PIC16F145x_MIDI

Description
---
This project is meant to simplify designing USB MIDI controllers with the Microchip [PIC16F1454](http://www.microchip.com/wwwproducts/en/PIC16F1454) and [PIC16F1455](http://www.microchip.com/wwwproducts/en/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...](http://i.imgur.com/X8IG8gG.jpg)
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](http://imgur.com/a/j5HQL)]. 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.
Usage
---
This project has to be opened in [MPLab X IDE](http://www.microchip.com/mplab/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```](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](http://www.microchip.com/Developmenttools/ProductDetails.aspx?PartNO=PG164130). Bootloaders could offer an alternative but I haven't investigated these yet.
