You read the Documentation provided on the website starting from http://www.megadrum.info/content/what-y ... d-megadrum

I read the instructions, but all are to UPDATE the ATMEGA with bootloader, but nothing explain how to install for the first time the program in the ATMEGA (my ATMEGA is new, buy on mouser).

I make new test today : there is progress !!! YES !!!

I've got errors but less than before :

Read it all carefully.

It is ok, your PIC is programmed.

My pic is programed ? But when I disconnect the USB and the ICSP, and when I reconnect the USB, my computer don't propose to install driver. When I do the first programmation but with the wrong hex file, computer operate correctly to propose installation of the driver.

I do a dump of the pic i read with winpic. See attached file. When I compare this file with the original hex file, I haven't got the same information. So I'm not sure that the programmation success.

sorry for mistake...

Drivers are already in OS so it doesn't have to install it.

Looks like you don't like to read. Anyway, read MegaDrum FAQ. Read it before posting in this forum!

Yes, but when I connect megadrum usb to my computer, I haven't any reaction. It don't find I connect the Megadrum, than the first time it works fine with the wrong hex file. So I supose.

Sorry for the anwers there are in the FAQ.
