CPD interfacing with BMS
« on: February 22, 2021, 05:53:20 PM »
Hi!

I got my hands on a CPD and now I need help with hooking it up with BMS 4.35. I installed lightingtools CPD software which lights it up when I enter BMS, but no data is being extracted. Just a static screen.

I also don’t know how to hook it up to a Pokeys (other?) so that I get the buttons and backlighting functioning.

I’m a rookie on this interfacing stuff, so need help.

I’ve got the same thing. CPD Display working and buttons and rotaries wired to two BBI- 32 Bodnar Boards but no data being transferred or read from BMS. I’m running Lightnings F16CPD v 0_5_8_1 x86.

Hey @VanZeb

I have the same problem as yours. 2 years ago I have bought the CPD from one of the forum members. In the topic below  :

http://www.viperpits.org/smf/index.php?topic=7382.30

I have asked how to connect the CPD with DB37 breakout board to Leo Bodnar interface card (BU0836X)...so far I didn't succeed as I haven't got any button response...It would be great if someone could post some pictures how to connect the wires to the DB37 breakout board and Leo Bodnar and/or Pokeys.

Today I tried to connect the Pokeys 57U board (only button matrix) and still nothing..it is so frustrating and annoying when you don't know how to solve this problem anymore  :stupid:....or I just bought broken CPD...

I don't know much about the CPD, but maybe this pinout will help if it's the same unit Crease-Guard used to make.

I know absolutely nothing about that CPD.

But have you tried just connecting another button to the board to establish if the board is functioning correctly? If the board is functioning then obviously that is one problem you can delete from the troubleshooting list.

With the help of Mr. @Romanski I have created matrix in Pokeys....so far lets say 50% of buttons are working and the other half doesn't, seems like a problem with the matrix or wiring...

I just compiled the latest version of the CPD from Lightnings code and it seems to be working fine.
Which version of his CPD are you using and which version of BMS?

I’m running Lightnings F16CPD v 0_5_8_1 x86.  BMS 4.35U1. Looks the same as your display and buttons , rotaries and toggles all function just not getting data from BMS.  Screen is froze as your picture depicts.

The version I compiled is 0.5.9.0, looks like the setup file is not updated on his github.
