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...
