RA i ORA8835Dot MatrixLCD ControllerSpecificationVersion 1.2June 1, 2005RA i O Technology Inc.©Copyright RAiO Technology Inc. 2004, 20051. OverviewThe RA8835 is a controller IC that can display text and graphics on LCD panel. It can display layered text and graphics, scroll the display in any direction and partition the display into multiple screens. It also stores text, character codes and bitmapped graphics data in external frame buffer memory. Display controller functions include transferring data from the controlling microprocessor to the buffer memory, reading memory data, converting data to display pixels and generating timing signals for the buffer memory, LCD panel.The RA8835 has an internal character generator with 160, 5 X 7 pixel characters in internal mask ROM. The character generators support up to 64, 8 X 16 pixel characters in external character generator RAM and up to 256, 8 X 16 pixel characters in external character generator ROM.2.

Pin Descriptions5.1.1. MCU Interface5.1.2 Display Memory ControlThe RA8835 series can directly access static RAM and PROM. The designer may use a mixture of these two types of memory to achieve an optimum trade-off between low cost and low power consumption.5.1.3 LCD Drive SignalsIn order to provide effective low-power drive for LCD matrixes, the RA8835 series can directly control both the X- and Y-drivers using an enable chain.Pin Name FunctionXD0 to XD3 Data Output for Driver.4-bit X-driver (column drive) data outputs. Connect these outputs to the inputs of the X-driver chips.XSCL Latch Clock.The falling edge of XSCL latches the data on XD0 to XD3 into the input shift registers of the X-drivers. To conserve power, this clock halts between LP and the start of the following display line (See section 6.3.7).XECL Trigger Clock for Chain Cascade.The falling edge of XECL triggers the enable chain cascade for the X-drivers. Every 16th clock pulse is output to the next X-driver.LP Latch Pulse.LP latches the signal in the X-driver shift registers into the output data latches. LP is a falling-edge triggered signal, and pulses once every display line. Connect LP to the Y-driver shift clock on modules.WF AC Drive Output.The WF period is selected to be one of two values with SYSTEM SET command.YSCL Latch Clock for YD.The falling edge of YSCL latches the data on YD into the input shift registers of the Y-drivers. YSCL is not used with driver ICs which use LP as the Y-driver shift clock.YD Data Pulse Output for Y Drivers.It is active during the last line of each frame, and is shifted through the Y drivers one by one (by YSCL), to scan the display’s common connections.YDIS Power-down Output Signal.YDIS is HIGH while the display drive outputs are active. YDIS goes LOW one or two frames after the sleep command is written to the RA8835 series. All Y-driver outputs are forced to an intermediate level (de-selecting the display segments) to blank the display. In order to implement power-down operation in the LCD unit, the LCD power drive supplies must also be disabled when the display is disabled by YDIS.5.1.4. Oscillator and PowerPin Name FunctionXG Crystal Connection for Internal OscillatorThis pin can be driven by an external clock source that satisfies the timing specifications of the EXT f0 signal (See section 7.3.6).XD Crystal Connection for Internal OscillatorLeave this pin open when using an external clock source.VDD 2.7 to 5.5V Supply.This may be the same supply as the controlling microprocessor.GNDGround TESTTest Pin.This is a test pins. No need for connection(NC).Note: The peak supply current drawn by the RA8835 series may be up to ten times the averagesupply current. The power supply impedance must be kept as low as possible by ensuring that supply lines are sufficiently wide and by placing 0.47μF decoupling capacitors that have good high-frequency response near the device’s supply pins.6.

