bemerritt Posted September 25, 2017 Report Share Posted September 25, 2017 (edited) So over the weekend I soldered up all of my boards (core, cs, Midi I/O, DOUT, AOUT NG), and am having trouble connecting the CS. I have spent hours reading old topics on the matter, but could use some help. First step, SD card is formatted and I have what I think is the right file in the right place. Connected the boards and get this https://farm5.staticflickr.com/4480/36644661203_97e4deb683_b.jpg I used jumpers just to make sure I had the correct pins connected. To J1 i get know response, on J2 i can get all sorts of response by touching the solder pands on the bottom of the baord https://farm5.staticflickr.com/4438/36644661223_97e4deb683_b.jpg While connected in this fashion, i get this in MIOS https://farm5.staticflickr.com/4465/36644591683_7cc7606127_b.jpg Which makes it looks like buttons are being pressed. Suggesting I have shorts. Looked at every joint under a microscope (I'm used to doing SMT work), and nothing there. Previous threads had called the resistor networks into question. Here is what i used, all showing 5 volts on the common pin. https://farm5.staticflickr.com/4488/37284805592_3cc8fe5e0e_b.jpg I also left these jumpers empty, which shouldn't be a problem https://farm5.staticflickr.com/4505/37314418261_9ef3876dbf_b.jpg Some other notes - Not all leds are soldered, i just did the 16 bi-colored ones - I defintiely connected the boards backwards, could i have fried my ICs on the CS? (have some new ones on order) So, any ideas? Anything to help troubleshoot would be awesome. Thanks! edit: is there an issue with having more than one picture in a post?

latigid on Posted September 25, 2017 Report Share Posted September 25, 2017 Please embed the pictures here so when the offsite doku goes bad they'll last at least as long as the forum does. You have the headers in backwards. They should go on the underside of the board. This will also allow you to put the panel on properly. Try to get the main CS working before connecting any other modules (DOUT, AOUT etc.). Quote Link to comment Share on other sites More sharing options...
bemerritt Posted September 26, 2017 Author Report Share Posted September 26, 2017 (edited) Well, that did the trick. Something as simple as mounting it on the front was something I hoped it would be, but is also rather emabarassing! Thanks for providing the second pair of eyes, I had tried way too many things yesterday and it was driving me crazy! Now the fun begins to get all of the different modules talking to eachother begins. Edited September 26, 2017 by bemerritt Quote Link to comment Share on other sites More sharing options...
