^^^^
|

|
|
||||||
|
If CONFIG_ARCH_LEDS is defined, then support for the Nucleus-2G LEDs will be
|
||||||
|
included in the build. See:
|
||||||
|
|
||||||
|
- configs/nucleus2g/include/board.h - Defines LED constants, types and
|
||||||
|
prototypes the LED interface functions.
|
||||||
|
|
||||||
|
- configs/nucleus2g/src/nucleus2g_internal.h - GPIO settings for the LEDs.
|
||||||
|
|
||||||
|
- configs/nucleus2g/src/up_leds.c - LED control logic.
|
||||||
|
|
||||||
|
The Nucleus2G has 3 LEDs... two on the Babel CAN board and a "heartbeat" LED."
|
||||||
|
The LEDs on the Babel CAN board are capabl of OFF/GREEN/RED/AMBER status.
|
||||||
|
In normal usage, the two LEDs on the Babel CAN board would show CAN status, but if
|
||||||
|
CONFIG_ARCH_LEDS is defined, these LEDs will be controlled as follows for NuttX
|
||||||
|
debug functionality (where NC means "No Change").
|
||||||
|
|
||||||
|
During the boot phases. LED1 and LED2 will show boot status.
|
||||||
|
|
||||||
|
/* LED1 LED2 HEARTBEAT */
|
||||||
|
#define LED_STARTED 0 /* OFF OFF OFF */
|
||||||
|
#define LED_HEAPALLOCATE 1 /* GREEN OFF OFF */
|
||||||
|
#define LED_IRQSENABLED 2 /* OFF GREEN OFF */
|
||||||
|
#define LED_STACKCREATED 3 /* OFF OFF OFF */
|
||||||
|
|
||||||
|
#define LED_INIRQ 4 /* NC NC ON (momentary) */
|
||||||
|
#define LED_SIGNAL 5 /* NC NC ON (momentary) */
|
||||||
|
#define LED_ASSERTION 6 /* NC NC ON (momentary) */
|
||||||
|
#define LED_PANIC 7 /* NC NC ON (1Hz flashing) */
|
||||||
|
|
||||||
|
After the system is booted, this logic will no longer use LEDs 1 and 2. They
|
||||||
|
are then available for use the application software using lpc17_led1() and
|
||||||
|
lpc17_led2():
|
||||||
|
|
||||||
|
enum lpc17_ledstate_e
|
||||||
|
{
|
||||||
|
LPC17_LEDSTATE_OFF = 0,
|
||||||
|
LPC17_LEDSTATE_GREEN = 1,
|
||||||
|
LPC17_LEDSTATE_RED = 2,
|
||||||
|
LPC17_LEDSTATE_AMBER = (LPC17_LEDSTATE_GREEN|LPC17_LEDSTATE_RED),
|
||||||
|
};
|
||||||
|
|
||||||
|
EXTERN void lpc17_led1(enum lpc17_ledstate_e state);
|
||||||
|
EXTERN void lpc17_led2(enum lpc17_ledstate_e state);
|
||||||
|
|
||||||
|
The heartbeat LED is illuminated during all interrupt and signal procressing.
|
||||||
|
Normally, it will glow dimly to inicate that the LPC17xx is taking interrupts.
|
||||||
|
On an assertion PANIC, it will flash at 1Hz.
