CC2640: MRDY & SRDY pin configuration

Hello,

MRDY & SRDY are GPIOs, so any available DIO can be used. Refer to the npiHandshakePinsCfg struct:

static PIN_Config npiHandshakePinsCfg[] =
{
MRDY_PIN | PIN_GPIO_OUTPUT_DIS | PIN_INPUT_EN | PIN_PULLUP,
SRDY_PIN | PIN_GPIO_OUTPUT_EN | PIN_GPIO_HIGH | PIN_PUSHPULL | PIN_DRVSTR_MAX,
PIN_TERMINATE
};

The default IO settings are in npi_config.h, but they can be modified to any valid DIO.

Best wishes

Hello,

Thank you for your answer. Is it possible to see the npi_config.h portion with the default pin settings?

Thank you

Hello,

Yes, you can find npi_config.h in <SDK>\Components\npi\inc

Best wishes

Hello,

Thank you for your answer. I cannot find the reference to DIO# in the file

define MRDY_PIN Board_KEY_UP
define SRDY_PIN Board_KEY_DOWN

What do Board_KEY_UP and Board_KEY_DOWN refer to in terms of DIO?

Thank you.

Hi,

Board_KEY_UP / _DOWN are probably just defines for certain DIOs made in the board file. Can you check board.h or do a global search for Board_KEY_UP?

Cheers,
Fredrik
