I am using a PSoC5 with Cypress Creater to read an RFID tag with a MFRC522 chip. It is in C. This is the code I have below. I honestly don't know if the registrar and values I send to it are correct. Any help would be amazing. I only really need teh UID that is unique to each tag.

#include "project.h"

void lock()

{ uint8 motorVal = 9;

LCD_Position(1,0);

for(int x = 0; x <= 2; x++)

{

MotorPort_Write(motorVal);

motorVal = 5;

CyDelay(500);

MotorPort_Write(motorVal);

motorVal = 6;

CyDelay(500);

MotorPort_Write(motorVal);

motorVal = 10;

CyDelay(500);

MotorPort_Write(motorVal);

motorVal = 9;

CyDelay(500);

}

}

void unlock()

{

uint8 motorVal = 6;

LCD_Position(1,0);

for(int x = 0; x <= 2; x++)

{

MotorPort_Write(motorVal);

motorVal = 5;

CyDelay(500);

MotorPort_Write(motorVal);

motorVal = 9;

CyDelay(500);

MotorPort_Write(motorVal);

motorVal = 10;

CyDelay(500);

MotorPort_Write(motorVal);

motorVal = 6;

CyDelay(500);

}

}
