I have a Moteino M0 with flash and radio.
One of my projects does not require flash, radio, SPI, I2C, or Serial1.
How do I repurpose these pins (SCL, SDA, MISO, SCK, MOSI, RFM SS, FLASH-MEM SS, RX1, TX1 as GPIO pins ?
I am finding that some pins (e.g. MISO) refuse to cooperate through the regular pinMode and digitalWrite commands (e.g. to light an LED).
Thanks
