Semtech sx1280 zephyr driver

[dvalnn]

Is there any Zephyr driver available for the sx128x family?
What would it be required to port the sx128x radio?

I ported the sx128x driver from LBM. All you need to do is adapt the hal mcu (spi and gpios) for the Zephyr.

I have not managed to find the 128x driver in this repository...
Do you have a link where I could find the port you are talking?

I realize those drivers exist. I want to understand what is and is not ported for Zephyr in this repository.

looking at this Kconfig snippet,

LBM_Zephyr/drivers/lora_lbm/Kconfig.sx12xx

Lines 22 to 28 in f2c9d88

	config SEMTECH_SX128X
	bool "Semtech SX128x family LoRa transceiver driver"
	default y
	depends on DT_HAS_SEMTECH_SX1280_NEW_ENABLED || DT_HAS_SEMTECH_SX1281_NEW_ENABLED
	select SPI
	help
	Enable driver for the SX128x family LoRa transceiver driver

There are options defined for all radios of the sx12xx family. However, I can only find devicetree bindings and driver implementations for the sx126x boards.

From this, I understand that to use the sx1280 radio, I would have to provide the missing bindings and hal implementations, similar to what was done here for the sx126x family.

I ported the sx128x driver from LBM. All you need to do is adapt the hal mcu (spi and gpios) for the Zephyr.

Is that what you mean here? Or am I missing something and only need to implement the 4 Hal functions?

Do you have any more information on this?

Hi,
SX128x is not yet currently ported on LBM ZEPHYR. This could be available in a future release.