第3章RA8875屏触摸校准自适应
第3章RA8875屏触摸校准自适应将本期教程放在第三章主要是方便开发板用户可以直接运行后面章节中的例子，而不用每次执行例子前都做一次触摸的校准，本期教程提供的方法可以将触摸参数保存到EEPROM里面，以后使用只需从EEPROM加载这个参数即可。
本期教程提供的校准方法可以自适应安富莱生产的RA8875 -4.3寸，5寸和7寸屏。
3.1 触摸校准基础知识介绍3.2 触摸屏校准步骤3.3 触摸参数自动加载3.4总结3.1触摸校准基础知识介绍这部分基础的知识大家有个了解即可，不了解也没有关系，通过后面几期简单的学习后，会抽出一章专门的讲解触摸校准方面的知识。
1.STemWin自带的触摸校准函数在X轴镜像，Y轴镜像或者都镜像的情况下依然可以正常使用。
认识到这点非常的关键，要不搞着搞着就把自己绕进去了。
2.大家拿到LCD屏以后，要显示图片、文字等的时候，不外乎横屏或者竖屏显示，一旦显示方式确定了，那么屏的扫描方式也就确定了（啥是扫描方式，也是就是X,Y轴坐标地址的递增方向）。
扫描方式确定下来以后，后面所有的操作都要以这个为参照对象，咱们前面说的X轴镜像，Y轴镜像就是以这个为参照对象的。
3.STemWin自带的触摸函数是校准不了X,Y轴翻转的，这个大家一定要认识到，咱们主要解决的也就是X,Y翻转。
4.STemWin底层在获取X,Y轴ADC数值的时候，只要保证：int GUI_TOUCH_X_MeasureX(void) //这里用于获取X轴ADC的数值int GUI_TOUCH_X_MeasureY(void) //这里用于获取Y轴ADC的数值底层保证读取位置一致，需要做修改的话都放在应用层。
5.学习一下官方的GUI_TOUCH_SetOrientation函数。
6.校准好参数以后将结果保存到EEPROM里面，以后开机直接加载即可。
3.2触摸屏校准步骤3.2.1第一步：下载触摸自适应校准程序到开发板这个工程代码是裸机的STemWin5.22，工程文件如下：3.2.2第二步：进行触摸校准将程序下载到板子里面之后，显示效果如下：先点击左上角的小圆圈（最好找个触摸笔点击，这样比较准确），点击后效果如下：然后在点击右下角的小圆圈，点击后效果如下：进入到这步以后表示触摸校准已经成功，并且触摸参数已经保存到了EEPROM里面，用户可以在这个界面上实现简单的绘图功能，观察触摸是否准确，如果不准确请重新启动板子，再次进行校准。

