config GENERICRADIO_UPPER
	bool "Build the upper half driver (access generic radios as char devices)"
	default n
	---help---
		This selection enables support for the upper half character driver to access
		the generic radios.

config GENERICRADIO_SI4463
	bool "Silabs SI4463 transceiver (used in HopeRF RFM26, 433/868/915 MHz)"
	default n
	depends on SPI
	---help---
		This selection enables support for the SiLabs SI4463 / HopeRF RFM26 device.

config GENERICRADIO_SI4463_ANTSWITCH_ALT
  bool "Alternate TX/RX switching using dedicated GPIO setup"
  default n
  ---help---
    The si4463 has the ability to drive GPIO pins to activate PA/LNA, but these are only active high,
    with no internal way to invert the signals. If inverted signals are required, and you cant invert
    the signals with external hardware, use this option, but be aware that TX/RX switching time will
    be slower since a GPIO setup command has to be sent via before/after each transmission and reception.

config GENERICRADIO_SI4463_USE_WDS_CONFIG
  bool "Use a canned WDS config in drivers/wireless/generic/si4463_config.h"
  default n
  ---help---
    This loads the RF configuration from a file generated by Silabs WDS.
    (This file is not provided in nuttx, you have to generate it yourself)
    The config is applied at initialization time. After this any command
    to change the current config will do it regardless of the settings that
    were defined by the WDS header.
    This feature can be used for faster driver development while all configuration
    algorithms have not been sorted out yet.

config GENERICRADIO_SI4463_DEFAULT_FREQ
  int "Default frequency (in Hz)"
  default 0
  depends on !GENERICRADIO_SI4463_USE_WDS_CONFIG

  int "Default data rate (in bits/second)"
  default 10000
  depends on !GENERICRADIO_SI4463_USE_WDS_CONFIG
  ---help---
    This sets a data rate at device initialization

config GENERICRADIO_SI4463_DEFAULT_DEV
  int "Default FSK deviation (in Hz)"
  default 10000
  depends on !GENERICRADIO_SI4463_USE_WDS_CONFIG
  ---help---
    This sets a deviation at device initialization

config GENERICRADIO_SI4463_DEFAULT_CHSPC
  int "Default channel spacing (in Hz/1000)"
  default 100000000
  depends on !GENERICRADIO_SI4463_USE_WDS_CONFIG

    This sets a channel spacing at device initialization

  depends on !GENERICRADIO_SI4463_USE_WDS_CONFIG
