8051 c programming
Hi
I am new in C programming, but have done a lot of 8051 assembler programming before.
I am using SDCC as compiler.
I am trying to make a "Hello world" program.... with difficulties!
Take a look:
#include <8051.h>
void pause()
{
unsigned int x;
for(x=0; x<33000; x++);
}
main() {
for(;
{
P3_6=0;
pause();
P3_6=1;
pause();
}
}
.....
I have a LED connected to P3.6 on my board and the LED is constantly off when the program is running.
Why is it not flashing?

Well.... the problem is solved! The LED is flashing.
That port on my development board was used to another funkcion that that was blocking the state.