This sensor from Panasonic is an 8x8 array of IR thermal sensors. When connected to your microcontroller (or raspberry Pi) it will return an array of 64 individual infrared temperature readings over I2C. It's like those fancy thermal cameras, but compact and simple enough for easy integration.This part will measure temperatures ranging from 0°C to 80°C (32°F to 176°F) with an accuracy of +- 2.5°C (4.5°F). It can detect a human from a distance of up to 7 meters (23) feet. With a maximum frame rate of 10Hz, It's perfect for creating your own human detector or mini thermal camera. We have code for using this breakout on an Arduino or compatible (the sensor communicates over I2C) or on a Raspberry Pi with Python. On the Pi, with a bit of image processing help from the SciPy python library we were able to interpolate the 8x8 grid and get some pretty nice results!The AMG8833 is the next generation of 8x8 thermal IR sensors from Panasonic, and offers higher performance than it's predecessor the AMG8831. The sensor only supports I2C, and has a configurable interrupt pin that can fire when any individual pixel goes above or below a thresholds that you set.To make it easy to use, we pick & placed it on a breakout board with a 3.3V regulator and level shifting. So you can use it with any 3V or 5V microcontroller or computer.Even better - We've done all the hard work here, with example code and supporting software libraries to get you up inrunning in just a few lines of code!PinoutsThis camera has 4 mounting holes, and two header strips. Only the bottom strip is connected to the sensor. The top set of breakouts is there for mechanical stability only!The 6 holes at the top of the board are provided for stability and are not connected to anything. Use these if you wantyour sensor to sit nice and flat on a breadboard or Perma-Proto.AssemblyPrepare the header strips:Cut the strips to length if necessary. It will be easier tosolder if you insert it into a breadboard - long pins downAdd the breakout board:Place the breakout board over the pins so that the shortpins poke through the breakout padsAnd Solder!Be sure to solder all pins for reliable electrical contact. (For tips on soldering, be sure to check out our Guide to Excellent Soldering (https://adafru.it/aTk)).You're done! Check your solder joints visually and Arraycontinue onto the next stepsYou can easily wire this breakout to any microcontroller, we'll be using an Arduino. You can use any other kind of Download Adafruit_AMG88xx libraryTo begin reading sensor data, you will need to install the Adafruit_AMG88xx library (https://adafru.it/xfw).Start up the IDE and open the Library Manager:Type in AMG88xx until you see the Adafruit Library pop up. Click Install!We also have a great tutorial on Arduino library installation at:/adafruit-all-about-arduino-libraries-install-use (https://adafru.it/aYM)Load Thermistor TestOpen up File->Examples->Adafruit_AMG88xx->amg88xx_test and upload to your Arduino wired up to the sensor. This example just connects to the sensor and reads the internal thermistor to test your connections.Once uploaded to your Arduino, open up the serial console at 9600 baud speed to see the internal thermistor reading. If you get a reading of ~26° degrees (room temperature) then everything is wired and working correctly!Pixel Array OutputOK now that we know the sensor is working, let's read actual thermal data. Load up File -> Examples ->Adafruit_AMG88 -> pixels_testUpload the code, and open the serial console at 9600 baud rate. You should see a printout of the array of readings every second. Each number is the detected temperature in Celsius, and in the 8x8 grid order that comes from the sensorThe numbers should increase if you put your hand or face above the sensor. They'll decrease if you hold up something cold in front of the sensor eyeLibrary ReferenceTo create the object, useInitialize the sensor usingto read the pixels you will need an array to place the readings into. Once you have one, you can call readPixels. Make sure the array you create is big enough by using the pre-defined AMG88xx_PIXEL_ARRAY_SIZE macro.Adafruit_AMG88xx amg;status = amg.begin();if (!status) {Serial.println("Could not find a valid AMG88xx sensor, check wiring!");while (1);}float pixels[AMG88xx_PIXEL_ARRAY_SIZE];amg.readPixels(pixels);Arduino Library DocsArduino Library Docs (https://adafru.it/Au6)Arduino Thermal CameraTo make your Arduino into a cool thermal camera, we can add a small display.In this example we use an Adafruit 1.44" Color TFT. With some code changes, you can use other size displays but a color display is best of course.Keep your AMG8833 breakout wired as you already have it from the Wiring & Test section above, and add your TFT like thisOnce everything is all wired up, load up File->Examples->Adafruit_AMG88xx->thermal_camHit upload and you should have a simple thermal camera!Adafruit 1.44" Color TFT LCD Display with MicroSD Card breakout$14.95IN STOCKADD TO CARTJames DV has also sent over a version that is optimized if you want a faster display-update rate(https://adafru.it/BPj)Adafruit CircuitPythonPython Computer WiringSince there's dozens of Linux computers/boards you can use we will show wiring for Raspberry Pi. For other platforms, please visit the guide for CircuitPython on Linux to see whether your platform is supportedCircuitPython Installation of AMG88xx LibraryYou'll need to install the Adafruit CircuitPython AMG88xxFirst make sure you are running theThat's all there is to using AMG88ss with CircuitPython!

By adding processing power, you can 'turn' the 8x8 output into what appears to be a higher-resolution display.We're using a PiTFT 2.8" and a Pi Cobbler but the code can be adapted to output to the HDMI display - we're using pygame to draw to the framebuffer.You can use any Raspberry Pi computer, from Pi A+ to Pi 3 or even a Pi Zero, but we happen to have a Pi 3 on our desk set up already so we're using that.Raspberry Pi 3 - Model B - ARMv8 with 1G RAM$35.00IN STOCKADD TO CARTSetup PiTFTIf you have not done so already, the first thing you will need to do is setup your PiTFT. Instructions on how to do so can be found in this guide (https://adafru.it/sha).Install Python SoftwareOnce your PiTFT is all set up, and you have Internet access set upfor the AMG8833 so you can read data from the sensor.Finally, install both pygame and scipy. Pygame lets us draw easily to a screen using python, we'll use that to make the display work. Scipy is a powerful scientific/data processing library that we can use to magically turn the 8x8 = 64 pixel array into something that looks more like a 32x32 = 1024 pixel array. Wow, isn't digital signal processing cool?You can also use direct wires, we happen to have a Cobbler ready. remember you can plug the cobbler into the bottom of the PiTFT to get access to all the pins!Now you should be able to verify that the sensor is wired up correctly by asking the Pi to detect what addresses it can see on the I2C bus:It should show up under it's default address (0x69). If you don't see 0x69, check your wiring, did you install I2Csudo i2cdetect -y 1support, etc?Run example codeAt long last, we are finally ready to run our example code"""This example is for Raspberry Pi (Linux) only!It will not work on microcontrollers running CircuitPython!"""import osimport mathimport timeimport busioimport boardimport numpy as npimport pygamefrom scipy.interpolate import griddatafrom colour import Colorimport adafruit_amg88xxi2c_bus = busio.I2C(board.SCL, board.SDA)#low range of the sensor (this will be blue on the screen)MINTEMP = 26.#high range of the sensor (this will be red on the screen)MAXTEMP = 32.#how many color values we can haveCOLORDEPTH = 1024os.putenv('SDL_FBDEV', '/dev/fb1')pygame.init()#initialize the sensorsensor = adafruit_amg88xx.AMG88XX(i2c_bus)# pylint: disable=invalid-slice-indexpoints = [(math.floor(ix / 8), (ix % 8)) for ix in range(0, 64)]grid_x, grid_y = np.mgrid[0:7:32j, 0:7:32j]# pylint: enable=invalid-slice-index#sensor is an 8x8 grid so lets do a squareheight = 240width = 240#the list of colors we can choose fromblue = Color("indigo")colors = list(blue.range_to(Color("red"), COLORDEPTH))#create the array of colorscolors = [(int(c.red * 255), int(c.green * 255), int(c.blue * 255)) for c in colors]displayPixelWidth = width / 30displayPixelHeight = height / 30If you have everything installed and wired up correctly, you should see a nice thermal camera image.

