malcom1970 Posted April 27, 2021 Share Posted April 27, 2021 Hi everybody, I made a V4 Shield for nucleo Board 439 but i dont have the good colors, it seems the top part is blued. See the result on the photo. I already try these panels with my old pin2dmd and the colors are correct, so the issue is coming from the Shield or nucleo board. I also try to change the rgb sequence in the config menu but i never get the good colors. Could this issue be due to wrong resistance or capacitor ? See also the photo of my Shield, maybe someone could see something wrong with the soldered parts ? Hope someone could help me ? Thanks in advance.
