LEDs and Buttons
================
LEDs
----
The launchpad has a four LEDs two power LEDs labeled D1 (red) that
connects to the TMS570's NERROR pin and D7 (blue) that indicates the
XDS200 POWER_EN signal, and two white, user LEDs labeled D12 that
connects to the NHET08 pin and D11 that connects to GIOA2.
NHET08 is one of 32 N2HET pins than can be available to the user if
not used by N2HET. This implementation, however, uses only the single
LED driven by GIOA2. That LED is tied to ground and illuminated
with a high level output value.
This LED is not used by the board port unless CONFIG_ARCH_LEDS is
defined. In that case, the usage by the board port is defined in
include/board.h and src/tms570_autoleds.c. The LED is used to encode
OS-related events as follows:
------------------- ----------------------- ------
SYMBOL Meaning LED
------------------- ----------------------- ------
LED_STARTED NuttX has been started OFF
LED_HEAPALLOCATE Heap has been allocated OFF
LED_IRQSENABLED Interrupts enabled OFF
LED_STACKCREATED Idle stack created ON
LED_INIRQ In an interrupt N/C
LED_SIGNAL In a signal handler N/C
LED_ASSERTION An assertion failed N/C
LED_PANIC The system has crashed FLASH
Thus if the LED is statically on, NuttX has successfully booted and is,
apparently, running normally. If the LED is flashing at approximately
2Hz, then a fatal error has been detected and the system has halted.
Buttons
-------
The launchpad has three mechanical buttons. Two of these are reset buttons:
One button is labeled PORRST performs a power-on reset and one labeled RST
performs an MCU reset. Only one button is available for general software
usage. That button is labeled GIOA7 and is, obviously, sensed on GIOA7.
GIOA7 is tied to ground, but will be pulled high if the GIOA7 button is
depressed.