本设计主要介绍了一个基于RA8835的液晶屏驱动程序的设计，该功能由C8051F020单片机和RA8835液晶驱动芯片两个核心器件来实现，C8051F020控制RA8835来完成液晶显示功能。
软件部分用C语言来编写，详细介绍了基于单片机C8051F020的应用软件设计。
本设计是在原有的硬件平台的基础上根据液晶屏的基本驱动指令给出了各个模块的驱动程序设计，如任意位置打点、画线、画圆、任意位置字符、字符串、汉字的显示，并且分析了最基础的功能模块——打点的算法原理。
作为打点功能的延伸，编写了一个支持图片显示的程序。
作为显示汉字功能的延伸，编写了一个支持任意大小汉字显示的程序。
最后，把以上各个功能模块综合起来显示，也完成了一个简单信息界面的显示。
实验证明这是一种简单但有效的工作方案,对此进行少量修改就可用于很多不同场合,实用性强。

调试笔记
师兄第一板仿真器连接出现如下问题
然后新板连接出现如下问题
又Hale Waihona Puke 现：7.9号上午SDRAM读写正常，再次连接仿真器出现如下错误：
不知道是什么原因造成的，晶振也莫名的不起振了，折腾了半天，最后将万用表调到短路档，黑笔接地，红笔把DSP背面的滤波电容全部放电。上电后晶振起振了，仿真器连接成功，并且可以Download程序并运行，写SDRAM结果正确。
SDRAM调试结果如下：程序功能为向SDRAM中写入100个字，地址范围600002~600066，写入数据分别为1~100
液晶模块 RA8835中文操作资料
RA8835能够同时管理三到四个显示区。每个显示区都拥有自己的的显示 特性。这里将四个区定义为第一显示区L1、第二显示区L2、第三
显示区L3、第四显示区L4。RA8835以第一和第二显示区为主显示区，第三第四 显示区为辅显示区。在控制单屏结构液晶显示驱动系统时，RA8835可以分别或 同时使用第一、第二和第三显示区。在控制双屏液晶显示驱动系统时，RA8835 需要组合使用所有四个显示区。在这种情况下，第一、第二仅管理显示屏上半 屏的显示数据，第三、第四显示区管理显示屏的下半屏的显示数据，并规定第 一和第三显示区合成为一控制全屏显示，第二和第四合成为一控制全屏显示。

或者，MCU interface 的cable儘量勿長於30公分。
Ans. 1: LCM display system ordinary have a bus line configuration on printed circuit boards for data communication between MCU and RA8835. To avoid the display/ the access error, we suggest that bus signals might be better stabilized by pulling up to VCC using the resistors around 1k-3.3 k or keeping the length of MCU interface less then 30CM.請參考下列相關圖示說明：Please refer to the following picture.Figure 1 Pull-up resisterFigure 2 MCU interface wire length問題二.
