|
||||
|
||||
The LPCXpresso 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").
|
||||
The LPCXpresso LPC1768 has a single LEDs (there are more on the Embedded Artists
|
||||
base board, but those are not controlled by NuttX). Usage this single LED by NuttX
|
||||
is as follows:
|
||||
|
||||
During the boot phases. LED1 and LED2 will show boot status.
|
||||
- The LED is not illuminated until the LPCXpresso completes initialization.
|
||||
|
||||
If the LED is stuck in the OFF state, this means that the LPCXpresso did not
|
||||
complete intialization.
|
||||
|
||||
/* 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 */
|
||||
- Each time the OS enters an interrupt (or a signal) it will turn the LED OFF and
|
||||
restores its previous stated upon return from the interrupt (or signal).
|
||||
|
||||
#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 (0.5Hz flashing) */
|
||||
#undef LED_IDLE /* Sleep mode indication not supported */
|
||||
The normal state, after initialization will be a dull glow. The brightness of
|
||||
the glow will be inversely related to the proportion of time spent within interrupt
|
||||
handling logic. The glow may decrease in brightness when the system is very
|
||||
busy handling device interrupts and increase in brightness as the system becomes
|
||||
idle.
|
||||
|
||||
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():
|
||||
Stuck in the OFF state suggests that that the system never completed
|
||||
initialization; Stuck in the ON state would indicated that the system
|
||||
intialialized, but is not takint interrupts.
|
||||
|
||||
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.
|
||||
- If a fatal assertion or a fatal unhandled exception occurs, the LED will flash
|
||||
strongly as a slow, 1Hz rate.
