Hi,

 

My board : Nucleo F429ZI

My Shield : Shield Version 4.03 by Joerg Amann & Stefan Rinke

 

My Pin2dmd work well when i use a usb cable on CN1 and JP3 on U5V.

 

But when i use an external power supply (+5V 60A) on the Shield board and JP3 on E5V, my Pin2dmd stay black.  I must press Reset button to start my Pin2dmd.

 

After some research , i found a soluce to this problem.

 

Soluce : Removing SB111 (resitor 0 ohm).

 

Now your Pin2DMD must be working without press reset button.

 

If not, i have modified my shield board before removing SB111.

 

I have cut the track (5V) beetween +5V connector and +5V rectangular pad.

I have tied +5V connector pin to pin 5 of CN1 (E5V) .

 

Now i hope that will work for you too.

 

PS (Sorry for my english)
