First install sdcc
#yum install sdcc
Next is a small example to blink a LED connected to P1.7
#include <8051.h>
void main(void)
{
int i=1;
P1=0; /* P1.7 used as LED output /
while(1)
{
P1_7=!(P1_7); / toggle P1.7*/
for(i=1;i<25000;i++); /* for delay */
} }
Compile it and get the hex file from intel hex
$sdcc-sdcc blink.c
$ sdcc-packihx blink.ihx > blink.hex
Now you can upload the hex to the programmer :D /me is also just starting up.
