Basically my code is to declare a raw_data[2238] arrary and pass it to
receive_response_14443a_readall function.
In this function, I will read all the incoming response from the RFID tag.
In my other functions, I also used the similar approach but with a smaller
raw_data value of raw_data[500] to get the response value and it works.
Below are the codes:
void Read_all_14443a_type1(cyg_uint32 uid0, cyg_uint32 uid1, cyg_uint32 uid2,
cyg_uint32 uid3) {
cyg_uint32 request[9];
cyg_uint32 binary[71];
cyg_uint32 symbol[89];
cyg_uint32 processed_data[124];
cyg_uint32 CRC;
int i,parity_check,byteValue;
int responseFlag=0;
int raw_data [2238];
.
.
.
responseFlag=receive_response_14443a_readall(raw_data,1,0,500);
int receive_response_14443a_readall(int *raw_data, int loopvalue, int delay,
int listen) {
cyg_uint32 readDOUT, readDSYNC;
readDOUT=0x00;
int timeout = 0;
int i,j;
int k=0;
int responseFlag=0;
int count=0;
delay_us(15);
.
.
.
do{
HAL_READ_UINT32(AT91_PIOC+AT91_PIO_PDSR,readDSYNC);
readDSYNC= readDSYNC & 0x8;
}
while(readDSYNC ==0x8);
HAL_READ_UINT32(AT91_PIOC+AT91_PIO_PDSR,readDOUT);
readDOUT= readDOUT & 0x40;
if(readDOUT == 0){
k++;
*raw_data=0;
}
else
*raw_data=1;
delay_us(3);
count++;
raw_data++;
Thanks for helping...
