for more USB Compos i start with USB MIDI ...
i have found a lot of Descriptor at Microchip Examples...
i modify a little for MIDI USB ..
The Strings can be change if someone need this...
..
Now i will start to "learn" in Flowcode how this USB i can create as a USB Compo for USB MIDI..
for later Time.. i will go on ..;-)Can someone teach
)) or... this as example make as a How To .. will better
)))))) I do not know how the Descriptor Tool for FC is use..
..
Code: Select all
#Define DSC_DEV 0x01
..
..
#Define EP0_BUFF_SIZE 8 // 8,16,32, or 64
Code: Select all
