Topic: Does using ICSP for SPI free up D13, D12 and D11? (Read 539 times) previous topic - next topic

Hello,

I want to use SPI my D11-D13 pins are being used, if I used ICSP and D10 for SS, will this be independent of D11-D13?

Thanks,
Daniel

No. SPI uses pins 11, 12, and 13, regardless of whether the SPI device is physically connected to those pins, or not. On the 328-based Arduinos, that is.

The advantage of using the ICSP connection is that the Mega connects its SPI pins there, too, and they are different from the 328-based pins.
