I’m not good at programming but this guy writes it works. Or is there already a working firmware for it ? I need to get the clock from the midiout of my dj-mixer to my laptop (which just has usb). Its to syncronise to the running vinyl. I dont wanted to buy a interface.
cool that your MBSID is already working on your first forum post!
I’ve cancled the PIC based USB project, but if the guy writes that his firmware is working, I would propose to try it out. Since I’m using the 2x4 MIDI router, I’ve no personal need anymore for a USB solution (I prefer direct MIDI routing without the need for a PC in order to reduce latencies)
Just bumped into this forum (BTW, a lot of interesting things!) while looking for a simple MIDI out USB DIY board.
(I am looking for simple and low cost solution to midify an organ pedalboard that could be plugge directly to a PC USB port)
I understand there are still issues with the UART on the 18f4550 but I guess it should work perfectly for MIDI out through the USB port (would it also work with the UART when doing MIDIout only?)
Would it be OK to re-use the USB part of the code you have developped for the 18f4550?
For your “simple” interface, NUMBER_MIDI_INTERFACES should be set from 5 to 1 in usbdsc.c (by default, it is assumed that 4 MBHP_IIC_MIDI module are connected in addition, resulting into 5 MIDI In and 5 MIDI Out ports).
IIC_MIDI_MAX_NUMBER should be set from 4 to 0 in iic_midi.asm, otherwise you need to add some additional pull-up resistors to the core (I guess the RA0..RA3 pin + RD5) in order to avoid random effects.
I read about the eusart bug. :((
