Hello!
I have bought a LK V3.8 with the PWM hat some years ago and tested it with a small LED strip and the dimming worked perfectly! Now, I tested again, including with a PWM fan and it was no longer working! I since also upgraded to the latest firmware (initially it was 1.47a, upgraded to 1.62) and it was even worse, namely the „PWM and PID” section on the device site (192.168....) was missing altogether! I reverted back to 1.47a and the PWM section is back.
Problem: PWM is always on and gives full 100% signal, no matter if I turn it off/on in the webserver (192.168...), if I change the dutycycle, etc... it stays full blast with no change!
What could be the cause and is it fixable?
Thank you in advance for any helpful advice!
