Geir_Helgi Posted February 10, 2011 Report Share Posted February 10, 2011 (edited) Ok, I've been sick the last few days (there's a flu lurking around) and to make good use of my spare time I decided to whip out my Sammich (it's been in storage since I moved a couple of months ago)... First of all; The voltage readings are fine (all of them). The sammichCSTest.hex worked fine (all the LEDs lit up like in Wilba's little flash video). The OS uploads/installs fine. I could even transmit the vintage presets to the Sammich (and I see the name of the first patch). But none of the buttons work. Strange, eh? Help a brother out! (ps. I only have one 6581 installed, shouldn't matter and I've got a perfect regulated 12V PSU) Edited February 10, 2011 by Geir_Helgi Quote Link to comment Share on other sites More sharing options...
sylwester Posted February 10, 2011 Report Share Posted February 10, 2011 First, I'd check the traces connected to the shift registers (74HC165) and the solder points. If you could make some close-up pictures I could check the it visually. Quote Link to comment Share on other sites More sharing options...
Flemming Posted February 10, 2011 Report Share Posted February 10, 2011 (edited) So, it worked before or what?? And the encoder works?? I once experienced that my CS did not work at first power-up, but then i quickly remebered that i didn't solder the header pins on the CS, only for the LCD :wacko: Edited February 10, 2011 by Flemming Quote Link to comment Share on other sites More sharing options...
Geir_Helgi Posted February 11, 2011 Author Report Share Posted February 11, 2011 Ok, I'll check those traces.. The only dodgy things on the board (lower board) are the heat-sink solder joints, because I messed it up and had to use the upper surface points. It wouldn't hurt to know what the continuity/ohm meter should read on that part of the pcb :rofl: It didn't work before, the encoder doesn't work either and none of the buttons work :sad: Both headers are soldered.

Geir_Helgi Posted February 19, 2014 Author Report Share Posted February 19, 2014 WOW! Just found my old sammichSID which wasn't working, resoldered some nasty newbie mistakes and thorougly checked all the points (according to the build guide) Still nothing happened :( Then I found an old thread where somebody (like me) was so eager to get his SID sound up & running that he accidentally put some ICs in the wrong place!! I checked those and *bam* there was the problem that had me running in circles all that time :D Now I'm sending an arpeggiator into my Sammich (with a 6581) and it sounds GREAT :D Can't wait to start using it, loving it and tweaking it :D Thanks everyone! Happy 2014! Quote Link to comment Share on other sites More sharing options...
