Thinhnguyenky 0 Posted July 31, 2016 Share Posted July 31, 2016 Thank for your share !! but i have a problem, t can't understand some code senten : "Mfrc522 Mfrc522(chipSelectPin,NRSTDP); " ," Mfrc522.Init();" "Mfrc522.Request(PICC_REQIDL, str); " ..... Quote Link to post Share on other sites
Fmilburn 446 Posted July 31, 2016 Share Posted July 31, 2016 Hi @@Thinhnguyenky and welcome to 43oh... The library for the card reader has a number of functions that allow the user to access and use the device. Mfrc522 Mfrc522(chipSelectPin,NRSTDP); - creates a new instance named Mfrc522 that can be used to access the library Mfrc522.Init();" - initializes the device using the instance specified above Mfrc522.Request(PICC_REQIDL, str); - requests information from the card reader The examples give simplified code that demonstrates how they work. If you need a beginner's guide on how a library works see this: http://energia.nu/guide/tutorial_library/ If you would like to see the specific code and documentation associated with these functions then look in the .cpp and .h files that come with the library.

mertkarakurtjk 0 Posted August 13, 2016 Share Posted August 13, 2016 Hi everyone,Is it possible this source code and libraries are adapted for MSP432P401R ? If it is,how can I do please explain for me.. I have MSP430,432 and RC552.This code is running on MSP430 but I want to run on MSP432. Thanks for supports. Quote Link to post Share on other sites
Fmilburn 446 Posted August 13, 2016 Share Posted August 13, 2016 Hi @@mertkarakurtjk and welcome to 43oh. For some reason the MF RC 522 library does not work for me on the MSP432 either but I haven't had time to look into it. Quote Link to post Share on other sites
ticoder 0 Posted February 6, 2017 Share Posted February 6, 2017 Maybe it will help someone. You can use arduino's library https://github.com/miguelbalboa/rfid with Energia. All that you need is comment out all SPI.beginTransaction and SPI.endTransaction lines in MFRC522.cpp, and also define SS constant (SDA/chip select pin number, #define SS 8 in my case) in the same file. After this library itself and library exambles are working at least on Tiva C launchpad. Quote Link to post Share on other sites

Tried knocking together some code to allow hard coding of tag IDs which works OK. Might need to change the for loop though as anything in else just gets repeated, a switch might do the trick but it's late. For anyone interested, here's my code, would appreciate any improvements that could be made, including an scenario where the tag's not recognized as valid. /* Example file for communicating with the NFRC522.
