DEV QUESTION: Ok, second one for the day. I have one more unit that BTN2 is not working on… at ALL. I can´t go to the meny, i can´t do anything. Checked all components, reflowed all the soldering points.
Any hints?
I will pull out the button to see if it is the culprit, but troubleshooting os not my most developed skill. I can handle eagle reasonably well but are there any things that i should look at first?
Any test program that i can run, and how , if so, do i use it?
When i press the button, where should i measure “someting happening”?
Thank you, i will check the suggestions. Great with testing possibilities, i just haven’t done it before and don’t have a slightest idea how to even begin. But i will try and do as you suggest.
Regarding the peering-issue i mentioned a few posts ago, i tried the sdram-test first with a unit that i have no problem with and get this… and nothing else. Waited 15 minutes, no other happening. Ok i presume?
Thanks for that @nicoj, i obviously have something not right in the setup for testing; will walk through everything to find what differs in my setup. This is getting annoying!
Just a quick note to say thank you for all your time and energy in making this project happen. Really enjoying learning the Megacommand, albeit slowly!
Can I ask what might be an obvious question? I’m trying to access the step sequencer for the Analog Four/Ext Midi
From the manual: To enter the PolyStep edit mode: Enter the MD Step Edit mode by pressing [PageSelect + Trigger 5]. Then Press the [Save] button to enter PolyStep Edit Page.
When hitting save in MD Step Edit mode I only seem to be able to engage REC ?
I am unable to access the PolyStep Edit Page.
checked, orientation is good. I always follow the marks on the board.
This one has the lower left pushbutton not working; no reaction at all.
When i run the button test all buttons except this changes from 1 to 0.
But i am unsure if i do the testing right, i follow instructions but somehow it feels like i´ve missed some step in setting it up for testing. I need to read up on the procedure again. You´ve seen the SRAM test procedure… well, on the first picture in my message above that unit is working perfectly but all that shows are those two lines and then it stops.
I have only connected it to the computer via USB at the time, verify is fine and upload too. Anything else i need to do for testing purposes?
Scrambled text in the “Serial Monitor” generally means a serial communication problem between PC and the Arduino 2560. This usually happens when the baud rate is set incorrectly, but I see you are using the correct 9600 baud.
You could try swap the Arduino for another and see if that resolves the problem?
Mmm, I don’t like that much this way to solder IC’s directly to the board for through hole…
I need to check once I get the components, perhaps the display can be placed too via socket, encoders don’t need to be placed all the way down, they can be tightened with the nut to the case…
the only thing is about the pushbutton height, they can be lower than the higher space if sockets are used.
Need to check if it is fine to use a “1S” model cap that come in different heights (is the one used for Ornament and Crime eurorack module, same manufacturer) instead of the “1D” cap model that has only 1 height option. The push button should be the same.
Of course I’ll need to make a new case, time to approach 3D printing.
