* Sample arduino sketch using contiki features.
|
|
* We turn the LED off
|
|
* Unfortunately sleeping for long times in loop() isn't currently
|
|
* possible, something turns off the CPU (including PWM outputs) if a
|
|
* Proto-Thread is taking too long. We need to find out how to sleep in
|
|
* a Contiki-compatible way.
|
|
* Note that for a normal arduino sketch you won't have to include any
|
|
* of the contiki-specific files here, the sketch should just work.

* Example sketch/program showing how to read new NUID from a PICC to serial.
|
|
* ------------------------------------------------------------------------------------------------------------$
|
|
* This is a MFRC522 library example; for further details and other examples see: https://github.com/miguelbalb$
|
|
*
|
|
* Example sketch/program showing how to the read data from a PICC (that is: a RFID Tag or Card) using a MFRC52$
|
|
* Reader on the Arduino SPI interface.
|
|
*
|
|
* When the Arduino and the MFRC522 module are connected (see the pin layout below), load this sketch into Ardu$
|
|
* then verify/compile and upload it. To see the output: use Tools, Serial Monitor of the IDE (hit Ctrl+Shft+M)$
|
|
* you present a PICC (that is: a RFID Tag or Card) at reading distance of the MFRC522 Reader/PCD, the serial o$
|
|
* will show the type, and the NUID if a new card has been detected. Note: you may see "Timeout in communicatio$
|
|
* when removing the PICC from reading distance too early.
