Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Thanks Phil, I have a Ver1.2 display with Q1 so the fix should be easy.
Maybe a separate version of the firmware for audio or have the Backlight like the PWM command where you can stipulate frequencey and %.

I'll change the backlight command to allow you to optionally specify the frequency. The default will still be 50KHz on powerup

BACKLIGHT 50 [,freqinHz]

Peter changed the Backlight command andit works ok in WebMite V6.00.02RC10 but
in thelatest version of the PicoMite firmware V6.00.02RC24 it no longer works.

Yes, you must have an issue there.
Tested V6.00.02RC24 and "backlight 50,1000" produces 1kHz at 50% on the backlight pin.
