I made a zigbee module and received bytes from the serial port. I found that if too many bytes are transmitted (139 bytes at a time), 20 bytes will be lost. I reduced the bytes and sent them again. Wh...
A few days ago, a friend asked me that there are two versions of 18b20 in the market, c3 and c4 (I am not well-informed and have never heard of them). He originally used the c3 version, and later his ...
Hey guys, after the ZigBee coordinator goes offline, the nodes will keep searching for the network, so the battery-powered nodes will run out of power very quickly. How can we save power and search fo...

1 The significance of using RTOS on MSP430
It is understandable that it is meaningless to use RTOS on MSP430. Because the hardware resources of MSP430 are limited (for exampl...[Details]
Introduction
Power subsystems are becoming more and more integrated into the overall system. Power systems have moved from being separate "essential dangerous devices" to being monitorable...[Details]
With the advocacy and implementation of the government's Safe City Plan, the security market has increasingly higher requirements for the clarity of surveillance images. Imagine that after a case o...[Details]
1. Disadvantages of choosing too high a voltage level
Choosing too high a voltage level will result in too high an investment and a long payback period. As the voltage level increases, the...[Details]
a. Keep the battery clean, wipe off the spilled electrolyte, contaminated dirt and dust in time; keep the poles and terminal clamps clean and in good contact, and apply vaseline or butter to preven...[Details]
The overall operating performance of an electric car depends first on its battery system and motor drive system. The drive system of an electric car is generally composed of three main parts: a con...[Details]
(1) Open circuit voltage of the battery
(2) Internal resistance of the battery
(3) Battery operating voltage
(4) Charging voltage
Charging voltage refers to the voltage applied ...[Details]
This paper first proposed an elevator controller algorithm based on a finite state machine, and then designed a three-story elevator controller based on the algorithm. The correctness of the elevat...[Details]
3. Driving circuit design
The power driver uses a field effect tube, which is a field-controlled device with a capacitance effect between the gate and source, so it has high requirements for t...[Details]

At present, the DES algorithm is increasingly used in confidential communications in the financial and non-financial sectors. DES (Data Encryption Standard) is a data encryption algorithm that was suc...[Details]
Conventional crystalline silicon solar cells are made on high-quality silicon wafers with a thickness of 350-450μm, which are sawn from pulled or cast silicon ingots. Therefore, more silicon materi...[Details]
