I don't want to remove the lower percentage display bightness just because some radio's have a noise when those values are used.G4EML wrote: ↑Sun Mar 20, 2022 9:53 pmMy radio has been in the cupboard for the last two years so I haven’t kept up with the official firmware and didn’t notice the dimming had been added.
We could probably do the same three or four preset levels at a higher frequency, it’s trying to get a smooth 0-100% that’s difficult.
Better to have 5 different PWM frequencies in a table e.g.0 - 19%, 20% - 39%, 40% to 59%, 60% to 79%, 80%+
Then use those values.
Or perhaps even 10 steps, but below 10% I know the PWM freq must be fairly low otherwise the backlight goes off completely
