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...
Until now, designers have faced a trade-off in ADC selection. Pipeline converters offer high resolution and wide dynamic range, but their power consumption is quite high. The alternative, discrete ...[Details]
No other sector is feeling the pressure for change more acutely than the healthcare industry. Healthcare organizations and services are desperate to reduce costs, but the challenge is to do so without...[Details]
As a single-host multi-slave bus system, the number of slave devices that can be connected to a 1-Wire bus is almost unlimited. In order to avoid logical conflicts, the 1-Wire bus interfaces of all...[Details]
In the field of software development, the most critical but also the most unpredictable phase is the debugging phase. There are many factors that play a role in the process of software debugging, a...[Details]
Today, as network technology becomes more and more popular, industrial field instruments, data acquisition and control equipment are becoming more and more networked, and the combination of industr...[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]
Preface
Phase-modulated pulse signals can achieve a large compression ratio. As a commonly used pulse compression signal, they are widely used in modern radar and communication systems. Wi...[Details]
Complex circuits and 3D EM simulation tools have reached a point where complex system-level behavior can be simulated before fabrication. Performing EM simulations simultaneously with circuit simul...[Details]
Power Integrations (PI) has introduced three charger/adapter reference designs using its new LinkSwitch-II series of AC-DC switching power conversion ICs. The new LinkSwitch-II devices use high-pre...[Details]
