IIC实验
代码说明:
开机的时候先检测 24C02 是否存在,然后在主循环里面检测两个按键,其中 1 个按键(KEY1) 用来执行写入 24C02 的操作,另外一个按键(KEY0) 用来执行读出操作,在 TFTLCD 模块上显示相关信息。同时用 DS0 提示程序正在运行。(When booting, it first detects the existence of 24C02, and then detects two keys in the main loop. One key (KEY1) is used to write 24C02, and the other key (KEY0) is used to read out, displaying relevant information on the TFTLCD module. At the same time, the DS0 prompt program is running.)
