4A CNC regulated power supply reference design (schematic diagram + program)

Overview

A good CNC power supply: two outputs: 1: 0-30V/4A 2: 5V/1.5A (fixed output) voltage resolution 0.458mV, current resolution 0.076mA voltage step 0.0073V, actually using 0.1V step adjustment. The reset circuit is compatible with both 51 and AVR. You cannot solder all four components on. Just solder the reset circuit according to the chip you use!

This is a very frustrating problem. WinCE and Platform Builder experts please come in and give me more suggestions. Thank you!
I bought a FriendlyARM board, used VS2005 to develop a program to run on the board, and flashed the system to WinCE 5.0. The program development was also completed. Just when I thought everything was

Question: I originally used WinCE5.0 and could install a program, but later when the device was updated, WinCE was upgraded, and when I reinstalled it, I was unable to install it.
I used WinCE5.0 to install a program, but after the device was updated, WinCE was upgraded. When I reinstalled it, it could not be installed. I have been confused about this. The system mainly fixed t
Who has the relevant information about the motor soft start control board?
Does anyone have relevant information on motor soft start control boards? I am planning to transition to power electronics and start with thyristors. The first thing I will start with is the motor sof
Will the voltage of LM358 continue to decrease during actual use?
Hello everyone, my graduation project is to test the battery voltage of an electric vehicle. The basic circuit diagram is as follows. The input is 55V (battery voltage), and after the voltage is divid
