/* The Freedom K64F has a single RGB LED driven by the K64F as follows:
|
|
*
|
|
* LED K64
|
|
* ------ -------------------------------------------------------
|
|
* RED PTB22/SPI2_SOUT/FB_AD29/CMP2_OUT
|
|
* BLUE PTB21/SPI2_SCK/FB_AD30/CMP1_OUT
|
|
* GREEN PTE26/ENET_1588_CLKIN/UART4_CTS_b/RTC_CLKOUT/USB0_CLKIN
|
|
*
|
|
* If CONFIG_ARCH_LEDs is defined, then NuttX will control the LED on board
|
|
* the Freedom K64F. The following definitions describe how NuttX controls
|
|
* the LEDs:
|
|
*
|
|
* SYMBOL Meaning LED state
|
|
* RED GREEN BLUE
|
|
* ------------------- ----------------------- -----------------
|
|
* LED_STARTED NuttX has been started OFF OFF OFF
|
|
* LED_HEAPALLOCATE Heap has been allocated OFF OFF ON
|
|
* LED_IRQSENABLED Interrupts enabled OFF OFF ON
|
|
* LED_STACKCREATED Idle stack created OFF ON OFF
|
|
* LED_INIRQ In an interrupt (no change)
|
|
* LED_SIGNAL In a signal handler (no change)
|
|
* LED_ASSERTION An assertion failed (no change)
|
|
* LED_PANIC The system has crashed FLASH OFF OFF
|
|
* LED_IDLE K64 is in sleep mode (Optional, not used)
