Experimental library for the AD9833 function (waveform) generator (12.5 MHz) The library supports both hardware SPI and software SPI. The AD9833 is a signal generator that has two channels for ...

Unfortunately, the AD9833 doesn’t have a way to control amplitude, something which is pretty important in a function generator. So [Faransky] uses a X9C104P 100KOhm 8-bit digital potentiometer ...
