omnitek Posted February 15, 2013 Report Share Posted February 15, 2013 Hi everybody, I'm new on this site but I would like to have some help for troubleshooting the Midibox Sid V2 that I've just builded. It's a basic unit with only a core module and an audio module using the 8580R5 chip. So far the communication is good between the computer and the Midixox Sid but there is no sound coming at the output. I've run the mbsid_interconnection_test_v2 but it's seem there is no communication between the core module and the audio module since the voltages on the Sid chip don't change. Any help would be greatly appreciated. Thank you! Nick Quote Link to comment Share on other sites More sharing options...
Janis1279 Posted February 16, 2013 Report Share Posted February 16, 2013 Hi, I do not know about your pcb sources. - I remember, on the Core board from Mike, I soldered 2 additional isolated wires for communication purposes, an additional cable between the CLK input of the SID and Core::J7:SO/PIC Pin #17 at least. http://ucapps.de/mbhp/mbhp_core_v3.gif - You need to recheck the connection cable between the Core module and the Sid module, too http://ucapps.de/mbhp/mbhp_8xsid_c64_psu_optimized.pdf Regards, Janis Reinholds Quote Link to comment Share on other sites More sharing options...
omnitek Posted February 20, 2013 Author Report Share Posted February 20, 2013 Hi, i bought my boards from AVI Showtech Smash TV. I connected the two boards as follow: Core J10 Audio J2 Vd Vc Vs Vs SO SO SC SC MU MU CLK CLK RC RC There is a MD pin one the J10 connector of the Core board but none on the J2 connector of the Audio board. I'm I missing something? Thanks! Nick Quote Link to comment Share on other sites More sharing options...
TK. Posted February 20, 2013 Report Share Posted February 20, 2013 Hi Nick, please check this schematic again: http://ucapps.de/mbhp/mbhp_8xsid_c64_psu_optimized.pdf There is no SC->SC connection But there is a MD->MD connection... Best Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
omnitek Posted February 20, 2013 Author Report Share Posted February 20, 2013 (edited) Hi, Apparently, the MD pin of the core has to be connected to the SC pin of the audio module like described here: http://www.midibox.org/dokuwiki/doku.php?id=midibox_sid_faq#how_do_i_connect_the_sid-module_to_the_core-module I uploaded the V2 hex file and now the Sid is alive and I have sound at the output. Thank you for you help! Nick Edited February 20, 2013 by omnitek Quote Link to comment Share on other sites More sharing options...
omnitek Posted February 23, 2013 Author Report Share Posted February 23, 2013 Hi, I have another question that might sound stupid but how to save a patch in the bank stick with the CTRL editor? Thanks! Nick Quote Link to comment Share on other sites More sharing options...
