NFC fingerprint wireless desktop boot stick

Overview

1. If the fingerprint is entered correctly, the OLED will display the power on and fingerprint ID.

2. If the fingerprint is wrong, OLED will prompt to compare again and display that the computer is shut down.

3. If the NFC card is swiped correctly, the OLED will display the power on and fingerprint ID.

4. If there is an NFC error, OLED will prompt to compare again and display that the computer is shut down.

Compare the information through arduino uno/nano, and pull the corresponding I/O level low. The I/O level is read by esp01s and sent to the receiving end in the same LAN through the TCP protocol, and then a low level of more than 500ms is input to the Power pin of the computer motherboard to start the computer.

How to realize adjustable pulse frequency, pulse width and amplitude?
I plan to use TIM+DAC to achieve this. Use TIM2 to adjust the frequency and generate a square wave. TIM3 is a single pulse in slave mode, adjusts the pulse width, and is triggered by TIM2.This step is

Why are there more posts about STM microcontrollers in the forum but fewer posts about LPC microcontrollers?
Why are there more posts about STM microcontrollers in the forum and fewer posts about LPC microcontrollers? Is it because STM microcontrollers are used more than LPC microcontrollers?If I want to get
Could you please recommend a simulation software for Modbus slave simulation, besides ModSim?
I am working on a Modbus host program recently and need a software that can simulate the slave. I am currently using ModSim, but it cannot control the response delay. Does anyone have any good softwar
