I´m having a strange behaviour on my LEDs: a lot of flickering (for the annunciators that should light), some Annunciators light up that shouln´t, some annunciator, that should not go on, light up very little, as they would shine a little tiny bit of light.
Notes (could be issues maybe?):
a) I have different LEDs colors (with different forward voltages 2,1V/3,2V) on the same Driver
b) I´m powering the drivers with Arduino +5V
c) I ordered new DM13A drivers from another source (DIP format). the actual ones came from china with SSOP24 format but with 1,0mm spacing, so had to get some rare Adapter boards... well lets see if that changes something
d) I´m using different Rext resistances, but they dont seem to change the brightness..also tried with potentiometer. Brightness is only affected when I slightly change the LED Voltage Power source between 4,5V and 6,5V.
I am building a complete Overhead for the B737-800 with SimVim. Each Annunciator consists of 2 LEDs in series connection. 5V 20A Supply Power used (Also powered up and set to 6,6V) for all annunciators.
Would appreciate your help a lot!
Thank you for the great plugin!
