Crate nrf52840dk_lib

Tock kernel for the Nordic Semiconductor nRF52840 development kit (DK).

It is based on nRF52840 SoC (Cortex M4 core with a BLE transceiver) with many exported I/O and peripherals.

Supported drivers by the platform

Constants

NUM_PROCS

Number of concurrent processes this platform supports.

Functions

ieee802154_udp^⚠

Create the capsules needed for the in-kernel UDP and 15.4 stack.

start^⚠

This is in a separate, inline(never) function so that its stack frame is removed when this function returns. Otherwise, the stack space used for these static_inits is wasted.

start_no_pconsole^⚠

This is in a separate, inline(never) function so that its stack frame is removed when this function returns. Otherwise, the stack space used for these static_inits is wasted.

Type Aliases

ChipHw

This platform’s chip type:

Eui64Driver

Userspace EUI64 driver.

Ieee802154Driver

Userspace 802.15.4 driver with in-kernel packet framing and MAC layer.
