Functions

void evk_radio_peripherals_init(void)

Initialize all peripherals related to the SR10x0 radio.

bool evk_radio_read_irq_pin(void)

Read the status of the on-board controller IRQ pin.

Return values:

  • True – Pin is high.

  • False – Pin is low.

void evk_radio_enable_irq_it(void)

Enable the on-board controller IRQ external interrupt.

void evk_radio_disable_irq_it(void)

Disable the on-board controller IRQ external interrupt.

void evk_radio_enable_dma_irq_it(void)

Enable the DMA SPI interrupt of the radio.

void evk_radio_disable_dma_irq_it(void)

Disable the DMA SPI interrupt of the radio.

void evk_radio_set_shutdown_pin(void)

Set the on-board controller shutdown pin.

void evk_radio_reset_shutdown_pin(void)

Reset the on-board controller shutdown pin.

void evk_radio_set_reset_pin(void)

Set the on-board controller reset pin.

void evk_radio_reset_reset_pin(void)

Reset the on-board controller reset pin.

void evk_radio_spi_set_cs(void)

Set the on-board controller chip-select pin.

void evk_radio_spi_reset_cs(void)

Reset the on-board controller chip-select pin.

void evk_radio_set_debug_en(void)

Set the on-board controller debug enable pin.

void evk_radio_reset_debug_en(void)

Reset the on-board controller debug enable pin.

void evk_radio_spi_write_blocking(uint8_t *data, uint8_t size)

Write data on the SPI communication bus.

Parameters:

  • data – [in] Data buffer to write.

  • size – [in] Size of the data to write.

void evk_radio_spi_read_blocking(uint8_t *data, uint8_t size)

Read data on the SPI communication bus.

Parameters:

  • data – [out] Data received.

  • size – [in] Size of the data to read.

void evk_radio_spi_transfer_full_duplex_blocking(uint8_t *tx_data, uint8_t *rx_data, uint16_t size)

Read and Write data full duplex on the radio in blocking mode.

Parameters:

  • tx_data – [in] Data buffer to write.

  • rx_data – [out] Data received.

  • size – [in] Size of the data.

void evk_radio_spi_transfer_full_duplex_non_blocking(uint8_t *tx_data, uint8_t *rx_data, uint16_t size)

Read and Write data full duplex on the radio in non-blocking mode.

Parameters:

  • tx_data – [in] Data buffer to write.

  • rx_data – [out] Data received.

  • size – [in] Size of the data.

bool evk_radio_is_spi_busy(void)

Read the status of the radio’s SPI.

Return values:

  • true – SPI is busy.

  • false – SPI is not busy.

void evk_radio_context_switch(void)

Software interrupt trigger to force the cpu to get into the interrupt handler.

void evk_radio_callback_context_switch(void)

Induce a context switch to the pendSV ISR.

void evk_radio_set_spi_baudrate(spi_prescaler_t prescaler)

Change the radio’s SPI BaudRate.

Note

The evk_init() function does initialize by default the SPI peripheral with a prescaler of 4.

Parameters:

prescaler – [in] SPI BaudRate Prescaler.
