| CCS C & MPlab v7.6 simulator |

Hi there,
I am trying to simulate a PIC16f690 in MPlab using:
| Code: |
#include <16f690.h>
#fuses XT, NOWDT, NOPROTECT, BROWNOUT, PUT
#use delay(clock=20000000)
#use rs232(baud=19200, UART1, ERRORS)
void main(){
ENABLE_INTERRUPTS(GLOBAL);
enable_interrupts(INT_RDA);
while(1){
}
#int_RDA
data_handler(){
byte data;
data = getc();
putc(data);
}
|
And I am using the following as a stimulus:
| Code: |
61 62 63 20
wait 10 ms
63 62 61
wait 50 ms
"THE QUICK BROWN "
"FOX"
WAIT 200 ms
65 66 67 68 13 10 69 70
|
I'm getting a few correct characters but multiple instances of "UART-W0001: Overrun, write occured over a full TXREG SFR. Data lost" in the error window.
I have tried a low baud (9600) and the same happens.
Please advise,
Peter |

| Maybe you are not allowing time between incoming characters (pacing delay) - Im assuming your stimulus comes from a file? |
