lololo Posted December 10, 2019 Share Posted December 10, 2019 Hello, I'm trying to run my pin2dmd but I do not have anything on the screen. The first time, I had a few lines because I was wrong on the solder card sd ... but now I have nothing that appears. The Nucleo is in V3. the leds are well fed in 5v but nothing works ? The problem is that I do not know where to start to check? Can you help me. Thank you and good day. Ps: I have not yet put all the components for the pinball part, I think it does not matter!

latenite04 Posted December 10, 2019 Share Posted December 10, 2019 It looks like your Max232 chip is backwards, the notch should be on the other side, and you are also missing capacitors c1-c7. Link to comment Share on other sites More sharing options...

latenite04 Posted December 10, 2019 Share Posted December 10, 2019 You are probably right about the parts, I have never built a shield just for a vpin. I would check and re-flow the solder joints on your headers. I have had a shield that gave me a blank screen and it was a bad solder joint on the header. Did you re-flash the nucleo board with the firmware? Link to comment Share on other sites More sharing options...
Content Provider lucky1 Posted December 10, 2019 Content Provider Share Posted December 10, 2019 Wrong Nucleo. The only one supported is the F429ZI. You have the F746. Link to comment Share on other sites More sharing options...

lololo Posted January 30, 2020 Author Share Posted January 30, 2020 Hello After a long wait, I finally received my Nucleo F429ZI. I flashed it with the latest version of PIN2DMD and I still have the same problem, nothing on the screen. I want to cry ? So here are some screenshots if anyone can help me? Thank you and good day.

Content Provider lucky1 Posted January 30, 2020 Content Provider Share Posted January 30, 2020 Maybe you did not download the firmware binary, but the website html. Just click on the download button on this site to get the correct file https://github.com/lucky01/PIN2DMD/blob/master/firmware/latest/V4 NUCLEO-144/PIN2DMD.bin or use this link https://github.com/lucky01/PIN2DMD/blob/master/firmware/latest/V4 NUCLEO-144/PIN2DMD.bin?raw=true Also please make a picture of how you connected the panels The downside connector is for piggyback installation and not for ribbon cables. Please connect the ribbon cable to the topside HUB75 connector. Link to comment Share on other sites More sharing options...
