IC card access control card reader based on RC522/WS1850S

Overview

According to the official manual, RC522 and WS1850S can be pintoped. This project is based on the WS1850S and has been verified to have no problem with the function.

The microcontroller and the module can be connected using an FPC flexible cable (10pin) or a network cable.

All original parts are made of Jiali adhesive patch components, and basic library components are chosen as much as possible.

Why choose voltage mode control for fixed frequency pulse width modulation of power supply?
There are two types of fixed-frequency PWM control: voltage mode and current mode.One of the main differences between voltage mode and current mode is the ramp input to the fixed frequency PWM compara
