BankStick enigma

Testing/Troubleshooting
1

Hello everybody,

I’ve made a 8-Eeprom stripboard for my Seq, but it’s like nothing is connected to it.

The chips are 24LC512 from SmashTV.

It’s the same when I use other chips (from my MBSID, perfectly working there).

The board looks OK to the multimeter. No shorts, no isolated pins. The voltages are OK in each socket too.

The cable is OK: the IIC MIDI works well.

The Seq recognizes the chips sitting in the MBSID’s BS board (so well it immediately formatted them, erasing some SID presets :P). Because that board is also for PSU, I can’t try replacing it with the newly made board.

Tried building another (vero)board with just one chip: still nothing.

I think it’s an enigma… any help??

Thanks, Enrico

Have you tried to disconnect the IIC Modul and only connect the Bankstick?

What kind of coreboard do you use?

Yes, it still doesn’t see that board.

It’s a Core R4d from SmashTV, just bought together with the chips.

SCL and SDA were swapped in the schematic.

I hate myself.

>:(

But that’s Midibox too :slight_smile:

Be glad that there´s no enigma!  ;D
