Hi Bill！
I have a new problem.When the device is in standby mode.
Why the period of DPWM signal is different from that of SLEEP?
Why is the waveform of 3v3_VCC unstable?
This is the waveform of SLEEP signal.(Its period is 360ms.)
This is the waveform of DPWM-A signal.（Its period is 4.6s.）
This is the waveform of 3V3_VCC signal.（Its period is 340ms.）
This is the circuit diagram.
They work normally when they are under load.
Best regards from China,
