I2C 接口定义
总线的构成及信号类型 I2C总线是由数据线SDA和串行时钟线SCL构成的串行总线，可发送和接收数据。在信息的传输过 程中，SC09A是被控器（slaver）,主控MCU是主控器（master）。 SCL是串行时钟线，在通信过程中始终由主控MCU控制； SDA是数据线，接上拉电阻，主控器（master）和被控器（slaver）都可以控制SDA线，它们芯 片内部是open-drain结构（即输出高电平时为上拉电阻或高阻，输出低电平时是强驱动），发送 “0”时通过芯片内部的NMOS将SDA线拉低，发送“1”时释放总线由上拉电阻将SDA线拉到高电 平。在SCL的低电平时改变状态来发送地址、数据和ACK信号，在SCL的高电平时改变状态来发送 开始和结束信号。 开始信号（start）：SCL 为高电平时，SDA 由高电平向低电平跳变，开始传送数据。 结束信号（end）：SCL 为高电平时，SDA 由低电平向高电平跳变，结束传送数据。 应答信号（ACK）：SC09A 在接收到读命令后，如果地址正确，会向主控制器发出低电平脉冲， 表示已收到数据。

Rx channels to enable four touch keys.The touch keys must not share their Tx channel with the touch screen.However,Rx channels have to be shared.2)Touch key design on FPC:Connect one separate Tx channel to four Rx channels to enablefour touch keys.The touch keys have to share their Rx channels with the touch screen.T ouch key pattern on FPC should be designed independently.华信科专用6.I 2C Communication6.1I 2C TimingGT9271provides a standard I2C interface for SCL and SDA to communicate with the host.GT9271always serves as slave device in the system with all communication being initialized by the host.It is strongly recommended that transmission rate be kept at or below 400Kbps.The I2C timing is shown below:Test condition 1:1.8V host interface voltage,400Kbps transmission

