Issue getting DOT Matrix with Blynk and Raspberry Pi to work

Postby meek424424 » Tue May 28, 2019 10:18 pm

Hello! I am following the tutorial for "Displaying Text Message on Dot Matrix using Blynk app and Raspberry Pi". I am using a Raspberry Pi Zero WH with the Maker pHat.

When I run the Python Script from the tutorial, I get an error for line 66 "blynk.set_user_task(my_user_task, 5000)". It states that there isn't a value set.

If I comment out the line, I will hear the pHat beep and I will see the text from the Blynk app appear in Python. This tells me that I have the Blynk app working with the Blynk server and the Maker pHat.

Please let me know what I am doing wrong. Is the syntax correct? I am sure it is something I am messing up. Thank you and I appreciate any assistance. :)

Hi meek424424, thanks for the feedback.

It seems like Blynk already update their library (on BlynkTimer), so the sample code provided also need to be updated. However, it will take some times for us to update the code. While waiting, maybe you can try to alter the code. Please refer the example code related to BlynkTimer here.

Thanks.
