The M5Stack DDS is a signal source Unit. It uses the AD9833 programmable waveform generator + STM32F0 micro controller. Based on I2C communication interface (addr:0x31) It can easily control the signal source to output multiple waveforms (sine wave, triangle wave, square wave output, sawtooth wave, signal output amplitude 0-0.6V) and adjust the frequency and phase.
Digital programmable f requency and phase Signal output amplitude 0-0.6V Sine wav e/Triangle wav e/Square wav e/Sawtooth wav e (f ixed f requency : 13.6KHz)/DC output Output f requency range: 0MHz to 1MHz (10MHz based on the ref erence clock) 28bit f requency resolution 11bit phase resolution
