I recieved my kit yesterday and started to put my megadrum together. I got the PCB together hooked up the lcd and wualllah. I Had success so I unplugged my usb from the back of the pcb. The next time I plugged it in I got blank boxes. I am not very good at reading schematics so when it came to the keyboard I had a hard time wiring it up. I could use alittle help and please be more specific than pointing me to the schematic as I said before it doesn't seem to be helping.
As it stands now I have c1 chained to all 4 buttons and then I have the other 4 in there respective homes according to the diagram. Pleas help me in getting this problem resolved I really ancious to see what all the hype has been about.

Is it a kit with 3 yellow coloured boards?

How have you managed to solder everything together and yet have problems with the keyboard wiring, the simplest part of MegaDrum?

I dunno. I work well with pictures I guess... Its my first time working with schematics on anything. It was synthax version 2.7

My guess is that you accidentally entered bootloader and erased MegaDrum firmware.

Kewl,

I figured it out and I just updated the firmware and I am Up and running. I did get the keyboard right also. It was just weird how all of this happened. Now onto stage 3 the outputs...
