Ran out of memory with the UNO. Had to move to the MEGA.
What is the deal with SPI and I2C moving to new pin on the board.
I have a RTC / SD shield for a UNO that I wanted to use.
I have UNO SPI PIN working with software SPI.
I still have to find a solution to I2C on the MEGA using the UNO pins. Is there a software lib for this also?
Why did they not just leave them where they were?
