|
||
12 本例程基于STC8H8K64U为主控芯片的实验箱8进行编写测试，STC8G、STC8H系列芯片可通用参考.
|
||
13
|
||
14 双串口全双工中断方式收发通讯程序。
|
||
15
|
||
16 通过PC向MCU发送数据, MCU收到后通过串口把收到的数据原样返回, 默认波特率：115200,N,8,1.
|
||
17
|
||
18 通过开启 UART.h 头文件里面的 UART1~UART4 定义，启动不同通道的串口通信。
|
||
19
|
||
20 用定时器做波特率发生器，建议使用1T模式(除非低波特率用12T)，并选择可被波特率整除的时钟频率，以提高精度。
|
||
21
|
||
22 下载时, 选择时钟 22.1184MHz (可以在配置文件"config.h"中修改).
