Picade button issue


#1

Hi,

I received (many thanks) and built up my Picade today and have an issue I think with the Picade controller board.
The two left side buttons are not being detected. I initially thought there was an problem with the wiring
but have buzzed out the buttons and the interconnecting wires back to the connector and it all checks out.
I can detect the press on the screw tops of the board as expected but no keypress is sent.

Since I wasnt sure what keys they should map to I connected just the board to the pc, but again no
response when pressed. This was the same as I saw trying to set them up in EmulationStation.

I reconnected the wires twice to make sure and the connections look fine, but no response from the Picade board.
All other buttons work as expected.

Anything else I can try?

Cheers,
Dave

Ah, having just watched the video I see that I missed that these map to the volume. So I guess not expected to send a key press. My bad.

If you don’t care about volume control, and you’re familiar with the Arduino IDE ( it’s not too complicated ) then you should be able to replace the software on your Picade PCB with a slightly tweaked version that maps the volume buttons to key presses.

When I find the time, I’ll produce a Sketch ( the Arduino lingo for an uncompiled program ) which has this already setup.

This could be useful in certain scenarios… although I’m not sure what those might be!

I did see an example that would remap them in the kickstarter comments here that looked straight forward. I just wasn’t convinced that I haddnt made a mistake during the build. I noted that someone used one as a CTRL to allow modifying another botton press for access to emulator options which sounded. useful. I just need to label them up for my kids otherwise I’ll have support issues :-)

Just came on forum to ask same question! Thanks for working it out for both of us!

The new firmware, if you’ve got the know-how to compile it in the Arduino IDE, has some very clearly labelled instructions for remapping the volume buttons: https://github.com/pimoroni/Picade-Sketch/blob/master/Picade/Picade.ino

We’ll work on a guide to modifying and installing this firmware soon, it’s easier than it looks!

This could be useful when emulating a Pinball machine, mapping the buttons left & right to the flippers, giving it an excellent pinball experience :D
