In this file, I will introduce the environment that I used, including the software and hardware environment

The equipment:

Microcomputer: ESP32-C6-DevKitM-1 *1

Amplifier unit: LM358 * 2

PC: LEGION*1

FPGA IDE: Arduino IDE

Multi-resistance and multi-line

(Notice: I only consider the 44 matrix for simply show it's working principle, of course it can be expanded into 2020 and so on)

test tool: different types of needles I also uploard the testing video: https://www.youtube.com/watch?v=6qERZ66b7y0 in this test, we use our robot arm and our fingers to verify it's valiation.
