CCS/CC2640: Adding NPI_SPI into simple_peripheral project , but compiling failed

Part Number: CC2640

Tool/software: Code Composer Studio

Adding NPI_SPI into simple_peripheral project , but compiling failed .

My detail steps is shown as followed:

1.On CC2640 LAUNCHPAD , add NPI_SPI into simple_peripheral project according to 《Cc2640_Adding_a_UART_or_SPI_driver_to_a_Sample_Project》.

2. download the “tl.h” and “tl.c ” file . The path is shown in attachments 6(6) and 6(7).

3. add NPI_SPI into simple_peripheral project according to 《Cc2640_Adding_a_UART_or_SPI_driver_to_a_Sample_Project》.

4.compile the simple_peripheral project , but it failed , as shown in picture 1 .

5. the reason why compiling failed is that "sem" is not defined in this project .The code is shown as followed:

#if defined (NPI_USE_UART) || defined (NPI_USE_SPI)
  //initialize and pass information to TL
  TLinit(&sem, &SimpleBLEPeripheral_TLCBs, TRANSPORT_TX_DONE_EVENT,
         TRANSPORT_RX_EVENT, MRDY_EVENT);
#endif //TL

Hi Heng,

The guide you are following is intended for the CC2640, not the CC2640R2F.

I would suggest you take a look at the Serial Port Profile (SPP) examples on github: github.com/.../simplelink_sdk-1.40

Thanks for your reply!

After downloading and compiling the spp_ble_client project from Github , it shows build success . However , the spp_ble_client project is based on UART , instead fo SPI , as shown in picture 1 .Where can spp_ble_client project based on SPI be downloaded ?

The SDITLUART_initializeTransport() function in sdi_tl_uart.c shows the uart init parameters , shown as followed:

void SDITLUART_initializeTransport(Char *tRxBuf, Char *tTxBuf, sdiCB_t sdiCBack)
{
    // Set UART transport callbacks
    TransportRxBuf = tRxBuf;
    TransportTxBuf = tTxBuf;
    sdiTransmitCB = sdiCBack;

    // Initialize the UART driver
    Board_initUART();

    // Configure UART parameters.
    UART_Params_init(&paramsUART);
    paramsUART.baudRate = SDI_UART_BR;
    paramsUART.readDataMode = UART_DATA_BINARY;
    paramsUART.writeDataMode = UART_DATA_BINARY;
    paramsUART.dataLength = UART_LEN_8;
    paramsUART.stopBits = UART_STOP_ONE;
    paramsUART.readMode = UART_MODE_CALLBACK;
    paramsUART.writeMode = UART_MODE_CALLBACK;
    paramsUART.readEcho = UART_ECHO_OFF;

    paramsUART.readCallback = SDITLUART_readCallBack;
    paramsUART.writeCallback = SDITLUART_writeCallBack;

    //paramsUART.readReturnMode = UART_RETURN_FULL;

    // Open / power on the UART.
    uartHandle = UART_open(Board_UART0, &paramsUART);
    if(uartHandle != NULL)
    {
      //DEBUG("ERROR in UART_open");
    }
    //Enable Partial Reads on all subsequent UART_read()
    UART_control(uartHandle, UARTCC26XX_CMD_RETURN_PARTIAL_ENABLE,  NULL);


#if (SDI_FLOW_CTRL == 0)
    // This call will start repeated Uart Reads when Power Savings is disabled
    SDITLUART_readTransport();
#endif // SDI_FLOW_CTRL = 0

    return;
}

Where can  spp_ble_client project based on SPI be downloaded ?

Hi,

NPI/SDI still contains SPI support. You would have to tweak the application a bit to enable it to use the underlying SPI transport. For example, you would have to define NPI_USE_SPI in preprocessor settings.

I have already add the predefined symbols "NPI_USE_SPI" according to the second step of 《Cc2640 Adding a UART or SPI driver to a Sample Project》 , as shown in picture 1 .

Can you find out other possible reasons why the compiling failed ?

In the SDI folder of SPP project , only "sdi_tl_uart.c " can be found . "sdi_tl_spi.c" can never be found in the SDK, as shown in picture 1.

Where can the "sdi_tl_spi.c" of SPP be downloaded ?

Hi,

You have to add the files to the project from here:
C:\ti\simplelink_cc2640r2_sdk_1_40_00_45\source\ti\blestack\npi\src

I am having the same issues with my CC2640 (non R2) project. I have found npi_tl_spi.h and npi_tl_spi.c, but after searching my entire hard drive I cannot fin the missing file that is throwing the error shown in the image. Where can spi_tl_spi.h be found?

Hi,

You should replace all instance of sdi_tl_spi with npi_tl_spi (for ex. in sdi_tl.c) since you are using npi_tl_spi.h which should still work.

I understand that npi_tl_spi adds the ability to use packets that are similar to bootloader packets. Will replacing all instance of sdi_tl_spi with npi_tl_spi force me to use packets to send/receive bytes?

Hi,

If you do a diff between the NPI and SDI, you should see that the only file changed was npi_task/sdi_task. The other files were just cosmetic name changes.

You should be able to keep sdi_task and tweak it to use the original npi files that comes with the SDK.

Best wishes

Zahid Haq,

I would love to do a diff. Where can spi_tl_spi.h be found?

0 Zahid Haq over 7 years ago in reply to Dennis Page

TI__Mastermind 25035 points

For the latest CC2640 SDK, you should find the npi files in this directory:
C:\ti\simplelink\ble_sdk_2_02_02_25\src\components\npi\src
