This is my first time to use GPRS module and I don't know what issues should be considered when choosing a module. Now I know that I mainly need to use this module for SMS service and need a module wi...
How to change the serial port 0 to the serial port 1 of CC2541 BLE protocol stack? The default is serial port 0. I use the BLE-1.4.1 protocol stack. I changed the serial port to serial port 1, P1_4, P...
[align=left]I am currently working on a security access control product. The RF reader/writer chip I use is NXP's MFRC523, a 13.56MHz contactless RF reader/writer chip. Do you have any other similar R...
I want to implement XML data transmission on SmartARM2200 development board. Of course, it requires the ability to parse XML data. I have found a lot of information, but I really don't know how to sta...
The circuit in the picture is the circuit I tested! Applying a momentary force at both ends of the piezoelectric ceramic (the thing that produces sparks in the lighter) will generate voltage at both e...
Project Overview
The micro urine analyzer we designed can detect ten parameters of urine, including white blood cells, nitrite, urobilinogen, protein, pH value, occult blood, specific g...[Details]
Magnetic resonance imaging (MRI) systems can take high-resolution cross-sectional perspective images of the human body, providing very useful information for medical diagnosis. The radio frequency pro...[Details]
The circuit shown in the figure is a three-digit tachometer used to measure low frequency signals with a repetitive time interval of 0.235 to 15 seconds. The tachometer has a speed range of 4 to 255 r...[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]
Designers of hearing aids have stringent requirements. Hearing aids must be small enough to fit in or behind the ear, operate on ultra-low power, and be free of noise or distortion. To meet these requ...[Details]
Keeping the heart environment compact and warm is beneficial in most cases, but it’s another story for electronic heart scanners. When GE Healthcare was designing a scanner that was said to be the fas...[Details]
With the rapid development of digital technology, various digital display screens have emerged, including LED, LCD, DLP, etc. There are various control systems for various digital large screens, in...[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]
As the price of readers and tags decreases and the global market expands, the application of radio frequency identification (RFID) is increasing day by day. Tags can be powered by readers (passive ...[Details]
Signal sources have developed to a very wide range today. We can classify them according to the frequency range: ultra-low frequency (0.1m～1kHz), audio (20Hz～20kHz), video (20kHz～10MHz), radio fre...[Details]
DC regulated power supply is a commonly used electronic device, which can ensure stable output voltage when the grid voltage fluctuates or the load changes. A low ripple, high-precision regulated p...[Details]
Many MEMS devices, such as accelerometers and mechanical resonance devices, require a vacuum environment to realize their designed functions. However, verifying whether the package cavity has reach...[Details]
introduction
The data detected by various measuring instruments often need to be transferred to the PC for data processing and archiving, so as to make full use of the rich hardware and softwa...[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]
