Still confused... Could someone please explain how to program the PIC? I have only one SID, a 8580. I has a 2x40 LCD, and 10 buttons + 1 "menu-button" + rotary encoder. First I have to burn the bootstrap loader. I don't need to do anything special to the mios_bootstrap_loader_v1_1b.hex, right? Secondly I have to install mios_v1_7.hex (or greater?). I can do this by using MOISStudio, marking Wait for upload request..., reading the mios-file and turning on the MBSid. Do I have to do anything with the mios-hexfile? I have done these two steps, and I think that everything is working ok. But what to do now? Should I install main.hex or setup_8580.HEX or both? Do I need to reboot the MBSid between the installations? When these installations are done, is that it? Will it work then (well, at least if I haven't done anything else wrong...)? Please, please, please help me! :'( Best regards Niklas

Everything seems to be ok.... A question about the 10k resistor that isn't needed... Should I (as I have done) just leave it, or should I replace it with a bridge instead? Another question about the chrystal, whichs seems to be correctly soldered. I use a 1.0MHz IQXO-350C... maybe this wasn't a right choice? /Niklas

Hi, This morning I finally had the time to finish the basic steps of the MIDIBox SID. I have programmed the PIC with bootstraper and I easily transferred the MIOS (main.hex) and the 8085 application (setup_8580_without_cs.HEX). Full of expectation I started the sequencer and heard... nothing... :-( Maybe something didn't quite work out with the programming... Should I restart the MIDIBox before transferring the application? By the way, how does the PIC differ between MOIS and the application? After some troubleshooting I found that I had switched the MD and MU connections on the Core-card so I fixed this, but there is still no sound... Can anything have been damaged by this mistake? Instead of the BC547 I use a BC550 which has the same pin configuration (please correct me if A'm wrong). I will add, when this is up and working, controll buttons and a 2x40 LCD. But first I want to hear a sound from the SID. Best regards /Niklas

Ok. Correct me if I'm wrong. I should burn the mios_bootstrap_loader_v1_1b.hex to the PIC. Then I can use the bootstraper to program the PIC for the SID(?) via midi. But still, could someone please explain the different hex-files, actually the main.hex and the different setup...hex files please. Thanks for your help! Best regards /Niklas

Sorry for bothering you with a newbie question... I have just finished the core module and the sid module, and it's time for programming the PIC so I can continue with the testing of it all. I have never programmed a pic before, but I have a USB pic programmer from kitsrus, using the program MicroPro. I downloaded the MIOS, midibox_sid_v1_7a.zip, and unpacked it. I found, as you all know, five hex-files. One is called main.hex, and I assume that this file is necessary, and there are two files each for the two SID-versions. I will make a small control surface, so I guess I should use the setup_8580.HEX (since I got a 8580). Am I correct? Is it possible to use two hex-files to programm a PIC? Could anyone help me out , give me some advise or guide me to the right place? Best regards /Niklas ???
