| pic18f4550 and dspic30f3011 cant communicate |

Hi everyone. I have a problem. I can't communicate between dspic and 18F4550. When I try to communicate between two 18F4550, it worked. But I can't communicate with dspic. There are my code. What can I do ? | Code: |
#include <18F4550.h>
#fuses HS,NOWDT,PROTECT,NOLVP,NODEBUG,PLL5,CPUDIV1,VREGEN
#use delay(clock=24000000)
#use rs232(baud=1200,parity=N,xmit=PIN_c6,rcv=PIN_a3,bits=8,stop=1)
void main()
{
while(1)
{
output_high(pin_a3);
output_low(pin_a4);
if(input(pin_a5))
{
while(input(pin_a5))
{
putc('X');
delay_ms(250);
}
}
}
} |
| Code: | #include <30F3011.h>
//#device ICD=TRUE // For using the debugger, un-comment
#use delay(crystal=24mhz)
// UART1A specifies the alternate UART pins Pin_C13, Pin_C14
// use UART1 to sprcify UART for pins Pin_F3, Pin_F2
#use rs232(baud=1200, UART1A)
void main() {
output_high(PIN_B3);
delay_ms(250);
output_low(PIN_B3);
delay_ms(250);
while (TRUE) {
output_high(PIN_B4);
output_low(PIN_B3);
if(getc()=='X')
{
output_high(PIN_B3);
output_low(PIN_B4);}
}
}

How can you tell it doesn't work. As soon as you toggle your LEDs for 'X', you toggle them right back immediately. The LEDs will appear to not change at all.
Also, you are not using the ERRORS option in your #use RS232() statement like you should be. Hardware can lockup otherwise. |
