Hi,
This may be of interest for some of you people here, a friend of mine engineered this for me:
This a fv-1 based effect pedal, but with an atmega16u2 atmel used to emulate the eeprom. That way, the fv1 can acces 24 custom programs + the 8 built in ones. Of course, you could get more custom programs with a bigger atmel.
the fun part: to flash a program, I simply 'print' the .hex on the current preset. When connected to a pc with a usb cable, the atmel installs as a virtual printer this uses code found here: http://fourwalledcubicle.com/blog/2013/ ... ootloader/
here you can download the sourcecode for the atmel + schematics:

have fun

That is very cool! A number of people have emulated the eeprom with various micros but being able to just "print" a new hex to it makes it really easy to use and a very neat idea.

EEPROM Clock Rate?
Does anyone know (or has checked with logic Analyzer) the actual clock speed the FV-1 accesses the EEP at? I want to interface a PIC18F2539 to emulate the EEP.
I'm waiting for my order but would like to get finished on the board design s I'd really appreciate it if anyone knows (or can check!)

Is there a latin word for "Stage Fright"?
