Hello everyone: The module model I use is USI's WM-G-MR-09, and the chip used in the module is Marvell 8686. When I transplanted it to freescale mx31, I couldn't read the ID of the wifi module, but wh...
I recently encountered a very confusing problem: 1. Checking the clock tree in the STM32F103XXX reference manual, the maximum SYSCLK is 8/2*9=36MHz;2. Checking STM32_Library_Manual, 15.2.6 function vo...
Designers of Internet of Things (IoT) products are currently gravitating toward wireless connectivity based on Wi-Fi because it is widely deployed and well understood. However, any type of RF function...
Since there is no floppy drive on a Pentium4 machine, I can only use a USB flash drive to create a bootrom disk to start it. However, the problem encountered during the boot process is: after booting,...
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]
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]
Human body information monitoring is an emerging field. People envision developing wireless electroencephalogram (EEG) monitoring equipment to diagnose epilepsy patients. Wearable wireless EEG can ...[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]
Preface
Sleep apnea is a very common sleep breathing disease. According to research, about 24% of adult men and 9% of adult women, or more than 2 million people, suffer from this disease ...[Details]
Controller Area Network (CAN) is a type of fieldbus. It is a serial communication network that effectively supports distributed control or real-time control and is recognized as one of the most pro...[Details]
Safety is the top priority in the production process, especially for dangerous operations. When the high-voltage line is shut down for maintenance, it is necessary to follow the regulations of powe...[Details]
JTAG Technology Introduction
One disadvantage of shrinking technology is that the complexity of testing small devices increases dramatically. When the board area is large, the board is tested...[Details]
Basic principles of simulation
Simulation is a technology used in the field of embedded system development. It can bring system developers the controllability and visibility needed to integra...[Details]
This summary will introduce the transmitter characteristic test of TD terminal products - uplink power control. According to the 3GPP TS34.122 standard, UE uplink power control is divided into uplink ...[Details]
Abstract: Based on the research of the communication process between the reader and the RFID tag, combined with the EPC C1G2 protocol and ISO/IEC18000.6 protocol, a digital circuit of RFID tag appl...[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]
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]
In order to ensure the reliability of the driving assistance system and the basic functions of the car, and also to leave suitable connection interfaces for the car's future new entertainment and ...[Details]
introduction
In engineering practice, ultrasonic waves are often used to measure distances because of their strong directivity, slow energy consumption, and long propagation distance in th...[Details]
