dsPICFun Control Voltage development board

This is my version of Eric Brombaughs dsPICFun board. The original gerber files and schematics can be downloaded at his site here .
This board can generate four Control Voltages with a 12-bit DAC7554 for outputs and has four inputs hooked up to the ADC port. It also has 4 potentiometers hooked up to the ADC board two buttons and a rotary Encoder for values and settings.
It has a LCD port, DCI port , UART and SPI/I2C . Now this is where it gets interesting : the flexibility of the board is imense as it be configured for MIDI, RS-232 or USB. DCI port can take any Audio CODEC and I assume some memory handling might be possible with another µCU via the SPI port. Giving us a great and flexible dsPIC based Audio development sytem.

My Idea is to have some wavetables that leave the digital domain and are feed into a SSM2044 VCF that then is controlled by the CV of this powerful  µCU dsPIC33FJ128GP708 running @7.37MHz.

But there are plenty other prjects that can be made with this thing like a MIDI to CV converter which is almost a waste and processor overkill.

I must say that I didn't have any trouble building this thing and can only recommend it to everyone in the SDIY community.
