adc.read_timed -- sampling interval error large

Open wangshujun-tj opened this issue 6 years ago • 0 comments

First of all, I would like to thank Loboris for his efforts on esp32.

I have tried two modules, PWM and adc, which are much more powerful than the mainline.

I tried to use read_time to get high-speed sampling, and found the following problems:

  1. Req RATE: 150000, real rate: 10416.000 request sampling rate and report sampling rate is about 16 times, but the error is very large.

  2. When performing read_time operation, a lot of information is always printed. Can a switch be added, because this may become a burden on the system and interfere with the normal printing information?
