This project is meant to simplify designing USB MIDI controllers with the Microchip PIC16F1454 and PIC16F1455.
I chose the PIC16F145x because it is the smallest MCU I found capable of USB communication that doesn't need an external oscillator. The TSSOP-14 version is really small indeed...
Additionally, Microchip sells a PDIP version which is easy to prototype with.
I made a small break-out board to experiment with this chip [images]. If there is interest, I am willing to post the KiCad files online or ship some of my spare PCBs.
I'm planning to use this project as base for other MIDI controllers I design.
This project has to be opened in MPLab X IDE.
The system-functions handle device initialization, configuring the USB MIDI stack and LED updates. User code can be added in main.c. Usually no other files should be edited for simple applications.
Keep in mind that no code inside the main loop may block.
To program the PIC you will probably need a PICkit. Bootloaders could offer an alternative but I haven't investigated these yet.
This project uses the USB stack from Microchip Libraries for Applications.
