bicycle_odometer
@ivourshalldevour

A repository to hold all the code written for the MSP430 microcontroller I used while building my energy harvesting powered bicycle odometer. This bike odometer doesn't use a battery, so harvests energy from a small PV panel. Because of the very low amount of power available the very low power capable MSP430 microcontroller had to be used.
