Hi,

Would it be an idea to have a separate processor that deals specific with just the Panel ( polling the keys, driving the hex digits and the leds + detecting adjustments any panel pot?

The idea is that the separate panel processor ie MSP430/PIC32 is responsible for detecting any change on the panel and it will signal this through one may be several interrupts (different prio's) to the main processor which than will fetch the "cause" of the interrupt via a SPI interface. So the MSP430 or ie PIC32 panel processor acts like a SPI slave unit.


This idea suggestion based on the software OO design principle: tight cohesion loose coupling principle and the following diagram :

Question: anybody knows why these read micro P1 and P2 are used for? During production testing?

Cheers

ps: don't know if this is the right group, this is my very first posting....

As fas as I remember, the G2 has a chip for just that. A non-extended synth has 5 processors. I could be wrong though, it's been a while.

you mean on the main PCB itself? because (see link above) the control panel has some circuits/logic build in

Sorry, I should have checked that link. I like the first diagram best Laughing

I'm sorry, that's all I know.

Oh, I just saw it now: Are you talking about the Electro 2? Then you ask in the wrong place. This is the G2 forum. What I said is about the G2.
