Title: LED brightness
Post by: Mr Rimmer on June 25, 2018, 12:07:12 pm

I've just had a quick play with LEDIson after updating to the 1206 ROM, and it looks like although the software supports 255 brightness levels, the LEDs don't dim accordingly.  A simple test is to create a sequence with one LED starting with full brightness, then duplicate the step, editing it to drop the brightness by 20 units.  Repeat a few more times then play the sequence.  The result is that the LED seems to flicker between steps but does not fade.

Yeah, that was my impression, too.

I also found another gotcha: if one LED is set to exactly the same value in every frame, it may not light at all!  The fix is just to tweak the colour very slightly between frames.
