Awesome!

Thank you both ESP_Sprite and MicroController.

That's answered my query nicely.

Hi,

Multitasking is new to me, as is the ESP32 and ESP IDF framework.

I'm using a float variable, to share a value between tasks. Were it a 32-bit variable, I believe it's writes would be atomic. As a float value, however, I'm concerned that the reading task may acquiring the value, right in the ...

Maybe this will clear-up my earlier post:

Just trying to measure some simple voltages and currents.

I believe that the C3 and S3 variants have an improved ADC. If you extrapolate their linear regions for conversion, they intersect the y-axis at the origin.

For the same extrapolation, the ESP-WROOM-32 I'm using has a significantly non ...

Just discovered that the ESP-WROOM-32 I'm toying with, has a rather odd ADC.

With other controllers, a simple voltage divider has provided a suitable ADC input voltage for measurement of a full-range voltages.

Now, it appears that I need to both divide a measured voltage, as well as translate it ...
