Low-cost 2.5KV USB power isolation solution (schematic + BOM + gerber, etc.)

Overview

This is a low-cost isolation achieved through a power transformer. Since the transformer is more convenient for AC isolation, but DC is not suitable, ATtiny412 is specially used for control.

Newbies learning WINCE
I am a novice and am learning WINCE for the first time. I wonder if you experts have any good books and materials to recommend so that I can get started quickly?
VB.NET serial port receiving data is incomplete
I am developing winsCE with VB.NET. When using serial port communication, I use the code n = Me.SerialPort1.BytesToRead If n > 0 Then Me.SerialPort1.Read(shuju, 0, 30) end if The array shuju I defined
Wince's real-time response capability
Let me first talk about my needs: The frequency of CAN bus receiving interrupt is about once every 20ms. After WinCE receives a CAN bus receiving interrupt, it processes some simple calculations (the