hd10.6-us SDA setup time t st20.1-us SDA hold timet hd2-UsGT9271supports two I 2C slave addresses:0xBA/0xBB and 0x28/0x29.The host can select the address by changing the status of Reset and INT pins during the power-on initialization phase.See the diagram below for detailed timings:华信科专用Power-on Timing:Timing for host resetting GT9271:Timing for setting slave address to 0x28/0x29:Timing for setting slave address to 0xBA/0xBB:华信科专用a)Data Transmission(For example ：slave address is 0xBA/0xBB)Communication is always initiated by the host.Valid Start condition is signaled by pulling SDA line from high to low when SCL line is high.Data flow or address is transmitted after the Start condition.All slave devices connected to I 2C bus should detect the 8-bit address issued after Start condition and send the correct ACK.After receiving matching address,GT9271acknowledges by configuring SDA line as output port and pulling SDA line low during the ninth SCL cycle.When receiving unmatched address,namely,not 0XBA or 0XBB,GT9271will stay in an idle state.For data bytes on SDA,each of 9serial bits will be sent on nine SCL cycles.Each data byte consists of 8valid data bits and one ACK or NACK bit sent by the recipient.The data transmission is valid when SCL line is high.When communication is completed,the host will issue the Stop condition which implies the transition of SDA line from low to high when SCL line is high.b)Writing Data to GT9271(For example ：slave address is 0xBA/0xBB)Timing for Write OperationThe diagram above displays the timing sequence of the host writing data onto GT9271.First,the host issues a Start condition.Then,the host sends 0XBA (address bits and R/W bit;R/W bit as 0indicates Write operation)to the slave device.After receiving ACK,the host sends the 16-bit register address (where writing starts)and the 8-bit data bytes (to be written onto the register).The location of the register address pointer will automatically add 1after every Write Operation.Therefore,when the host needs to perform Write Operations on a group of registers of continuous addresses,it is able to write continuously.The Write Operation is terminated when the host issues the Stop condition.华信科专用c)Reading Data from GT9271(For example ：slave address is 0xBA/0xBB)Timing for Read OperationThe diagram above is the timing sequence of the host reading data from GT9271.First,the host issues a Start condition and sends 0XBA (address bits and R/W bit;R/W bit as 0indicates Write operation)to the slave device.After receiving ACK,the host sends the 16-bit register address (where reading starts)to the slave device.Then the host sets register addresses which need to be read.Also after receiving ACK,the host issues the Start condition once again and sends 0XBB (Read Operation).After receiving ACK,the host starts to read data.GT9271also supports continuous Read Operation and,by default,reads data continuously.Whenever receiving a byte of data,the host sends an ACK signal indicating successful reception.After receiving the last byte of data,the host sends a NACK signal followed by a STOP condition which terminates communication.华信科专用7.HotKnot7.1Start HotKnotWhen data needs to be sent,the host sends command 0x21to GT9271,enabling GT9271to enter "Master Approach mode"and work as a transmitting terminal.GT9271will then be able to detect the receiving terminal communicating with it.When GT9271succeeds in detecting the receiving terminal,it will notify the the host to shut off LCD using an interrupt signal and then transmit data to the receiveing terminal.7.2Data Transmission between TPsAfter GT9271and another Hotknot terminal successfully detect one another,the host sends the HotKnot transmission firmware to both terminals.While the transmission firmware runs,the two terminals are ready for data transmission,entering Receive mode by default.When the GT9271Transmit Buffer is flushed correctly,GT9271works as the transmitting terminal and immediately transmits data to the other HotKnot terminal,which works as a receiving terminal detecting data sent by GT9271.7.3Host Receives Data from GT9271Following recieval or transmission of a data frame,GT9271inverts INT to notify the host to process data.After receiving a data frame,the the host reads the value of the HotKnot-featured status register.If the value of the receive-status register indicates a successful reception,the host will read the data from the Receive Buffer via 12C.After reading the recieved data,the host writes 0xAA to the designated address and notifies GT9271that data reading is complete.After GT9271transmits a data frame,the host reads the value of the HotKnot-featured status register.If the value of the transmit-status register indicates a successful transmission,the host will read the data from the Transmit Buffer via 12C.After reading this data,the host writes 0xAA to the designated address and notifies GT9271that data reading is complete.GT9271will automatically switch to Receive mode and will not start transmitting until Transmit Buffer is flushed again.华信科专用8.Description on Functions8.1Operating Modesa)Normal ModeWhen GT9271is operating in Normal mode,its coordinate refresh period is subject to configuration (5ms to 20ms valid,one step is 1ms).When no touch is detected for a certain period (0s to 15s,subject to configuration;one step is 1s)in Normal mode,GT9271will automatically switch to Green mode to reduce power consumption.b)Green ModeIn Green mode,the scan period for GT9271is about 40ms.It automatically enters Normal mode if any touch is detected.华信科专用c)Gesture ModeAfter the host enables GT9271to enter Gesture mode by sending I 2C command 8to 0x8046and then to 0x8040.Wake-up can be achieved by swipe,double-tap,or writing of specified lower-case letters on Touch Panel (TP).In Gesture mode,when GT9271detects any finger swipe for a sufficiently long distance,double-tap or writing of specified letters on TP,INT will output a pulse for longer than 250us or output a high level.The host will wake up and turn on the screen after receiving such pulse and high level.d)Sleep ModeGT9271enters Sleep mode if it receives the corresponding I 2C command from the host (require INT output low before the command).GT9271exits Sleep mode and enters Normal mode when host outputs a high level to INT pin for 2ms to 5ms.The interval between sending screen-off command and wake-up should be longer than 58ms.e)Approach ModeWhen HotKnot proximity detection is enabled,GT9271enters Approach mode by default.If GT9271exits Approach mode,the host can send command 0x20or 0x21to enable GT9271to enter Approach mode again.In this mode,touch detection and HotKnot proximity detection alternate.If the host sends 0x21to GT9271,GT9271will work as a transmitting terminal and transmit signals with a specified pattern and frequency via Tx and Rx channels.Then,GT9271detects whether there are feedback signals with the same specified pattern and frequency from the receiving terminal.This helps to determine whether any receiving terminal exists.If the host sends 0x20to GT9271,GT9271will work as a Receiving terminal and detect signals with a specified pattern and frequency from the transmitting terminal.If such a signal is detected,GT9271responds using signals with the specified pattern and frequency to the transmitting terminal.In Approach mode,when detecting any HotKnot-compatible terminal within the near-field range,GT9271will notify the host via INT to capture status.To ensure reliable detection between the transmitting terminal and the receiving terminal,it is required to keep detecting for a minimum of 150ms after the two terminals have detected each other.Then the host sends HotKnot transmission firmware to enable GT9271to enter Receive mode.华信科专用f)Receive ModeIn Approach mode,after notified that GT9271has successfully detected another HotKnot terminal,the host sends HotKnot transmission firmware to enable GT9271to enter Receive mode.In Receive mode,GT9271continues to detect frame start signal,once the signal is detected,GT9271begins to detect and receive data.When the receiving process is complete,GT9271verifies the data.If GT9271finds erroneous data,the receiving process begins again.If the data is found to be correct,GT9271notifies the host via INT to read data in the Receive Buffer.g)Send ModeWhen GT9271works in Receive mode,the host sends outgoing data to the Transmit Buffer.When detecting that the Transmit Buffer is flushed and there is data to be sent,GT9271automatically switches from Receive mode to Send mode.In Send mode,GT9271sends a frame start signal.If it detects ACK fed back from the receiving terminal,it continues to send the data signal.After sending a data chunk,GT9271begins to detect ACK.If it does not detect any ACK or if it detects an erroneous ACK,GT9271will resend the data chunk.If this resending fails over 5times,it will resend the current data frame another time to the receiving terminal until the host enables GT9271to exit Send mode due to timeout.If GT9271detects ACK and sends the data successfully,it will automatically switch to Receive mode after the host completes the data processing or due to timeout.8.2Interrupt Triggering MechanismWhen touched,GT9271sends a pulse via INT pin in every scanning cycle to notify the host to read coordinates.Host will then set a triggering mechanism via relevant register “INT”bit.INT as “0”indicates rising edge-triggered,which means GT9271will notify the host by driving INT output from low to high when operated by user;INT as “1”indicates falling edge-triggered,which means GT9271will notify the host by driving INT output from high to low when operated by user .8.3Sleep ModeWhen the touch screen is off or there are no running operations on the TP ,the host sends I 2C command to enable GT9271to enter Sleep mode,which reduces power consumption.When GT9271needs to operate,the host outputs a high level to INT pin for a certain period to awake it.For detailed timings of host enabling GT9271to enter and exit Sleep mode,please refer to section 8.1.8.4Stationary ConfigurationGT9271supports Stationary Configuration.After receiving configuration parameters from the host,GT9271will fix parameters to the latest version.Once these parameters are fixed,GT9271will communicate with the host solely via I2C bus and will not receive any parameters of previous versions from the host.华信科专用8.5Self-calibrationa)Self-calibration during InitializationFluctuations in temperature,humidity and environment may affect the baseline of the capacitive sensor in idle state.GT9271will update detection baseline according to environmental conditions within the first 200ms of initialization.Then,GT9271will complete the initialization of the TP test.b)Automatic Drift CompensationGradual changes in environmental factors such as temperature,humidity,or dust may also affect the baseline of the capacitive sensor in idle state.GT9271will detect real-time changes in data and perform statistic analysis of historic data to revise the baseline and thus reduce the impact that environmental changes have on the TP test.华信科专用GOODIX CONFIDENTIAL9.

