In module 2.6 I get colored widgets. In module 3.1 I do not get colored text for the temperature reading. I did put in Serial.println(s) to verify going through color selection code. Got any ideas or can you point to another example of using colored text that I could try.
UPDATE: Not sure what I did, but I am now getting a color change for the text. Just not the right color. Blue is coming out Yellow, Red is coming out Blue and the Green looks like the same as the “Temperature” label (ie default).
LVGL 9.3.0

Hi.
It seems you have a slightly different board.
You probably have a board with two USB ports.
If that’s the case, you need to invert the colors. In the eBook, on page 90, we show two different options to fix the issue.
Also, on page 92 we show what to do if you have the board with two USBs.
Let me know if you can fix the issue.
Regards,
Sara

Thank you for the quick, intuitive and accurate evaluation of my problem without calling me out for not realizing during the initial display test that my text was white on black and not the desired black on white. I did in fact have 2 USB ports and a different driver.
It is refreshing to see a course that is aware and alerts to some common pitfalls ahead of time (even if I happened to overlook). Cannot say the same about some other vendor’s courses I have tried that don’t even work correctly with the components they supply and seem to lack quality assurance programs. Kudos to RNT.

Great.
So, were you able to fix the issue?
After setting the right configurations for that specific board, you shouldn’t have any other problems.
