AVR-based footswitch controller for MIDI appliances.
The current implementation supports 4 pushbuttons and 1 toggle switch (usually bank switcher) and a hard-coded range of MIDI sequences.
Hardware os based on a single ATtiny2313 microprocessor.

Original design intended to retrofit an analog _Vox VFS5_ footswitch to control an _Axe-Fx II_ effect processor by _Fractal Audio Systems_.
## Hardware Specs
Hardware is designed to work with a power supply of 7 to 25V DC which is suitable for a standard 9V DC power supply or battery which is common for effect pedals.
The logic is powerd by a Atmel/Microchip ATtiny2313 processor, which can be swapped with about any AVR controller proividing 8 I/O ports and a USART interface.
The logic is powered by a Atmel/Microchip ATtiny2313 processor, which can be swapped with about any AVR controller providing 8 I/O ports and a USART interface.
MIDI signal is directly connected to the USART output (active low) of the controller and the 5V DC supply of the board through two 220 Ohm resistors.
