通过python+PYQT5写的上位机，USB转 IIC测试过 windows 64位系统运行

Ginkgo USB转I2C适配器的上位机软件，很方便对I2C接口的芯片进行读写控制，对验证I2C接口的芯片功能很有帮助！

基于CH554的电容屏IIC转USB接口的代码程序，下载即可使用，是HEX不是源码，不接受的别下载。

UK532-USB2I2C makes it possible to interface different kind of user applications to the PC over USB, without any need of µC controller programming. The Chip can be used as I²C/I2C/IIC/TWI/SMBUS interface to i²C enabled peripheral IC´s. It also offers an 8bit bi-directional databus with EPP/MEM protocol, which could be used to interface HD44789 compatibl etextLCD displays for example. Programming is made easy using an API-DLL,suitable for almost any programming language (Delphi,CBC,C,VB,LABVIEW...).
