"Can´t convert NoneType to int" issue
-
Hello,
I am working on a simple program.
I receive a value between 0 and 1000 by MQTT and convert it to a digital value from 0 to 255.
Then I want to put it on the DAC channel 0.But if I want to proceed with the digital value within the main loop I get the error "Can´t convert NoneType to int".
I understand that this is a NoneType, which can´t convert into an integer, but I need to work with the digital value in the main loop, because I have to do some calculations (filtering), which is not possible in the MQTT function.
How can I solve this issue?

Are you using a “convert to int” block to convert the value being sent to the dac?
