Software Operation

The software allows programming control of the ADC3xxxx device. The front panel provides a tab for full
programming of the register map of the ADC3xxxx and an advanced tab that allows for custom register
accesses. The GUI tabs provide a convenient and simplified interface to the most used registers of each
device.
