Chiptunes on the Three Cent Microcontroller (Padauk PMS150c)

This plays "Bitshift Variations in C Minor" by Rob Miles on the PMS150c. It needs no external components and is designed to run of a single CR927 lithium coin cell. The MCU detects automatically when it is plugged into a line input, and starts playing the music, and will go into a deep sleep once finished and disconnected. The project uses SDCC's assembler and the Free PDK toolchain.

Please check out the full write-up for more details!
