I'm working on CAN communication of stm32 recently. I found that the communication is normal in self-test mode, but the peripheral node can receive data. After changing to normal mode, the peripheral ...
The current signal output by instruments and sensors is mostly 4-20mA. Why is it 4-20mA? Because 4-20mA sensors are mostly two-wire systems, that is, the signal line and the power line share two wires...
In the introduction to the principle of DCDC DC chopper, why is it said that the inductor current changes linearly with the external voltage, and then the inductor voltage is said to be stable rather ...
In embedded real-time kernels, an event is a mechanism that indicates that a predefined system event has occurred. The event mechanism is used for synchronization between tasks and between tasks and I...

1. Fault phenomenon and cause analysis
1. During the operation of the equipment, the expansion sleeve is subjected to a large torque, and the mating surfaces of the shaft and the sleeve move...[Details]
During daily operation of an R-type power transformer, the voltage used varies as the equipment being used adjusts. This raises the question: can the transformer change voltage at this point? The a...[Details]
Over the past decade, the narrative surrounding fuel vehicles has been one of decline and replacement. Under the onslaught of new energy vehicles, traditional automakers have been forced to acceler...[Details]
In the field of communications power supplies, AC/DC rectifier power supplies are called primary power supplies or basic power supplies, while DC/DC converters are called secondary power supplies. ...[Details]
With the advancement of science and technology and the promotion of green, energy-saving, and circular development, the demand for precise control and accurate measurement is increasing. In the pow...[Details]
