Hello.

I'm using your library for Python, version 2.1.23,

When I try to use function "set_voltages_callback_configuration", (see link https://www.tinkerforge.com/en/doc/Software/Bricks/HAT_Brick_Python.html#BrickHAT.set_voltages_callback_configuration), then I got an error in my code.

When I open your file brick_hat.py, then I see that this is missing...

Best regards

The set_voltages_callback_configuration function is new and not part of Python API bindings version 2.1.23. It will be part of version 2.1.24 that will be released this week.

OK. I found it in the description on the page, see my earlier link, and therefore I thought it was OK. In any case, that what the function I like to use.
Understand, I'll wait until next  release.

..

Sorry, I didn't manage to finish the release today. It'll be released on Monday.

Python API bindings version 2.1.24 is now available.

I'm using Python API version 2.1.24 and is testing callback_voltages.
With the function "BrickHAT.set_voltages_callback_configuration(period, value_has_to_change)" I should be able to set value_has_to_change with True or False.
But when I test it, with False or True I still get values every period time.
I could change the period and it work's, I have tested for example with different times like 1000, 2000 3000.

What do I do wrong ??

Hi,

Have you printed the values each period? I'm assuming, that your power supply is fluctuating enough, that the HAT can measure this. (I've just tried this here with a USB power supply and can reproduce it.) So the value is in fact changing every period.
