KL25Z: pinmap not found for peripheral

Hello, I'm trying to get my RF24 board to work with my KL25Z, and I am using the code below, but it appears to not run at all. When I look at the serial output (screen Unix) all I get is "pinmap not found for peripheral". Any ideas?


 #include "mbed.h"
#include "nRF24L01P.h"

Serial pc(PTE22, PTE23); // tx, rx

nRF24L01P my_nrf24l01p(PTB3, PTB2, PTB1, PTC1, PTC2, PTB0);    // mosi, miso, sck, csn, ce, irq

//DigitalOut myled1(LED1);
//DigitalOut myled2(LED2);

int main() {

// The nRF24L01+ supports transfers from 1 to 32 bytes, but Sparkfun's
//  "Nordic Serial Interface Board" (http://www.sparkfun.com/products/9019)
//  only handles 4 byte transfers in the ATMega code.
#define TRANSFER_SIZE   4

    char txData[TRANSFER_SIZE], rxData[TRANSFER_SIZE];
    int txDataCnt = 0;
    int rxDataCnt = 0;


    // Display the (default) setup of the nRF24L01+ chip
    pc.printf( "nRF24L01+ Frequency    : %d MHz\r\n",  my_nrf24l01p.getRfFrequency() );
    pc.printf( "nRF24L01+ Output power : %d dBm\r\n",  my_nrf24l01p.getRfOutputPower() );
      pc.printf( "nRF24L01+ Data Rate    : %d kbps\r\n", my_nrf24l01p.getAirDataRate() );
   pc.printf( "nRF24L01+ TX Address   : 0x%010llX\r\n", my_nrf24l01p.getTxAddress() );
    pc.printf( "nRF24L01+ RX Address   : 0x%010llX\r\n", my_nrf24l01p.getRxAddress() );

    pc.printf( "Type keys to test transfers:\r\n  (transfers are grouped into %d characters)\r\n", TRANSFER_SIZE );

    my_nrf24l01p.setTransferSize( TRANSFER_SIZE );


    while (1) {

        // If we've received anything over the host serial link...
        if ( pc.readable() ) {

            // ...add it to the transmit buffer
            txData[txDataCnt++] = pc.getc();

            // If the transmit buffer is full
            if ( txDataCnt >= sizeof( txData ) ) {

                // Send the transmitbuffer via the nRF24L01+
                my_nrf24l01p.write( NRF24L01P_PIPE_P0, txData, txDataCnt );

                txDataCnt = 0;

            // Toggle LED1 (to help debug Host -> nRF24L01+ communication)
         //   myled1 = !myled1;

        // If we've received anything in the nRF24L01+...
        if ( my_nrf24l01p.readable() ) {

            // ...read the data into the receive buffer
            rxDataCnt = my_nrf24l01p.read( NRF24L01P_PIPE_P0, rxData, sizeof( rxData ) );

            // Display the receive buffer contents via the host serial link
            for ( int i = 0; rxDataCnt > 0; rxDataCnt--, i++ ) {

                pc.putc( rxData[i] );

            // Toggle LED2 (to help debug nRF24L01+ -> Host communication)
        //    myled2 = !myled2;

This normally means you are using the wrong pins, or even the wrong board for the compiler. Check you are compiling for the correct board.

According to MBED, I am using the right board. As for the pins, I am using the card that came with the KL25z

I think that PTB0 can not be used for interrupt.
For interrupt, use PTAx or PTDx.
For more details please refer to RM

Although it may not be necessary usually I use
PTD3 for miso
PTD2 for mosi
PTD1 for sclk
and use PTD0, PTD5, PTA13 for other control pins.


Thanks moto, this got me working, now I need to get it sending data, as the Arduino (client to the RF24) isn't receiving any data.
