high humidity causes dead lock #23

Open GottZ opened 1 year ago

GottZ commented 1 year ago

Hey there. I've just noticed blowing slowly onto a HTU21D causes .relative_humidity to dead lock main thread execution. image image

is this reproducable outside my home? I'll check the behavior with a second HTU21D on friday. any idea for a workaround?

Which QT Py is that? This may be microcontroller-specific. The ESP32-S3 I2C implementation can be flaky. If you have another microcontroller board, try that one as well.

GottZ commented 1 year ago

it's a esp32-s2

Adafruit CircuitPython 8.1.0-beta.1 on 2023-03-30; Adafruit QT Py ESP32S2 with ESP32S2
Board ID:adafruit_qtpy_esp32s2

I'll check with a flipper zero later. thanks.

I Was not able to reproduce this using

Adafruit CircuitPython 8.1.0-beta.2 on 2023-04-26; Adafruit QT Py ESP32S2 with ESP32S2

Using simpletest with and sleep time of 0.1.
