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.
