nRF52832-DK

chip:nrf52, chip:nrf52832

The NRF52832-DK (PCA10040) is a development board for the nRF52832 SoC from Nordic.

Serial Console

The PCA10040 default console is the UART0.

The PCA10040 does not have RS-232 drivers or serial connectors on board. UART0 is connected to the virtual COM port:

LEDs and Buttons

LEDs

The PCA10040 has 4 user-controllable LEDs:

LED MCU

---

LED1 P0.17 LED2 P0.18 LED3 P0.19 LED4 P0.20

A low output illuminates the LED.

CONFIG_ARCH_LEDS

If CONFIG_ARCH_LEDS is not defined, then the LEDs are completely under control of the application. The following interfaces are then available for application control of the LEDs:

uint32_t board_userled_initialize(void);
void board_userled(int led, bool ledon);
void board_userled_all(uint32_t ledset);

Pushbuttons

Configurations

Each configuration is maintained in a sub-directory and can be selected as follow:

tools/configure.sh nrf52832-dk:<subdir>

Where <subdir> is one of the following:

jumbo

This configuration enables many Apache NuttX features. This is mostly to help provide additional code coverage in CI, but also allows for a users to see a wide range of features that are supported by the OS.

nsh

Basic NuttShell configuration (console enabled in UART0, exposed via J-Link VCOM connection, at 115200 bps).

ostest_tickless

This is a NSH configuration that includes apps/testing/ostest as a builtin and enable support for the tick-less OS.

sdc

Enables Nordic's SoftDevice controller and uses NuttX BLE stack for the host-layer. The btsak application is included as a builtin.

sdc_nimble

Enables Nordic's SoftDevice controller and uses nimBLE for the host-layer. The nimble test application can be used to enable a simple GATT server.
