CC2640R2F: problem with simultaneous operation of spi and bluetooth

Hello Yura,

Can you provide some more information?

Where are you running this init code?
Have you modified the board files or CC2640_LAUNCHXL files?

Regards,
AB

Hello, AB, thank you for your interest!

I am trying to init spi inside main function, before BIOS_start();.
Earlier I was trying to run code for SPI initialization just before data tranfering, but it did not worked

int main()
{

/* Register Application callback to trap asserts raised in the Stack */
RegisterAssertCback(AssertHandler);

PIN_init(BoardGpioInitTable);

PIN_init(SMPinTable);
PIN_init(ledPinTable);
PIN_init(ButtonTable);
PIN_init(BuzTable);
ADC_init();


SPI_Handle spi;
SPI_Params spiParams;
SPI_Transaction spiTransaction;
uint8_t ( * transmitBuffer)[14];
uint8_t receiveBuffer[14];
bool transferOK;
spiParams.dataSize = 8; // 8-bit data size
SPI_init();
SPI_Params_init(&spiParams); // Initialize SPI parameters
spi = SPI_open(Board_SPI0, &spiParams);


my code;

}


I configured BoardGpioInitTable from ProjectZero in CC2640R2_LAUNCHXL.c. I commented not used pins and left SPI pins

const PIN_Config BoardGpioInitTable[] = {

// CC2640R2_LAUNCHXL_PIN_RLED | PIN_GPIO_OUTPUT_EN | PIN_GPIO_LOW | PIN_PUSHPULL | PIN_DRVSTR_MAX, /* LED initially off */
// CC2640R2_LAUNCHXL_PIN_GLED | PIN_GPIO_OUTPUT_EN | PIN_GPIO_LOW | PIN_PUSHPULL | PIN_DRVSTR_MAX, /* LED initially off */
// CC2640R2_LAUNCHXL_PIN_BTN1 | PIN_INPUT_EN | PIN_PULLUP | PIN_IRQ_BOTHEDGES | PIN_HYSTERESIS, /* Button is active low */
// CC2640R2_LAUNCHXL_PIN_BTN2 | PIN_INPUT_EN | PIN_PULLUP | PIN_IRQ_BOTHEDGES | PIN_HYSTERESIS, /* Button is active low */
// CC2640R2_LAUNCHXL_SPI_FLASH_CS | PIN_GPIO_OUTPUT_EN | PIN_GPIO_HIGH | PIN_PUSHPULL | PIN_DRVSTR_MIN, /* External flash chip select */
// CC2640R2_LAUNCHXL_UART_RX | PIN_INPUT_EN | PIN_PULLDOWN, /* UART RX via debugger back channel */
// CC2640R2_LAUNCHXL_UART_TX | PIN_GPIO_OUTPUT_EN | PIN_GPIO_HIGH | PIN_PUSHPULL, /* UART TX via debugger back channel */
CC2640R2_LAUNCHXL_SPI0_MOSI | PIN_INPUT_EN | PIN_PULLDOWN, /* SPI master out - slave in */
CC2640R2_LAUNCHXL_SPI0_MISO | PIN_INPUT_EN | PIN_PULLDOWN, /* SPI master in - slave out */
CC2640R2_LAUNCHXL_SPI0_CLK | PIN_INPUT_EN | PIN_PULLDOWN, /* SPI clock */

PIN_TERMINATE
};

Hello, AB!
Opening SPI in actual task and calling SPI transferring functions does not influence on the device behavior. This is the code under consideration

int main()
{

My code
/* Initialize ICall module */
ICall_init();

/* Start tasks of external images - Priority 5 */
ICall_createRemoteTasks();

/* Kick off profile - Priority 3 */
GAPRole_createTask();

// controller task. SPI is called here
Controller_createTask();

TimeCtrl_createTask();

ProjectZero_createTask();

/* enable interrupts and start SYS/BIOS */
BIOS_start();

return 0;
}

Part of controller task code following

void Controller_createTask(void)
{
Task_Params CtrltaskParams;

// Configure task
Task_Params_init(&CtrltaskParams);
CtrltaskParams.stack = CtrlprzTaskStack;
CtrltaskParams.stackSize = TASK_STACK_SIZE;
CtrltaskParams.priority = TASK_PRIORITY;
Task_construct(&CtrlprzTask, Controller_taskFxn, &CtrltaskParams, NULL);
// System_printf("ctrl task started.\n");
}

void Controller_taskFxn (UArg a0, UArg a1)
{
Code, preliminary setup of the device
while (1)
{
My code
SPI_write();
My code
} // end of while (1)
} // end of Controller_taskFxn
void SPI_write (void)
{
SPI_Handle spi;
SPI_Params spiParams;
SPI_Transaction spiTransaction;
uint8_t ( * transmitBuffer)[14];
uint8_t receiveBuffer[14];
bool transferOK;
spiParams.dataSize = 8; // 8-bit data size
SPI_Params_init(&spiParams); // Initialize SPI parameters
spi = SPI_open(Board_SPI0, &spiParams); // if (spi == NULL)
// {
// while (1); // SPI_open() failed
// }

PIN_setOutputValue(ledPinHandle, CS, 0); //CS = 0

transmitBuffer = &data_to_send;
spiTransaction.count = 1;
spiTransaction.txBuf = transmitBuffer;
spiTransaction.rxBuf = receiveBuffer;

transferOK = SPI_transfer(spi, &spiTransaction);
if (!transferOK)
{
// Error in SPI or transfer already in progress.
}

PIN_setOutputValue(ledPinHandle, CS, 1); //CS = 1


} // end of SPI_write()


I will try to create one more task for SPI and answer.

Hello Yura,

Have you been able to get this working?
did you create a separate task since last post?

AB

Hello!

Your advice did not help.

I think the reason was too big size of the hex file.

But I can not chek this now, becouse we do not need SPI on our project any more.

Thank you a lot for your help!
