Sequencer done :)

The Sequencer is finally up an running in his new Acrylic case ... Todo's ... adding a 5 Volt external PS for the STM32F4 instead of USB-cable and building the Frontpanel for the Line-Driverstuff

Line Driver test

I ran out of 15k resistors for the AOUT but still ... Line Drivers connected and all works fine ... well all sockets get 5 V where they should .. still a bit confused with the ribboncables .. hope S0 and S1 are not switched ..

Wilba nearly done

The SIL couldn't be delivered and I had to do the LED twice because of the round buttons, but progress is visible :)

PICs programmed

After some configbattle with the Pickit2 clone (Vdd has to be 3 or 4 volt instead of standard 5) all 4 PICs for the of the Quad IIC are programmed. But I had to notice that at my 2 Midi IOs only 2 LEDs do blink on startup :( although 4 days ago all worked fine. I think it might be my SD card (I took a very old one from my ) or the the slot, so the hexfile is not read completely ... mor debughing soon ..

Midi IOs done

Anogher little step further to my baby .... had a bit of panic cause the boards didn't work at first, but the only problem was, that I connected J11E to J2 of one board instead of J1 .. had one connection cable cramped wrong ..

IT'S ALIVE

I always wanted to say this too ... Still some troubles with the MBSEQ_HW.V4 file Some functions are not supported by the MIOS .. at least that is what zhe MIOS Studio tells me. Like LED_move, LED_JAM_LIVE, LED_LIVE and some more, plus the BUTTON too ...
