Hi

I purchased chipKit Max32 latest board and found that LD5 (LED) is connected to pin 6. I added int ledPin = 6; in the blink sketch and uploaded it to Max32 but the LD5 doesn't blink or turn ON. Have I received defective board? I purchased it from Microchip.

No, because LD5 isn't on pin 6, LD5 is on pin 86.

Also, the Blink sketch in MPIDE doesn't use an "int ledPin" variable, but #define macros, such as PIN_LED1 and PIN_LED2 (PIN_LED1 by default). Changing them to PIN_LED2 will make LD5 blink without you having to know which pin it's attached to.

Thank you very much. I was checking PORTC pin 6 in schematic and thought it to be mapped to pin 6 of header.

I used

int ledPin1 = 13; int ledPin2 = 12;

in sketch for Uno32 and uC32 and they worked. I will try pin 86 for LD5 on Max32 and update.
