I am looking for a way to monitor 54 a2d channels 0-5v. To begin with I thought about using an Atmega8 or 16 and some standalone adc modules like tlc1543 or adc0838. But with multiple adc's this becomes very complex, quickly. Maybe, I should use 5 attiny461 modules instead as they are possibly more flexible to use and I am more familiar with their architecture?
I only have experience with adc within the 1 avr module running by itself but in this project I will need to send all the values from the various channels to a master connected to an LCD. So I am not sure of the best way to proceed in terms of communicating protocols and modules. Any help would be appreciated!
