Console
|

-------
|
|
|
|
The PCA10040 default console is the UART0.

|
Status
|
|
======
|
|
|
|
This is the current status of the NRF52 port:
|
|
|
|
- The basic OS test configuration and the basic NSH configurations
|
|
are present and fully verified. This includes: SYSTICK system time,
|
|
pin and GPIO configuration, and serial console support.
|
|
|
|
LED and Pushbuttons
|
|
===================
|
|
|
|
LEDS
|
|
----
|
|
The PCA10040 has 4 user-controllable LEDs
|
|
|
|
LED MCU
|
|
LED1 PIN-17
|
|
LED2 PIN-18
|
|
LED3 PIN-19
|
|
LED4 PIN-20
|
|
|
|
A low output illuminates the LED.
|
|
|
|
If CONFIG_ARCH_LEDS is defined, the LED will be controlled as follows
|
|
for NuttX debug functionality (where NC means "No Change").
|
|
|
|
TBD!
|
|
|
|
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:
|
|
|
|
void board_userled_initialize(void);
|
|
void board_userled(int led, bool ledon);
|
|
void board_userled_all(uint8_t ledset);
|
|
|
|
Pushbuttons

Serial Console
|
|
==============
|
|
|
|
The PCA10040 does not have RS-232 drivers or serial connectors on board.
|
|
UART0, is available on P4 as follows:
|
|
|
|
-------- -----
|
|
Signal PIN
|
|

|
|
UART0-TX P0.24
|
|
UART0-RX P0.23
|
|
|
|
Configurations
|
|
==============
|
|
|
|
Each PCA10040 configuration is maintained in a sub-directory and can be selected
|
|
as follow:
|
|
|
|
tools/configure.sh nrf52-pca10040/<subdir>
|
|
|
|
Where <subdir> is one of the following:
|
|
|
|
nsh:
|
|
----
|
|
This configuration is the NuttShell (NSH) example at examples/nsh/.
|
|
|
|
NOTES:
|
|
|
|
1. This configuration uses the mconf-based configuration tool. To
|
|
change this configurations using that tool, you should:
|
|
|
|
a. Build and install the kconfig-mconf tool. See nuttx/README.txt
|
|
see additional README.txt files in the NuttX tools repository.
|
|
|
|
b. Execute 'make menuconfig' in nuttx/ in order to start the
|
|
reconfiguration process.

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