Hello forum,
i am trying to get a standard linking led program running on my STM8S103F3P6 development board but i am not sure what i am doing wrong. I connected a LED to PIN D3, this is my code:
#include <stm8s.h>
void
delay_ms(uint16_t ms);
void
delay_ms(uint16_t ms){
while
(ms--){
uint16_t i;
for
(i = 0; i < ms; i++){
nop();
}
}
}
main()
{
GPIOD->DDR|=0x03;
//PD3 as Output
GPIOD->CR1|=0x03;
//PD3 as Push Pull
while
(1){
GPIOD->ODR|=(1<<3);
//turn PD3 on
delay_ms(1000);
GPIOD->ODR&=~(1<<3);
//turn PD3 off
delay_ms(1000);
}
}
#stm8 #gpio
