Facchini75 Posted March 2 Share Posted March 2 Hi everyone. Excuse me but I need your help. I made some pin2dmd for my pinball machines with Nucleo 144 model F439ZI and Nucleo 144 shield. Unfortunately, out of 4 displays created, 2 have the problem of not being able to write and read data from the SD card. I don't think it's a shield problem because if I change the Nucleo 144 board then it starts saving on that shield too. What do you recommend I check? Thank you for all the help you can give me Link to comment Share on other sites More sharing options...
