My first EDA design - induction voltage pen EDA

Overview

This induction voltage pen is a small device designed and produced based on the principle of signal amplification by triodes that can detect whether there is voltage near the socket. It is not only simple in function, easy to use, but also compact and beautiful.
This is the first result after initial learning of EDA. I hope you all like it!
By the way, please wish me a smooth final exam on the 20th and good grades! ✍✍

Getting started with PIC24. Let's get some experience first
I have never come into contact with PIC products before, but now I have a job that requires them. Let me learn it~:) I was very inspired by sjl2001's experience post. I have sorted out a few small que
Please help!
Hey guys, my T1CNT can't count automatically in CCS environment, but my enable bits have been set. The program of initial event manager is as follows:void init_EV(void){EvaRegs.T1CNT=0; // The initial

Can two devices communicate using the Jtag interface?
I am working on a project recently, combining two existing devices. The two devices' CPUs need to communicate, and all interfaces have other uses, leaving only one Jtag. Is there any way to use Jtag f
