Firmware for the Digital Potentiometer [0110123A]
The PIC16F15214 microcontroller firmware (HEX files) plus C language source code & MPLAB X project for the Digital Volume Control Potentiometer.
We suggest that you only use the 32dB gain version of the software if you need the extra gain. If you are not sure, use the standard version.
