Detailed Description

SX1272/6 radio driver.

Macro Definition Documentation

#define RADIO_OSC_STARTUP   1

Radio wakeup time from SLEEP mode

#define RADIO_SLEEP_TO_RX   2

Radio PLL lock and Mode Ready delay which can vary with the temperature

#define RADIO_WAKEUP_TIME   (RADIO_OSC_STARTUP + RADIO_SLEEP_TO_RX)

Radio complete Wake-up Time with margin for temperature compensation

Function Documentation

void os_radio

(

uint8_t

mode

)

Changes the radio mode.

Parameters

mode	The mode in which the radio will be put. This can be RADIO_RST, RADIO_TX, RADIO_RX, or RADIO_RXON.

void radio_irq_handler

(

uint8_t

dio

)

The radio driver IRQ handler.

Parameters

dio	The INT number to handle.

uint8_t radio_rand1

(

void

)

Returns a random byte.

Return values

uint8_t

A random byte.

uint8_t radio_read

(

uint8_t

reg

)

Reads a radio register.

The function reads the value of a specific SX127x register.

Parameters

reg	The register to read from.

Return values

uint8_t

The value read.

void radio_reset

(

uint8_t

val

)

Resets the SX127x module.

Parameters

val	1 to put the radio in reset, 0 to release the reset.

uint8_t radio_rssi

(

void

)

Returns the current RSSI.

The function returns the current RSSI in dBm + 157 dBm. The SX127x has to be in RX mode.

Return values

uint8_t

The RSSI read.

void radio_write	(	uint8_t	addr,
		uint8_t	data
	)

Writes a radio register.

The function writes a value to a specific SX127x register.

Parameters

addr	The register to write to.
data	The value to write.
