At present, most of the common wireless remote controls on the market are four-key and twelve-key, mainly used in car anti-theft systems, home anti-theft systems and remote control toys. These applica...
The effect that rt hopes to achieve is to execute business logic once every 12 hours, and enter sleep mode at other times. Therefore, stopmode+HAL_RTCEx_SetWakeUpTimer_IT is used here to achieve this....
This is an old and relatively effective method, suitable for testing small resistors with medium precision. Of course, since small resistors need to be tested, the bridge must be a double bridge with ...
[color=#333333]In digital circuits, all unused input pins must be connected to a fixed level, connected to a high level or grounded through a 1k resistor. [/color] [color=#333333]1. Function of resist...
High efficiency and low standby power consumption are two major challenges in today's switching power supply design. Resonant topology or LLC topology is becoming increasingly popular because it ca...[Details]
A single-chip microcomputer is also called a single-chip microcontroller. It is not a chip that completes a certain logical function, but a computer system integrated into one chip. In general, a c...[Details]

At present, most lighting equipment still uses traditional energy for lighting. Making full use of solar energy as the energy supply for lighting equipment is of great si...[Details]
Overview:
This paper introduces a method of connecting a CAN-bus network with Ethernet to form a medium-sized remote monitoring/data transmission network.
CAN (Controller Area Network) is ...[Details]
Many battery-powered systems require a visual indicator to show when the battery needs to be replaced. LEDs are commonly used for this purpose, but they consume at least 10mA of current. This con...[Details]
With concerns about the growing energy crisis, motor efficiency has become an important and timely topic. This is because motors use 63% to 70% of the electricity produced in the United States and ...[Details]
