nRF52832-DK

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:

Signal	PIN
UART0-RX	P0.08
UART0-TX	P0.06

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

BUTTON	MCU
BUTTON1	P0.13
BUTTON2	P0.14
BUTTON3	P0.15
BUTTON4	P0.16

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:

buttons

This configuration shows the use of the buttons subsystem.

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.

wdog

This configuration is a simple NSH-based test of the nRF52 watchdog timer driver using the test at apps/examples/watchdog.
