Hi
I'm a little new to these kinds of subjects coming from a physics backgroung with no experience.
(i've toyed a little in my free time with very basic projects but nothing serious).
I'm working on a project and i'd like to ask (firstly) feedback for a structural way of understanding things. Thats why some questions may seem a bit dumb but im asking some of these to be sure.
I will use:
Αn "Arduino Uno R4 Minima"
an ADC LCT14071 (i wont be using the buit-in adc´s of the arduino)
a signal generator AD9833
a sensor (handmade)
The goal is:
connect the sensor with the adc (so the adc reads the sensor) and the adc with the arduino (to send the data). Also the signal generator (connected to the arduino) will send excitation signals to the sensor.
I will be using SPI protocol
My (first) question(s) is:
-
When using the electric components, is it just an aseemly of this components or do i have to take into account reistors, capacitors etc (because of the recommended values of voltage and current ).
In the second option, should i start and use the reccomende options in the schematics of the datasheets (and modify them as i go) or should i start from scratch -
Considering the fact that i connect everythng accoerdingly and i have/write a code (which i know i easier said then done) how can i modify the speed which the data is tranfered? (this is the heart of the project. Managing to adjust data speed at specific values)
i tried to ask this questions as generally as possible so not to bombarred anyone with all my question. I think this well be a good starting point.
(3. truth be told i have a third question but i think its a bit more specific so i didnt want to burden the other 2 question, so i ask it seperately foe anyone that my know. How do i do subsampling?)
Thank you very much in advance
