Function Documentation

◆ at86rf215_arch_init()

void at86rf215_arch_init ( void )

Initialize the radio's I/O periphery.

The function has to accomplish the following tasks:

Configure RST pin
Configure IRQ pin and setup the interrupt
Configure CSn pin
Enable and configure SPI

◆ at86rf215_arch_set_RSTN()

void at86rf215_arch_set_RSTN ( void )

Reset the radio.

The radio Reset is triggered by pulling the pin RSTN to low, keeping it low for 625ns and than release it to high.

◆ at86rf215_arch_spi_txrx()

uint8_t at86rf215_arch_spi_txrx ( uint8_t b )

Transfer and receive a single byte over SPI.

Parameters

b	Byte to be sent

Returns: Byte received

◆ at86rf215_isr()

void at86rf215_isr ( void )

Interrupt routine.

To be called by the hardware interrupt handler - part of at86rf215-arch.c

Interrupt routine.

This function is called by the GPIO interrupt handler. The interrupt can be triggered by the radio (RF) or the baseband part (BBC). Depending on the predefined frequency band, correct register addresses are used to read the interrupt states. The states are then used to set the corresponding flags. To clear the IRQ line, all 4 interrupts registers must be read.
