Here is the code I am trying to compile:
| Code: |
char menu(void);
void main()
{
while(1)
{
switch (menu()) {
case '1': {
output_bit(PIN_A0,1);
delay_ms(1000);
output_bit(PIN_A0,0);
break;
}
case '2': {
output_bit(PIN_A1,1);
delay_ms(1000);
output_bit(PIN_A1,0);
break;
}
case '3': {
output_bit(PIN_A2,1);
delay_ms(1000);
output_bit(PIN_A2,0);
break;
}
default: {
output_bit(PIN_A0,0);
output_bit(PIN_A1,0);
output_bit(PIN_A2,0);
break;
}
}
}
///////User Selection Menu//////////////////////////////
line 54: char menu(void)
{
char ch;
printf ("\n\r Press A to turn LED on RA0 .......");
printf ("\n\r Press B to turn LED on RA1 .......");
printf ("\n\r Press C to turn LED on RA2 .......");
ch = getc(); //wait for and get serial character
//delay_ms(100);
return ch;
}
/////////////////////////////////////////////////////////
