arch/nrf52: add initial support for IEEE 802.15.4
Supported features: - frame transmition - frame reception and filtering - immediate ACK (incoming and outgoing) - promiscuous mode - delayed transmision - radio events trace - setting pending bit for all incoming Data Request frames - un-slotted CSMA-CA Work in progres features (some logic is present, but they require more work): - beacon transmision (periodic transmition works, but requires verification) - slotted CSMA-CA - GTS Fetures not implemented: - enhanced ACK (Enh-ACK) - enhanced beacon - low power mode - advanced features from IEEE 802.15.4e (DSME, TSCH) Added examples for boards: - nrf52832-dk: mrf24j40_6lowpan - nrf52832-dk: mrf24j40_mac - nrf52840-dk: ieee802154_6lowpan - nrf52840-dk: ieee802154_mac - nrf52840-dongle: ieee802154_mac - nrf9160-dk-nrf52: ieee802154_6lowpan - nrf9160-dk-nrf52: ieee802154_mac

Nordic nRF52 IEEE 802.15.4
|
||||
==========================
|
||||
|
||||
.. note::
|
||||
|
||||
This driver is highly experimental.
|
||||
Help with development and testing will be appreciated ;)
|
||||
|
||||
Supported features:
|
||||
|
||||
* frame transmission
|
||||
* frame reception and filtering
|
||||
* immediate ACK (incoming and outgoing)
|
||||
* promiscuous mode
|
||||
* delayed transmision
|
||||
* radio events trace
|
||||
* setting pending bit for all incoming Data Request frames
|
||||
* un-slotted CSMA-CA
|
||||
|
||||
Work in progres features (some logic is present, but they require more work):
|
||||
|
||||
* beacon transmision (periodic transmition works, but requires verification)
|
||||
* slotted CSMA-CA
|
||||
* GTS
|
||||
|
||||
Fetures not implemented:
|
||||
|
||||
* enhanced ACK (Enh-ACK)
|
||||
* enhanced beacon
|
||||
* low power mode
|
||||
* advanced features from IEEE 802.15.4e (DSME, TSCH)
|
||||
|
||||
Reserved peripherals
|
||||
====================
|
||||
|
||||
This implementation reserves the following peripherals:
|
||||
|
||||
* ``RADIO`` - used for radio operations
|
||||
|
||||
* ``TIMER0`` - used as high resolution timer for ACK, IFS and other radio delays
|
||||
|
||||
* ``RTC0`` - if superframe support is enabled, used as low power timer to hande
|
||||
superframe events

|
||||
* All other methods (including nrf52_spibus_initialize()) are provided
|
||||
* by common NRF52 logic. To use this common SPI logic on your board:
|
||||
*
|
||||
* 1. Provide logic in nrf52_boardinitialize() to configure SPI chip select
|
||||
* pins.
|
||||
* 2. Provide nrf52_spi0/1/2/3select() and nrf52_spi0/1/2/3status()
|
||||
* functions in your board-specific logic. These functions will perform
|
||||
* chip selection and status operations using GPIOs in the way your
|
||||
* board is configured.
|
||||
* 3. Add a calls to nrf52_spibus_initialize() in your low level
|
||||
* application initialization logic
|
||||
* 4. The handle returned by nrf52_spibus_initialize() may then be used to
|
||||
* bind the SPI driver to higher level logic (e.g., calling
|
||||
* mmcsd_spislotinitialize(), for example, will bind the SPI driver to
|
||||
* the SPI MMC/SD driver).
