LEDs
====
The Open1788 base board has four user LEDs
LED1 : Connected to P1[14]
LED2 : Connected to P0[16]
LED3 : Connected to P1[13]
LED4 : Connected to P4[27]
If CONFIG_ARCH_LEDS is not defined, then the user can control the LEDs in
any way using the defitions provided in the board.h header file.
If CONFIG_ARCH_LEDs is defined, then NuttX will control the 3 LEDs on the
WaveShare Open1788K. The following definitions describe how NuttX controls
the LEDs:
LED1 LED2 LED3 LED4
LED_STARTED OFF OFF OFF OFF
LED_HEAPALLOCATE ON OFF OFF OFF
LED_IRQSENABLED OFF ON OFF OFF
LED_STACKCREATED ON ON OFF OFF
LED_INIRQ LED3 glows, on while in interupt
LED_SIGNAL LED3 glows, on while in signal handler
LED_ASSERTION LED3 glows, on while in assertion
LED_PANIC LED3 Flashes at 2Hz
LED_IDLE LED glows, ON while sleeping
Buttons
=======
The Open1788K supports several buttons:
USER1 : Connected to P4[26]
USER2 : Connected to P2[22]
USER3 : Connected to P0[10]
And a Joystick
JOY_A : Connected to P2[25]
JOY_B : Connected to P2[26]
JOY_C : Connected to P2[23]
JOY_D : Connected to P2[19]
JOY_CTR : Connected to P0[14]
These can be accessed using the definitions and interfaces defined in the
board.h header file.
