I think i did well regarding the building of the midiboy since everything seems to work fine when booting.
Unfortunately i’m unable to upload a sketche into it.
Here is the log message
avrdude: error: could not find USB device with vid=0x16c0 pid=0x5dc vendor=‘www.fischl.de’ product=‘USBasp’
avrdude done. Thank you.
the selected serial port
does not exist or your board is not connected
I think my mac doesn’t not recognize the usb device
I you think about something that would be great !
