I have very simple project with electronic load for testing batteries and calculating their capacity. I use ATmega32's A/D converters to check voltage of batteries/voltage on load. I check every few seconds and I want to send it to my laptop, where all I have is an USB connector and make graphs with voltage history, either immedietly, or just save it somewhere and then send it all at once.
But I have no idea where to start or how to "search" properly. All I can find, when someone is asking the same question, is "buy this", but no one mentions how to use it step by step. I mean things like how to connect it with usb port, and what program to use to get received data into variables and make graph in some programming language. Everybody only checks with serial terminal. Of course i found something, but none of that is what I am looking for. Can you please recommend me some links with tutorials on this topics that you consider good?
Thank you for reading.
