Beginner project question!: DE0 Nano+temp sensor+save to file

FPGA are great for doing custom hardware like custom CPU, DSP, audio/video processing, etc..

Things like record temperature for x amount of time, and save the data to a csv file is a 2$ MCU stuff not a 40$ FPGA stuff

By the way you can do it with soft-cpu like NIOS II

To start some logic block like multiplexer, FSM, etc.. with VHDL o Verilog are great to learn FPGA
