显示全部楼层
只做指路人，修行在个人：
1，STC32G12K128库函数下载路径：
2,范例程序文件夹如下：
3.Timer0-Timer1-Timer2-Timer3-Timer4测试程序
#include "config.h"
#include "STC32G_Timer.h"
#include "STC32G_GPIO.h"
#include "STC32G_NVIC.h"
/************* 功能说明 **************
程序演示5个定时器的使用, 均使用16位自动重装.
定时器0做16位自动重装, 中断频率为100000Hz，中断函数从P6.7取反输出50KHz方波信号.
定时器1做16位自动重装, 中断频率为10000Hz，中断函数从P6.6取反输出5KHz方波信号.
定时器2做16位自动重装, 中断频率为1000Hz，中断函数从P6.5取反输出500Hz方波信号.
定时器3做16位自动重装, 中断频率为100Hz，中断函数从P6.4取反输出50Hz方波信号.
定时器4做16位自动重装, 中断频率为50Hz，中断函数从P6.3取反输出25Hz方波信号.
下载时, 选择时钟 24MHz (可以在配置文件"config.h"中修改).
