As stated on the web Data acquisition (DAQ) is the process of measuring an electrical or physical phenomenon such as voltage, current, temperature, pressure, or sound with a computer. A DAQ system consists of sensors, DAQ measurement hardware, and a computer with programmable software. The first thing you need to do is to clearly define the problem, and what results you want. Once this is done and you have done some research so you are comfortable with your hypothesis it is time to solve it. Then you can look at how to measure the physical components such as time, temperature, etc. At this point you can determine what type of processing power you need and what computer will do that for you. This is not a 1 pass solution, you need to go through it many times until there is no changes. Currently it appears you have a solution looking for an answer, that never really works out in the end. There is a tremendous variety of data on the web about this and how to properly accomplish what you want to do. This response is to help you get started in solving your problem, not solve it for you.Good Luck & Have Fun!Gil
If I am trying to obtain 10kHz of 12-bit voltage (ADC) data in multiple channels (8 would be good, 24 would be even better) and store the data in at least 20s chunks what microcontroller setup (or rasberry Pi) do you reccomend?
