hello everyone.....i made a General Annunciator Pannel, but some ones indicattions, shows a fade bright led, when i use a ARDUINO skecth to test, all of them are shining if the same bright, but when i start the MF, just some side of leds, seems weak bright.

Hi

I can not open your Link.

Basicly Mobiflight just set a Pin to High or Low..... So there can be no difference of Brightness..... All Digital Pins work same way.

Possible Problems.....

Overall Power Problem. Maby you have to much Power-Need Elements on that board or your Power Suply not have enough power itself.
Wire Problem..... short Circuits .... wrong Resistors .... Wrong Ground Logic

Without see your sheamtic i cant help you..... But i would say 99% a wire issue.

hello PIZMAN82... i am using a simple electric scheme, with a BC548 transistor with 1K OHM and 220 OHM TO LED, i am using a pc power suply, but strange is how i said before, that testing in arduino sketch program, works perfectly.

Please confirm this also happen with a verry basic and clean config ( for example a new file with just one config ( parking brake led tutorial)

I remember to a issue in my testing system some years ago....

If you have 2 Configs that both controll same LED ( For example a Off Config for a precondition or you did a mistake and choose the same LED for 2 different things) then this error can occure.
If Config 1 will set LED to ON and same time Config 2 set LED to OFF then it "flicker" 30-40 of times per second that occure for the human eyes as lower brightness ( PWM Logic)

If posible check if you have choose this LED Device multiple times in case of a issue OR if you have Precondition logics that not work correctly and are enabled same time.
Always remember.... A LED should be never controlled by more then one config at a time.

ok...thanks...i am going to test these
