MIDIbox SEQ problem

MIDIbox SEQ
1

Hi there

I have built a MIDIbox SEQ, same as TK´s. But i toke the fast way and got my core from SmashTV’s Website with all components and with a PIC and bootloader preprogrammed (PIC ID header: 0000000000000000).

When i start up MIOS Studio all is working just fine, i get a heart beat form the core (timestamp 1580077000 us: sysex message: F0 00 00 7E 40 00 01 F7) and its ticking ever 2 sec. I upload setup_mbseq_v2.HEX and hits the start button and away it goes without any errors and its tell me in the ends that it is complet. (all checksums are ok). When i restart SEQ the display is empty  :frowning:

I have seen on the older core that J3 has to be strapped, but this core card doesent have a J3.

Im i missing something here or im i just plain dumb??

Hi-

Would it be better to upload the MIOS itself before uploading the Application?  :wink:

Well i solved it, but there is something else inseed. When i uploaded setup_mbseq_v2.hex and reboot the SEQ the first display is just showing NOIX  IX NOIX NOIX NOIX NOIX NOIX and the second one is working fine. I use two GTC40021 displays, and yes its set to two 2*40.

Any ide here?

Thats a strange effect, I never heard about this before. What happens, if you press a layer or the Edit button? (this would re-initialize the screen)

Hi

Well its changes some part on the display, but it is the same “crap” that are showning. All the buttons and rotarys are working, its just the first display thats not working correct.

If you swap the connections over (make the 1st display the 2nd one, and the 2nd one the 1st) which one fails?

You have to change the encoder type in mios_tables.inc
