PWM is on Portc5 which is not used by the LCD.

I am using the PIC18F690 which has 20pins, 6 for port A, 8 for port c and 4 for port B. I need the 7 pins to run a LCD screen, 1 pin for a PWM output and 2 ADC inputs. So far the code for the LCD works fine alone, and the PWM code works fine alone, but when I put them together the PWM period doesn't...

Thanks, will try this out.

Not quite sure what the numbers mean in this following line:

if (Button(&PORTB, 4, 1, 1))

Portb pin 4 then what do the 2 1's mean?

Did the tem ever come up with a 10bit PWM resolution?

My code is trying to just swap the state of the output of portC. Originally, RC0 is on and RC1 and RC2 are off. When the button is pressed it should alter the state of the LEDs connected to PORTC. When I switch on, RC0 lights up and this is correct. When I press either button on B4 or B5 the lights ...

I'm trying to get the individual pins on my 16f690 to be controlled individually, like turn them on and off when I want. Seems like a stupid question but its not working for me. I can get my LCD working and PWM working, but to get an led to turn on and off on a pin is too hard as is working a button...

Oh my Hat! I would never have got that. You're awesome. Shot.

These two lines must be written in this order and your program will compile successfully:

Code: Select all

int i;
PORTC = ~PORTC;

The following code gives merrors such as invalid expression and undeclared identifier all pointing to the "for (..." line Its so stupidly simple, i;m not sure why its not working. void main() { PORTC = 0; // Initialize PORTC TRISC = 0; // Configure PORTC as output while(1) { PORTC = ~PORTC; int i; f...
