Hi,
I've been using the SDK shipped with a vendor product and a feature that I use is to acquire the SPIS semaphore as part of the SPIS handler. The version of the SDK that comes with the vendor product has this snippet in nrfx_spis.h:
/** @brief SPI slave driver event types. */
typedef enum
{
NRFX_SPIS_BUFFERS_SET_DONE, //!< Memory buffer set event. Memory buffers have been set successfully to the SPI slave device, and SPI transaction can be done.
NRFX_SPIS_XFER_DONE, //!< SPI transaction event. SPI transaction has been completed.
NRFX_SPIS_BUFFER_END, //!< SPI transaction event. SPI Rx Buffer has been filled.
NRFX_SPIS_SPIS_ACQUIRED, //!< SPI transaction event. SPI Semaphore has been acquired.
NRFX_SPIS_EVT_TYPE_MAX //!< Enumeration upper bound.
} nrfx_spis_evt_type_t;
Now the vendor has shipped an updated product with updated Nordic libraries and the same file now has this:
/** @brief SPI slave driver event types. */
typedef enum
{
NRFX_SPIS_BUFFERS_SET_DONE, //!< Memory buffer set event. Memory buffers have been set successfully to the SPI slave device, and SPI transaction can be done.
NRFX_SPIS_XFER_DONE, //!< SPI transaction event. SPI transaction has been completed.
NRFX_SPIS_EVT_TYPE_MAX //!< Enumeration upper bound.
} nrfx_spis_evt_type_t;
Notably, no NRFX_SPIS_SPIS_ACQUIRED enumeration.
What is the recommended way to acquire the SPIS semaphore?
Regards,
AC
