PS2手柄代码移植-合泰平台

PS2手柄代码移植-合泰平台
1、PS2手柄端口及通讯协议
PS2手柄的通讯协议是SPI协议是一种高速的、全双工、同步的通信总线，并且在芯片的管脚上只占用四根线（DI、DO、CS、CLK），PS2手柄的通讯协议破解后在C51、STM32、Arduino、FPGA等平台上均有应用，其端口、通讯协议及使用方法的介绍在网上一搜一大堆，大家自行下载即可。
博主本科期间由于项目需求，需要在合泰芯片上实现ps2手柄控制的代码。于是将ps2的代码从别的平台上移植到合泰芯片平台上，具体型号为合泰HT66F70A（好像是开发板型号，不一定是芯片型号），如今整理出来，希望能帮助到有需要的朋友。
2、移植代码：文件主要包括三份：ps2.c、ps2.h、main.c
