Hello, everyone!
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()
{
GPI0D- >DDR |=0x03;
//PD3 as Output
GPI0D- >CR1 |=0x03:
//PD3 as Push Pull
while
GPI0D- >0DR|=(1<<3) :
//turn PD3 on
de1ay_ ms (1000):
GPI0D->0DR&=' ~ (1<<3) ;
//turn PD3 off
delay_ ms (1000) :
}
}

Hi,
Your code has a lot of bugs. Typos in functions, function declaration is different from function definition, a colon instead of a semicolon etc.
Delete spaces in several places. Look carefully at your code.

Probably, function delay_ms has been optimized out, so LEDs actually do blink yet too fast to be noticed.
