Question

STM8S103F3P有8位定时器4吗?

Answer 1

有。
#include <iostm8s103f3.h>
#define uint unsigned int
#define uchar unsigned char
#define ulong unsigned long
void delay_ms(uchar ms)
{
uchar i,j;
while(ms--)
{
for(i=4;i!=0;i--)
for(j=100;j!=0;j--);
}
}
void timer_Init(void)
{
//TIM2/3/4/5/6须使用与芯片对应的头文件
TIM4_PSCR_PSC = 1; //2^1 分频为1M
TIM4_ARR = 0xC8; //每200us中断一次
TIM4_IER = 0x01; //允许更新中断
TIM4_CR1 = 0x01; //计数器使能，开始计数
}
void main(void)
{
asm("sim"); //关总中断
timer_Init();
while(1)
{
asm("nop");
}
}
#define TIM4_OVR_UIF_vector 0x19
#pragma vector = TIM4_OVR_UIF_vector
__interrupt void TIM4_OVR_UIF(void)
{
TIM4_SR_UIF = 0;
//add your code here
}
