I use FreeScale's i.MX31 (ARM11) to build an embedded system. I can use interrupts under WinCE, but I can't see the code for initializing interrupts in winCE! I built a BootLoader in ADS1.2, but I can...
Incompatible runtime models. Module APS specifies that '__code_model' must be 'banked', but module AF has the value 'near' This problem occurs when compiling with Zstack. What is the cause of this pro...
I wrote a small program for the MSP430FR series microcontroller and wrote some data into FRAM. During the first simulation, the read data was consistent with the written data. Then I exited and simula...
I am going to do a project recently, which is mainly to drive the display function of the segment LCD screen. The current tentative plan is to use STM8L as the main control chip and HT1621 as the LCD ...
In order to prevent traffic accidents, when the intelligent detection device of the car detects danger ahead, it must send a warning message to the driver. The voice alarm clearly reminds the drive...[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]
This article discusses how to use an ultra-low-power RF transceiver chip from Zarlink Semiconductor for pacemakers, neurostimulators, drug pumps, and other such implantable medical devices to achiev...[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]
As the whole equipment is constantly miniaturized and power-saving, low-power-consumption low-dropout linear regulators (LDO) are becoming the mainstream of the linear regulator market for switching p...[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]
Emulation Features
Emulation provides a set of standard operations for integration and debugging. Some of its main features are as follows:
BreakpointsA
common feature of emulatio...[Details]
WiMax technology needs to demonstrate its advantages in specific application scenarios in order to gain market recognition, which requires application testing to measure system performance para...[Details]
Portable devices with audio functions (such as portable media players and multimedia mobile phones) require long audio playback time, that is, long battery life. To extend the battery life of port...[Details]
There are many ways to attenuate signals. The most commonly used method is to divide the voltage using resistors. The common circuits are as follows:
Oscilloscope pre-stage attenuation c...[Details]
Today, various applications such as consumption, computers, industry and instruments urgently need compact and effective power solutions, while also meeting the requirements of efficiency, fast tra...[Details]
1. Introduction
Rolling bearings are the most widely used general mechanical components in various rotating machines. Whether their operating status is normal often directly affects the perfo...[Details]
Introduction
As a kind of biometric identification, fingerprint recognition has incomparable advantages in identity recognition over other means: human fingerprints are unique and stable; wit...[Details]
FSK (Frequeney-Shift Keying) uses carriers of different frequencies to transmit digital signals. FSK signals have the advantages of strong anti-interference ability and long transmission distance, and...[Details]
Focus shift problem
Visible light and infrared light have different wavelengths, so the imaging focus is not on the same plane, which results in a clear image under visible light condition...[Details]
