/* There are three LEDs on board the SAML21 Xplained Pro board: The EDBG
|
||||
* controls two of the LEDs, a power LED and a status LED. There is only
|
||||
* one user controllable LED, a yellow LED labelled STATUS near the SAML21 USB
|
||||
* connector.
|
||||
*
|
||||
* This LED is controlled by PA14 and the LED can be activated by driving PA14
|
||||
* to GND.
|
||||
*
|
||||
* When CONFIG_ARCH_LEDS is defined in the NuttX configuration, NuttX will
|
||||
* control the LED as follows:
|
||||
*
|
||||
* SYMBOL Meaning LED
|
||||
* ------------------- ----------------------- ------
|
||||
* LED_STARTED NuttX has been started OFF
|

* LED_IRQSENABLED Interrupts enabled OFF

* LED_STACKCREATED Idle stack created ON

* LED_ASSERTION An assertion failed N/C

* LED_PANIC The system has crashed FLASH

* apparently, running normally. If the LED is flashing at approximately
|
||||
* 2Hz, then a fatal error has been detected and the system has halted.

* These external functions must be provided by board-specific logic. They
|
||||
* include:
|
||||
*
|
||||
* o sam_spi[n]select is a functions to manage the board-specific chip
|
||||
* selects
|
||||
* o sam_spi[n]status and sam_spi[n]cmddata: Implementations of the status
|
||||
* and cmddata methods of the SPI interface defined by struct spi_ops_
|
||||
* (see include/nuttx/spi/spi.h). All other methods including
|
||||
* up_spiinitialize()) are provided by common SAMD/L logic.
|
||||
*
|
||||
* Where [n] is the SERCOM number for the SPI module.
|
||||
*
|
||||
* To use this common SPI logic on your board:
|
||||
*
|
||||
* 1. Provide logic in sam_boardinitialize() to configure SPI chip select
|
||||
* pins.
|
||||
* 2. Provide sam_spi[n]select() and sam_spi[n]status() functions in your
|
||||
* board-specific logic. These functions will perform chip selection
|
||||
* and status operations using GPIOs in the way your board is configured.
|
||||
* 2. If CONFIG_SPI_CMDDATA is defined in the NuttX configuration, provide
|
||||
* sam_spi[n]cmddata() functions in your board-specific logic. This
|
||||
* function will perform cmd/data selection operations using GPIOs in
|
||||
* the way your board is configured.
|
||||
* 3. Add a call to up_spiinitialize() in your low level application
|
||||
* initialization logic
|
||||
* 4. The handle returned by up_spiinitialize() may then be used to bind
|
||||
* the SPI driver to higher level logic (e.g., calling
|
||||
* mmcsd_spislotinitialize(), for example, will bind the SPI driver to
|
||||
* the SPI MMC/SD driver).

*
|

* Description:
|

* PIO chip select pins may be programmed by the board specific logic in

* peripherals. In that case, the pins are completely controlled by the

* SPI driver. This method still needs to be provided, but it may be only
|

* a stub.
|

*
|
||||
* An alternative way to program the PIO chip select pins is as a normal
|
||||
* GPIO output. In that case, the automatic control of the CS pins is
|
||||
* bypassed and this function must provide control of the chip select.
|
||||
* NOTE: In this case, the GPIO output pin does *not* have to be the

/* LEDs: There are three LEDs on board the SAML21 Xplained Pro board: The EDBG
|
||||
* controls two of the LEDs, a power LED and a status LED. There is only
|
||||
* one user controllable LED, a yellow LED labelled STATIS near the SAML21 USB
|
||||
* connector.
|
||||
*
|
||||
* This LED is controlled by PA14 and the LED can be activated by driving PA14
|
||||
* to GND.
|
||||
*
|
||||
* When CONFIG_ARCH_LEDS is defined in the NuttX configuration, NuttX will
|
||||
* control the LED 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.
