I encountered two problems in learning ucos that I couldn't figure out: 1. How to handle peripheral interrupts in ucos, such as serial ports 2. How to use global variables in ucos...
Power Stage DesignerTM is a JAVA-based tool (requires JAVA 8 or OpenJDK 8) that helps engineers speed up the power supply design process by calculating voltages and currents for 20 topologies based on...
rt, let A be the master station, B and C be slave stations, and S be the mobile sound source. By measuring the time difference ΔtAB from S to station A and station B, and the time difference ΔtAC from...
SPI and DMA initialization are automatically generated by STM32CUBEMX. The external memory is LY68L6400. I use HAL_SPI_Transmit(hspi2,(uint8_t * )TX_data, 1020, 0xfffffff);
The function writes data to...
This article describes the best ways to improve performance, encoding success rates, and increase uptime with RFID smart labels. It can help you get more value from your smart label printing system by...
Designers use PSpice primarily to simulate analog circuits. However, it can also be used to simulate digital filters. The main components in a digital filter are delay elements, adders, and multipl...[Details]
introduction
Oxygen is an important substance for human metabolism. Brain tissue has a high metabolic rate and consumes about 20% of the total oxygen in the body. In the clinical rescue and ...[Details]
The latest C language tools allow you to quickly complete the design of algorithm-intensive applications even if you are not proficient in hardware development.
Hardware designers have b...[Details]
In some applications, such as data loggers, it is desirable to have multiplexed analog outputs. When only a single output is active at a time, a voltage-output DAC">digital-to-analog converter (DAC) a...[Details]
Magnetic resonance imaging (MRI) systems for medical and scientific applications require a high-performance, high-power inductor capable of establishing a uniform, strong magnetic field. Transverse el...[Details]
Pulse oximeters, non-invasive instruments used to monitor a patient's blood oxygen saturation, are benefiting from moving away from expensive discrete component solutions toward more integrated design...[Details]
At present, the global medical electronics industry is gradually showing attractive development prospects, and the speed of product replacement is constantly increasing. At the same time, due to the p...[Details]
The particularity of portable medical devices determines that they should be user-friendly, must work in a sterile environment, and occupy little space and consume low energy.
At the same time, por...[Details]
Today's mobile phone production testing faces an increasingly complex environment, with challenges of multiple frequency bands and multiple standards, pressure on production test speed, and pressur...[Details]
In view of the problems in the actual FPGA development process, such as difficulty in locating faults, long compilation time after repeated code modification, and inability to confirm fault solutio...[Details]
To help improve DC/DC conversion efficiency at lighter loads and higher frequencies, Schottky diodes can be integrated into MOSFET chips to form a single package to reduce power dissipation in the ...[Details]
MOSFETs are widely used as power switching elements in regulators and motor controllers. They are available as discrete devices or integrated into ICs in various H-bridge configurations.
A hig...[Details]
Some application designs have higher requirements on the speed at which the system's switching power supply can provide voltage output. Figure

1. What is fading?
In terms of scope, fading can be roughly divided into three types: large area fading, small area fading and indoor fading. As shown in Figure 1, large area fading refers t...[Details]
Lifting wavelet transform not only has the advantages of traditional wavelet multi-resolution, but also simplifies the operation and is easy to implement in hardware. Therefore, it is widely used in d...[Details]
