One pin dual outputs
October 12, 2010
I have an inexpensive R/C car w/ the TX2/RX2 chipset. Typically, one would use a single pin per function on the RX2. Using that logic on an 8 pin PIC would leave me with 2 pins, one input and one output. After reading about the Ladybug Clone, I wondered if could get away w/ splitting the output of a single pin, one inverting and one non-inverting using a NOT gate and tri-stating the pin when I didn't want either output high.
