Limitations of using mm32 microphoton to generate dual audio signals
Introduction: The micro Python PWM module of ESP32 can produce a very accurate output frequency, but all micro Python PWM share the same Timer, so their fundamental frequency is the same. Two of the hardware timers can be used with MM32 micropathon, but the frequency accuracy of the output cannot meet the requirements. Therefore: either use oth ...

Micro Python transplantation PWM on MindMotion MM32 single chip microcomputer
Introduction: The software transplanted with micro python with PWM function sent by MindMotion on November 22 was tested. Firstly, the output waveform can be tested on the two PWM channels (PA6 and PA7), but there are still differences between the signal parameters and settings: the spectrum of the output PWM signal is smaller than the ...
