Brightness slider inaccurate #4105

Closed blake-nouribekian closed 3 months ago

blake-nouribekian commented 3 months ago

What happened?

The brightness slider does not work correctly. I get to full brightness on the LED's when I get to 19/255 brightness. Going any higher does not increase the brightness.

To Reproduce Bug

Not sure if this causes any issue but I have "Enable automatic brightness limiter" on and set to 1000mA. Turn on the LED's and slide the brightness in the upper right hand corner.

Expected Behavior

The brightness mapping for the slider will change the LED's brightness from 1 to 255

Install Method

Binary from WLED.me

What version of WLED?

0.15.0-b3 (build 2405180)

Which microcontroller/board are you seeing the problem on?

ESP32

Relevant log/trace output

No response

Anything else?

No response

Disable brightness limiter. Brightness works as expected.

By disabling the limiter, that would let the LED strip draw more power than the PSU can handle if it is lower than the LED strip. Wouldn't that cause an issue?

The brightness limiter is meant to protect your wires. If you use thin wires and the current is too high, then wires will get extremely hot. It also protects your esp board, in case you power the led strip directly from the 5V pins on the board.
