We used MSP430F247 to build a project. During the production process, we found that after repeatedly plugging and unplugging the power supply of some machines, the system did not respond. We used the ...
Where is FIFO asynchronous used? It is impossible to use asynchronous with SPI and UART, because SPI has a synchronous clock and UART has a fixed baud rate. Is that right?...
As shown in the figure is a low voltage detection circuit. When the voltage is not lower than 4V, BC547 (the leftmost transistor) is turned on, causing the following two transistors to be cut off and ...
Hello everyone! We found that the serial port data is disordered when using MC9S08QE32, but the program is normal when using MC9S08QE128. What is the reason? Here is our test code: unsigned char *stri...
I want to make a DC motor PWM speed control board. In order to protect the power tube, I have to make an overcurrent protection. I have to connect a sampling resistor to the ground on the power tube. ...
Calibrators are widely used in university experiments. Among them, there are two experiments in nuclear physics experiments in modern physics experiments (GM counter and β absorption) that require ...[Details]
SinoWise's SH66xx series 4-bit microcontrollers have the characteristics of fast speed, low power consumption, simple structure, easy to use, and high cost performance. They are widely used in remo...[Details]
Although improper medical device product design is not always associated with medical device-related errors. Studies of users have shown that lack of adequate training accounts for 70% to 90% of suc...[Details]
For more than 10 years, analog-to-digital converters (ADCs) have been widely used in industrial process control, medical instruments, communication systems, radar and other products as a booster of in...[Details]
Microelectromechanical systems (MEMS) are gradually entering the consumer, industrial, medical, automotive and computer application markets. Moreover, we cannot ignore their steady progress in the ins...[Details]
Blood pressure is one of the important physiological parameters of the human body. Accurate measurement of it is conducive to early detection and identification of hypertension types, and to the pro...[Details]
The hardware circuit principle is shown in Figure 1. In the specific design, each part should consider the anti-interference problem to minimize the impact of interference on the performance of the...[Details]
The small size and low cost of home appliance control boards mean that high-cost materials will not be used in the circuit to solve the electromagnetic interference problem. The interference of hom...[Details]
Overview
Currently, many portable consumer electronic products, such as mobile phones, PDAs, MP3 players, and notebooks, are equipped with display screens. Although the type and size of the di...[Details]
Multiple Input and Multiple Output (MIMO) technology is arguably the next most important development in wireless communications since the advent of digital communications. Many new wireless commun...[Details]
1 Introduction
Generally, when transmitting information over short distances through electrical signals, baseband signals can be directly transmitted. However, over long distances, baseban...[Details]
A correct circuit design cannot be manufactured 100% correctly when it is taken to the factory for manufacturing. It will always be affected by various uncertainties, such as deviations in manufact...[Details]
With the improvement of people's requirements for vehicle riding comfort and the development of passenger car suspension technology in my country, air suspension is increasingly used in passenger ...[Details]
This paper introduces the technology and application of optical transceiver modules and digital non-volatile variable resistors in optical communication networks, and focuses on the design and appl...[Details]
The full name of RFID is Radio Frequency Identification, which uses radio frequency to realize data transmission between programmable controller (PLC) or microcomputer (PC) and identification, ther...[Details]
