ESP32S2 time.sleep() issues #2958
Description
While I was testing out the code for #2931 I found some issues with how time.sleep() is working for the ESP32S2.
- Float values passed seem to be rounded up to the nearest integer.
- Passing a small float value like
0.001causes a board to crash on boot (serial output below). Since the board no longer mounts because of that, the only solution I was able to find to get a board working again was to runidf.py erase_flashthen reflash CP.
Hardware tested on:
- Espressif Saola Wrover
- A custom development board
Commit for the build I was using:
commit 3bb6a32a2078452d3278b185a15721391d78a9db (HEAD, tannewt/esp32s2_digitalio)
Serial output after hard reset (Saola):
