I have a ATtiny412 that I am using to talk to a "listen only" SPI device. Tthe ATtiny412 is the SPI master, and I need it to control SCK and MOSI, but I do not want to use MISO for SPI.
I got the hardware SPI working by using the thread here: https://www.avrfreaks.net/forum/...
However, that code takes over the PA2 pin to dedicate it to MISO and I it does not appear that I can regain control of it.
Is that just a fact of life or is there a clever way to regain control of that pin?
I have software SPI written and working, it just seems a shame to not be able to use the hardware SPI :-(
Thanks for any help you can offer.
