[ts-7000] 20 ADC channels

["zebulon7482" <>]

Hello, I have a TS-7300 board and I want to connect 20 12 bits ADC
channels on it with 80 samples / second. How can I connect these ADC
with a minimum CPU load ? (SPI ? Async serial ? PC104 ?). I can use an
external chip like a CPLD to centralize all ADC signals.

I must use TI TLV2541 adc : http://www.ti.com/lit/gpn/tlv2541

In my user software, I only need the conversion results if one (ore
more) of the channels changed. Do I have to write a driver in the
kernel space ?
Do you have ideas ?

Thank you
