Problem with Analog Buttons #249

Closed thomasf78 closed 9 months ago

thomasf78 commented 9 months ago

Hi Igor i have problems with Analog buttons on OpenDeck M (Board Version 2.2. // Firmware 7.6.0 - but also on older Firmware Versions).

I started the project without connected Buttons and activated the Analog inputs - as in wiki manual recommended.

If i connect the buttons (EC11 encoder buttons, and simple PCB Board Buttons) i have the same issues:

There is a pattern recognizeable. e.g. Button 74 (Analog Input 10) - OK Button 75 (Analog Input 11) - not OK --> I receive messages from both Channel 11 and Channel 10 Button 76 (Analog Input 12) - OK Button 77 (Analog Input 13) - not OK --> I receive messages from both Channel 13 and Channel 12 Button 78 (Analog Input 14) - OK

At this point i havent connected Channel 0-9, but activated. There i will add some potentiometers.

Can you give me a hint what i am doing wrong. Attached a Video with the Console Log

Thanks so much Best Thomas

I think you're confusing terms a bit here. Buttons aren't sending wrong channels, they are sending wrong MIDI indexes. Can you post how you have those buttons wired up?

thomasf78 commented 9 months ago

Hi Igor, thanks for your fast reply. Sorry about confusing you.

I wired the buttons in the following manner: Button 1 - Analog Port 10 (A:+ // B: Signal) --> AH2 Button 2 - Analog Port 11 (A:+ // B: Signal) Button 3 - Analog Port 12 (A:+ // B: Signal) Button 4 - Analog Port 13 (A:+ // B: Signal) Button 5 - Analog Port 14 (A:+ // B: Signal) Button 6 - Analog Port 15 (A:+ // B: Signal) --> not shown in the video

My plan is to do this also on AH3 for six more buttons. Not realised yet. Just for testing purpose i wired up a button on: Button x - Analog Port 31 (A:+ // B: Signal) --> the same behaviour --> MIDI Index 31 and 30 sent.

I hope this is helpful. Thanks and best Thomas

Did you use the resistors?

thomasf78 commented 9 months ago

hi igor. shame on me. i didn't. how i could forgot the important pulldown resistor. thats the reason why i got wrong signals. thanks a lot. i will change my layout. many thanks. i will inform you if it works. best thomas

Hi igor, thank you very much for your support. you can close the task.

@ everyone who is so stupid like i was, and has forgotten the pull down resistor -- here is the solution. :-)
