[SOLVED] Pin2dmd wrong colors displayed

[malcom1970]

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.

Hi @lucky1,

could you help me with this issue ?

Do you think it’s linked to bad resistance or capacitor ?

thank you in advance

bad connection to pin 1 of the hub75. Red is missing.

Thank you Master Lucky 😉

 

You're the king 😉

 

I had a bad soldered pin on my Nucleo 439.
