So, no hints or suggestions? I tried a code found on the net:
#include <stdio.h>
#include <8051.h>
void main (void) {
SCON = 0x50; /* SCON: mode 1, 8-bit UART, enable rcvr */
TMOD |= 0x20; /* TMOD: timer 1, mode 2, 8-bit reload */
TH1 = 0xf3; /* TH1: reload value for 2400 baud */
TR1 = 1; /* TR1: timer 1 run */
TI = 1; /* TI: set TI to send first char of UART */
printf("Hello, world!\n");
while (1) {
;
}
}
then compiled with `sdcc main.c' and tried to simulate:
# echo run | s51 -s/dev/pts/1 main.ihx
but I get no output on /dev/pts/1!
What am I missing?
Thank you!
