sammichSID Doesn't boot up to main screen after upload firmware. CS not enabled!

Hi there,

I’ve build a sammichSID for my friend long long time ago. Recently, he brought it back to me because it wasn’t working. I think the MCU is corrupt due to some reason and I am not able to upload the firmware anymore. I have four PIC18F4685 that I brought 2 years ago. I was planning to build a MB-6582 but I never have any spare time, so I have decide to use one of this IC inthe sammichSID. The MCU I got has the device ID 0 - 3. I have plug them into the sammichSID and I found only the PIC18F4685 with device ID 0 is working. All other PIC18F4685 eith device ID 1 - 3 is not working. I can upload the firmware in there but it doesn’t go to the main screen after reboot. The screen shown that “CS not enabled” . Does that mean device ID 1 to 3 can not be use in the sammichSID ? Any way that I can change the device ID back to 0 ?

Only the PIC with the ID0 displays anything. The software checks for the ID and if it’s not 0, it doesn’t even try to do any CS stuff, since it assumes it’s a slave PIC. So to use a PIC with device ID 1..3 in a sammichSID you’d need to download the change_id app from ucapps.de and use it to change the PIC ID first. Then reupload the mbSID app.