一、 概述
基本工作原理
HA3516 采用矩阵扫描方式实现更多触摸按键的解决方案采用定时充放电差值法，利用固定时间对转 换模块电路进行充放电，根据后端电平变化差值，获取有/无按键的状态。
固定频率和占空比的信号 PWM 通过电容耦合进入转换电路，经二极管反向续流后会形成带直流分 量的脉动信号，简单滤波后输入到芯片内部进行检测。 当无按键时，该脉动直流电平是由稳定的电容的充放电、续流和滤波电路保持稳定。当有按键时候， 放电续流部分不会被改变，但充电部分受到手指加入的影响，相当于充电回路 RC 增大，在相同的 时间内，得到电压会比没有手指时候低。所以，在手指接触感应电极的时候，该点的直流电位下降 了。通过该直流电位的变化情况，分析是否有手指按键。 同一按键检测口上在外围硬件上连接了两个不同的感应按键，当 PWM1 和 PWM2（Pulse drive）快 速地分时切换，分别对两组按键进行检测。通过上述方式实现了 2x8 的矩阵扫描。 当手（人体）非常靠近或接触按键感应焊盘（或弹簧）时候，由按键检测电路提供给芯片的电压会 发生改变，体现为该电压下降。具体过程如下图所示（以下数据是在 5v VDD 供电，5mm 玻璃覆盖 厚度情况下测得）：

电容式触摸型遥控解码控制芯片 TK500R
一、概述
TK500R 芯片主要用于智能家居电容式触摸墙壁开关的核心控制单元电路 应用，TK
◆ 该产品具有如下功能特点和优势：
电源开关控制信号输出。 采用CMOS工艺，低电压损耗，VDD电压范围宽：2.7V ~ 5.5V。 集成触摸按键功能，使用较少的外部元件便可实现触摸按键的应用。 外围电路简单，成本低廉。 兼容PT226X、EV1527遥控编码信号。 每个触摸按键可学习五组(自锁(3组)、全开(1组)、全关(1组)) 遥 控编码数据，密码、遥控代码完全独立存储。
3.2 初始状态
初始上电时，控制引脚 LAMPX(X:1-5)为低电平状态、BEEP 无蜂鸣信号输 出。
3.3 学码方法
在触摸输入引脚(如TK1)持续保持输入信号约4.5秒，TK500R 芯片将进入遥 控编码学习模式（此时无论LAMPX(X:1-5)是否为高电平，进入学习模式后都 将变成高电平）。 BEEP信号输出引脚在进入学习模式的这一刻产生一组 30mS长，频率为2KHz的方波信号，如外接有蜂鸣器将会“滴”的响一声（代 表学习当前触摸输入引脚(如TK1)相应的自锁遥控码）。触摸正在学习的触摸 按键（如TK1），会跳过正在学习自锁的按键码，开始学习全开遥控码，同 时BEEP蜂鸣器将“滴、滴”地响两声（频率2KHz，持续时间30mS，间隔200mS 的方波信号；代表学习全开遥控码）。相同的方法可跳过全开遥控码的学习， 开始学习全关遥控码，BEEP蜂鸣器将“滴、滴、滴”地响三声（代表学习全 关遥控码）。如果再次触摸正在学习的触摸按键，TK500R 芯片将退出学习

在以上3个项目都固定的情况下，对芯片Cs电容容量进行调节也能获得不同的灵敏度。 芯片在运算的过程中需要采用Cs电容来做为基准参照，对Cs电容的调节能改变芯片运算，获 得不同的触发门槛值，从而影响到触摸灵敏度。
