Install Pin2DMD in a real machine


Recommended Posts

Hello, 

 

I'am making a Pin2DMD diplay myself for installing in a Stern Sopranos.

Everything is good until now, but I cannot find any information for connecting my Stmf32 in my pinball machine... 

A friend tell me I need ABSOLUTELY a shield for working in a real machine... I never find this information before. Is it true ? 

 

If it exist an another solution can you give me some informations ? 

 

Thanks a lot ? 

Sorry for my middle english, I'm from Belgium ?

Hi,

 

Today I've soldered my new Shield,

When I put it in a real machine I've no display... :-(

I don't understand, because 5Vdc is present everywhere, even on the displays.

The STMF32 has a green fix led, and blinking red led.
It has no SDcard on it, still not activated.

 

When I've tried the display out of machine with Dupont cables, everything was ok,

So I'm pretty sure it's a mistake with the Shield, But I don't know What...

 

Can you please help me guys ?

 

Many thanks  !

OK Lucky1.

Things seems to going better in better, 

But...

I cannot use Pin2DMD.exe...

It seems to doing nothing. Or I've an error window open when I push save config.

So, I've configured my display via Menu

It seems to be Ok

But Now, How am I supposed to add colorization file on MicroSD card ? 

Can I copy on it manually ? Or I absolutely need to use Pin2DMD.exe For this job ?

Many thanks ! 

Have a nice day ?

Hi, 

Today I've tried again to put my display in my real pinball machine, and it still didn"t work. :(

I don"t understand why I've no picture... Everything seems to be ok.

BUT, if I power the stmf32 with USB from my computer, and not via Shield, I've got picture !

I can see attract mode in my Pin2DMD in my real pinball.

But if I plug off usb cable --> The screen continue to operate ! 

But I absolutely to plug my USB cable to my computer One time for make it operate !

If I go to diagnostic, I can see Plug 11&17 Closed. What does it mean ? 

 

Thanks a lot.

Hello Guys, 

How're u ? 

First some photos of my montage

What do you thing ? (My first time...)

BUT, 

I've some issues (again, yes) with the display.

Now, I don't really know why, but it's very very glitchy compared to when I've tested It without any screw, ground etc...
It's really make headhache... Take a look

What can I do for it ? I've tested my 5Vdc supply, and I've just 5.00DC ... But, I cannot go less... It's minimum possible I think.

And, 

It seems to be, A LOT of frames that are not colorized, BUT, I'm using a FRENCH Display Eprom, 

So, Do I need to change it for an US Display Eprom to work correctly ? (I've got this idea, because i've seen some words stayed in english in my game...)

 

Again, Many Many thanks for your help guys ! 

Greetings ?

Ok, 

How can I do for lowing more my 5Vdc ? 

Add some resistor in serie with supply of Displays ? (Can you tell my how much resistor ?)

I use 5Vdc supply for optional board inside my backbox. Definitely no more use of High Voltage display board.

 

Thanks Lucky1

Yes, I've this

But I've found +5Vdc in the machine where not used, so I've taken it.
But, I think I will just add a DC-DC Converter, just before the display, just for lowering it.

With this

Do you think it's good ? 
Thanks ?

If you want to use the 5V from your machine you have to make sure it can supply up to 4A. 

I recommend to use 12V as a source and use the DC DC converter to set the voltage to 4.8V

Please measure the voltage before connecting the display.
