Hi,
I'm trying to send all 1's to output pins of dspic33fj128mc202. My programming and verification is done correctly. But there is no voltage at output pins. Here's the code
Code:
#include <p33FJ128MC202.h>
int main(void)
{
AD1PCFGL = 0xffff; //All analog capable pins in digital mode
TRISA = 0; //All pins output
TRISB = 0; //All pins output
PORTA = 0xFFFF; //All pins low
PORTB = 0xFFFF; //All pins low
while(1);
return 0;
}
The output at all pins is :
Pin28: 3.3v
pin13: 3.3v
Pin1: 3.3v
Pin20: 2.6v
All other pins: 0v
can the IC be damaged?
What are the indications that a dspic is damaged?
please help..

Can you program the chip? Can you single step through the code? What does your schematics look like?
