一个arm7实验板上ad按键控制程序,此按键控制AD实验由c语言编写。-a arm7 experiment on-board ad button control procedures, key control of AD in this experiment was conducted by c language.
verilog编写,将I2C串行数据转化为并行数据的功能模块,类似于PCF8574芯片的功能。以后不用买另外的芯片就可以直接将并行数据连到I2C总线上了-Verilog prepared to I2C serial data into parallel data of the function modules, similar to the function of PCF8574 chip. After the chips do not have to buy another can be connected directly to the parallel data to the I2C bus on the
