Hello folks,
I have - I guess it is another stupid beginners question - a problem in understanding.
Let's say I want to use a ATMEGA328 running with 16MHz and I want to combine this with another smaller IC, let's say an ATTINY 44V-10PU running at 10MHz. Will this cause problems with the communication between the both IC's.
I somehow guess so, but I really do not understand much enough about it to answer this to myself.
friendly greetings to everyone and thank you in advance for your effort

You haven't specified how you wish to communicate between the µcontrollers. I2C or SPI or something else?
I would not let the 16MHz to 10MHz confuse you. The communication protocols will usually handle communication speed!

Hi,
Right now, I can not specify, because I just don't know yet, which kind of protocol I prefer to use later. I guess that is depending on the case I am going to use.
Anyway, I think this answer is satisfying for me now.
thank you answering so fast.

I have never used an ATTiny, but according to the pinout drawings, they are capable of both I2C and SPI.
So I don't see any problems with communication between these two µcontrollers.

Thanks, that is all I wanted to know. At least I feel better with your message. For now, even I can not say if I ever going to use this guy, but last few weeks, I read so much information about the whole thing arround the Rasperry - I just used that one for watching movies - and the Arduino - I never thought I could get aquaintant with this one.
Nevertheless, as I say, I read a lot, I searched a lot and now I am going to figure out, what can I do with all that, and it already beat me down.
Thanks to you, I am going to try more.
