开启钱柜(Cash Drawer)和读取钱柜 open / close 的程序。透过对 ICH7 GPIO 的控制。适合生产线的测试应用。-Open Cash Drawer and read open/close the program. Through ICH7 GPIO control. Suitable for production line test applications.

在C#平台调用Ginkgo USB-I2C适配器或者Ginkgo USB-SPI适配器的二次编程接口函数实现GPIO读写控制功能，本程序对GPIO读写控制的各种模式进行了全面展示。-Call Ginkgo USB-I2C adapter or Ginkgo USB-SPI adapter quadratic programming in C# platform GPIO interface functions to achieve control functions to read and wr

基于STM32的使用GPIO口模拟IIC的源代码，已经过验证。（成功读取MPU6050数据）-GPIO port simulation based on the use of the IIC STM32 source code, has been verified. (Successfully read MPU6050 data)

实现SPI FLASH 通信，首先配置GPIO,然后初始化SPI FLASH DRIVER,获得FLASH ID,接着就可以读写SPI FLASH 了(Implement SPI FLASH communications, first configure GPIO, then initialize the SPI FLASH DRIVER, get FLASH ID, and then they can read and write SPI FLASH up))
