HAT - can't find function "set_voltages_callback_configuration"


Recommended Posts

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

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.
