ESP32 script hanging on 'adc.readADC_SingleEnded'
Posted: Thu May 06, 2021 2:49 pm
Hi all,
I have an ADS1115 connected to an ESP32 and I would like it to read voltages on the analog ports.
However, any script uploaded to the ESP stops running at the following:
adc.readADC_SingleEnded
No matter whether the ADS1115 is connected to the ESP32 or not and regardless of any other wiring solutions. I also tried different baud rates, different wiring solutions, different USB ports etc. Mostly using a 3.0V cell battery. But it didn't matter, the program just won't run, at least that's how it looks like from the Serial Monitor.
For completeness, here is a sample code ( also tried the example scripts provided in the IDE):
Anyone with ideas please?
cheers
