TCA9535 IO expander #12

Open zacharyburnett opened 8 years ago

zacharyburnett commented 8 years ago

We will need the TCA9535 IO Expander by Texas Instruments for pin interrupts, to expand available pins for a larger number of sensors.

This code will need to be written in AVR instead of Arduino, because the individual sensors of Balloonduino will use unused pins invisible to the Arduino language.
