0 0 1 1 131Note: Don’t use any commands not mentioned above.3.

It is followed by the higher number of lines in ascending order, corresponding to the duty cycle. When this command changes the line address, the smooth scrolling or page change takes place.A5 A4 A3 A2 A1 A0 Line address0 0 0 0 0 0 00 0 0 0 0 1 1: :1 1 1 1 1 0 621 1 1 1 1 1 635. Set Contrast Control Register: (Double Bytes Command)This command is to set contrast setting of the display. The chip has 256 contrast steps from 00 to FF. The segment output current increases as the contrast step value increases.Segment output current setting: ISEG = a/256 X IREF X scale factorWhere: a is contrast step; IREF is reference current equals 12.5µA; Scale factor = 16.n The Contrast Control Mode Set: (81H)When this command is input, the contrast data register set command becomes enabled. Once the contrast control mode has been set, no other command except for the contrast data register command can be used. Once the contrast data set command has been used to set data into the register, then the contrast control mode is released.n Contrast Data Register Set: (00H - FFH)By using this command to set eight bits of data to the contrast data register; the OLED segment output assumes one of the 256 current levels.When this command is input, the contrast control mode is released after the contrast data register has been set.。
