FRDM-K82F interface with RC663

sagar_prajapati — Thu, 05 Sep 2019 13:03:48 GMT

Hello all,

I have downloaded code from nxp site and made connection as per document. Also define PHDRIVER_FRDM_K82FRC663_BOARD in preprocessor. I am able to read chip id 0x1a but Card is not detected. Please help me to get out of this issue.

Thanks

Sagar

Code stops at phOsal_sleep() function.

Did you download the latest NFC reader library for FRDM-K82F?

and are you referring to https://www.nxp.com/docs/en/application-note/AN11908.pdf ?

Were CLEV6630B and FRDM-K82F used on your side?

Please kindly clarify.

Thanks for your patience!

Have a great day,
Kan

Hello @yen_chen

I have solved this issue.

Actually I do not remember exact solution for this but as I remember I have done 2 changes in the code that I suggest you to do.

1. Add minor delay in continous card detection polling loop. I have checked the example for MifareClassic. I am attaching sample code for your reference.

2. Increase heap Size if you are running this code with RTOS. IF you are running with Baremetal then no need to increase heap Size.

do
{
/* Field OFF */
status = phhalHw_FieldOff(pHal);
CHECK_STATUS(status);

status = phhalHw_Wait(pDiscLoop->pHalDataParams,PHHAL_HW_TIME_MICROSECONDS, 5100); //5100
CHECK_STATUS(status);

/* Configure Discovery loop for Poll Mode */
status = phacDiscLoop_SetConfig(pDiscLoop, PHAC_DISCLOOP_CONFIG_NEXT_POLL_STATE, PHAC_DISCLOOP_POLL_STATE_DETECTION);
CHECK_STATUS(status);

/* Run Discovery loop */
status = phacDiscLoop_Run(pDiscLoop, PHAC_DISCLOOP_ENTRY_POINT_POLL);
vTaskDelay(10);

}while((status & PH_ERR_MASK) != PHAC_DISCLOOP_DEVICE_ACTIVATED); /* Exit on Card detection */

Please do above changes and let me know whether this works or not. If you find any error please let me know I will bring the hardware and test again.

Waiting for your reply.

Hi @sagar_prajapati

Thank you your reply.

I try the option2 but it can't work in my project.

I use example BasicDiscoveryLoop, it don't have delay can set.

I think maybe my pin define cause some error.

My pin didn't be pulled up in the DAL/board setting.

Thank you your reply again .

Br,

Yen

Hello @yen_chen

Give me some time I will collect hardware and check and update you. I will also run basicdiscovery loop example.
