I’ve spent a lot of time on this and hopefully can get an answer here from anyone who has written code for these addressable RGB chips. I have a PIC microcontroller running these and in the datasheet they show a global brightness 5 bit value of 0 to 31, preceded by a string of 111. MSB to LSB. So…in byte form, 224 would be OFF (and that works fine) and 1 - 31 would be values 225 to 255.
My question is this –
I see very (extremely) little difference in brightness of the led whether it’s at a low or high value. Right now, I have just the red led operating at 225 (1 !) and it’s only a hint less bright than 255. (31) – can anyone fill me in on this? thanks.
It’s way too bright for me even at 225.
