README
======
README for NuttX port to NRF52832-DK (PCA10040) boards.
Contents
========
- Status
- NRF52832 development kit (PCA10040)
- Configurations
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.
NRF52832 development kit (PCA10040)
===================================
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-TX P0.06
UART0-RX P0.08
LEDs
----
The PCA10040 has 4 user-controllable LEDs
LED MCU
LED1 PIN0-17
LED2 PIN0-18
LED3 PIN0-19
LED4 PIN0-20
A low output illuminates the LED.
Pushbuttons
-----------
To be provided
Memory Map
==========
Block Start Length
Name Address
--------------------- ---------- ------
FLASH 0x00000000 512K
RAM 0x20000000 64K
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:
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.
wdog:
------------
This configuration is a simple NSH-based test of the nRF52 watchdog
timer driver using the test at apps/examples/watchdog.
CONFIG_ARCH_LEDS
----------------
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);
