LEDs
====
The PIC32MX Ethernet Starter kit has 3 user LEDs labeled LED1-3 on the
board graphics (but referred to as LED4-6 in the schematic):
PIN User's Guide Board Stencil Notes
--- ------------- -------------- -------------------------
RD0 "User LED D4" "LED1 (RD0") High illuminates (RED)
RD2 "User LED D5" "LED3 (RD2)" High illuminates (YELLOW)
RD1 "User LED D6" "LED2 (RD1)" High illuminates (GREEN)
We will use the labels on the board to identify LEDs. If CONFIG_ARCH_LEDS
is defined, then NuttX will control these LEDs as follows:
ON OFF
------------------------- ---- ---- ---- ---- ---- ----
LED1 LED2 LED3 LED1 LED2 LED3
------------------------- ---- ---- ---- ---- ---- ----
LED_STARTED 0 OFF OFF OFF --- --- ---
LED_HEAPALLOCATE 1 ON OFF N/C --- --- ---
LED_IRQSENABLED 2 OFF ON N/C --- --- ---
LED_STACKCREATED 3 ON ON N/C --- --- ---
LED_INIRQ 4 N/C N/C ON N/C N/C OFF
LED_SIGNAL 4 N/C N/C ON N/C N/C OFF
LED_ASSERTION 4 N/C N/C ON N/C N/C OFF
LED_PANIC 5 ON N/C N/C OFF N/C N/C
There are 5 additional LEDs available on the MEB. These are not
used by NuttX.

RD2 LED2
RD3 LED3
