I'm trying to program the serial port 2 on the XC161CJ infineon. But i can't achieve any interesting results. Ok, i've written code like this below, but, when i open the window serial #2, and i try to write something, nothing happen and seems that the XC161CJ goes to stall. Someone could please help me to understand how can i accept input from serial #2? thanks! #include <stdio.h> /* standard I/O .h-file */ #include <XC161.h> /* special function register XC161 */ #include <math.h> #include <string.h> signed char _getkey (void) { char c; while (!ASC1_RIC); c = (char) ASC1_RBUF; ASC1_RIC = 0; return (c); } /****************/ /* main program */ /****************/ void main (void) { /* execution starts here */ /* initialize the serial interface */ #ifndef Monitor /* do not initialize if you use Monitor-166 */ P3 |= 0x0400; /* SET PORT 3.10 OUTPUT LATCH (TXD) */ DP3 |= 0x0400; /* SET PORT 3.10 DIRECTION CONTROL (TXD OUTPUT) */ DP3 &= 0xF7FF; /* RESET PORT 3.11 DIRECTION CONTROL (RXD INPUT) */ ASC0_TIC = 0x80; /* SET TRANSMIT INTERRUPT FLAG */ ASC0_RIC = 0x00; /* DELETE RECEIVE INTERRUPT FLAG */ ASC0_BG = 0x40; /* SET BAUDRATE TO 9600 BAUD @ 20MHz */ ASC0_CON = 0x8011; /* SET SERIAL MODE */ ALTSEL0P3 |= 0x0C00; /* Configure port pins for serial interface 0 */ ASC1_TIC = 0x80; /* SET TRANSMIT INTERRUPT FLAG */ ASC1_RIC = 0x00; /* DELETE RECEIVE INTERRUPT FLAG */ ASC1_BG = 0x40; /* SET BAUDRATE TO 9600 BAUD @ 20MHz */ ASC1_CON = 0x8011; /* SET SERIAL MODE */ #endif while (1) { char nome[10]; int i=-1; nome[0]='a'; do { i++; nome[i]=_getkey(); } while (nome[i]!=0x0A); printf("il tuo nome è %s",nome); /* An embedded program does not stop and */ /* ... */ /* never returns.
