Hello
I think I have most of the code in place. I will have a look at this tonight and see if I can it together so it compiles and runs correctly.

Hello
I have started the MIDI interface driver now and it looks promising. I have a custom component program complete with a MIDI USB descriptor that compiles anyway. The problem im having at the moment is that a lot of the low level usb midi endpoint communications is currently written in assembler in the example im using so its going to take a little while for me to dig through this and make it Flowcode friendly.
However good progress for one night
For now I suggest you have a play with the existing USB components they are quite fun to play with if you have the ECIO or any USB PIC microcontroller.

I am playing with the USB components
you right.. it's fun and it is worth it to buy Flowcode.
Thank you..

I found USB MIDI Devices 1.0 on USB.org

it looks so complicated.....

Hello
Thankfully I found a Microchip example and the code is already fairly similar to the Flowcode USB code so thats most of the complications taken care of. However as I previously mentioned the interface code is all in assembler (DOH!!) which is causing the current hold up. I should get some more time over the next few days to get this all tied up and working so please bear with me.

That chears me thx...
I was using default RXINT in flowcode v4 but I am not getting Interrupt for Ecio40p....
what should I do?

Have you tried SALVO RTOS?

No not personally but I have tried the "NOVO" RTOS that comes with the BoostC compiler. There is also a good RTOS available for AVR via the GCC compiler.

i was just looking for usb driver until you can help me with the usb midi...
Can you tell me how far you've done so far for that midi interface ?
