  • Has anyone else had any problems with false low readings on IO pins? I have the DDRD set properly and am trying to read input PIND7 on PORTD. I am outputting the register over the serial port, it shows that pin 7 is low, but I can read it with a multimeter and it is at 5V. I have also output the DDRD to verify that DDD7 is a low, for input.

    Is this a problem coming from the booloader? I have actually been flashing the board over SPI using a MKii programmer. Has anyone else had this issue? Help?!?!

No public wish lists :(
