RFID Click PROBLEM

[Prsli]

Hello,

I bought RFID Click board but i cant find example for pic, there is only example for arm.

Could you please provide me with a working example?

Thank you

Hellp, i am trying to run the code from arm example for RFID. It builds without errors but it gets stuck at

while (!EchoResponse()) {
LATE = 0xFF;
IRQ_IN = 1;
delay_ms(1);
IRQ_IN = 0;
delay_ms(1);

}

EchorResponse function always returns 1 and it never gets out of above while loop

char EchoResponse() {

CS = 0;

SPI1_Write(0x00); // Send cmd to CR95HF

SPI1_Write(ECHO);
CS = 1;


while(1){

CS = 0;
SPI1_Write(0x03);
tmp = SPI1_Read(0);
CS = 1;

if((tmp & 0x08) >> 3){

CS = 0;
SPI1_Write(0x02);
tmp = SPI1_Read(0);
CS = 1;
if(tmp == ECHO){

return 1;
}
return 0;
}
}
}

I think spi always reads 0x00.


only thing that i changed is instead of
SPI1_Init_Advanced(_SPI_FPCLK_DIV64, _SPI_MASTER | _SPI_8_BIT | _SPI_CLK_IDLE_LOW | _SPI_FIRST_CLK_EDGE_TRANSITION | _SPI_MSB_FIRST | _SPI_SS_DISABLE | _SPI_SSM_ENABLE | _SPI_SSI_1, &_GPIO_MODULE_SPI3_PC10_11_12);


i putted spi1_init(); since advanced init parameters dont exist.

Rfid is connected on portc on Easy for pic board.(pic18f45k22)

Is anyone from support department reading these forums?

Hello,

I'm sorry for late reply, I myself have tried to test the RFid click(SPI) with EasyPIC v7.
Unfortunately I ran on similar problem as you reported.

I'll need to make future investigation to find out what is the cause of the problem.

In the mean whille I suggest that you try to interface the board via UART.

Best regards.

Thank you for your reply.

I have WIFI Click Plus on my portD connected via UART. Is i ok if i also use uart connection for RFID on portC or will they interfere?

I will tinker with it while I wait for your findings.

Cheers

Hello,

There should be no interferece between two different UART modules.

Best regards.

[Prsli]

Any news on my problem?

Also is there an example for RFID Click connected over UART?

Also can I use INT_O and INT_I pins instead of moving jumpers to position to use RX and TX pins?

Thank you

I apologize.
Thank you for working on my problem.

Hello,

Please try testing this project.
Just make sure that you short connect the RE1(SI0) with VCC pin like noted in comment header.

Best regards.
