Feel free to write it. Only a couple of hundred lines of complex C to support UART/SPI/I2C/PWM/IR and whatever I've forgotten. Whether rightly or wrongly the PicoMite supports very flexible pin allocation and this will always have positives and negatives. Detaching the pins puts them back in tristate mode so all that is needed is a pullup resistor to avoid the issue you identify. Not everything has to be solved in software Edited 2022-01-06 01:06 by matherp
