/* There are two LEDs on the SAMA5D4 series-CM board that can be controlled
|
||||
* by software. A blue LED is controlled via PIO pins. A red LED normally
|
||||
* provides an indication that power is supplied to the board but can also
|
||||
* be controlled via software.
|
||||
*
|
||||
* PE25. This blue LED is pulled high and is illuminated by pulling PE25
|
||||
* low.
|
||||
*
|
||||
* PE24. The red LED is also pulled high but is driven by a transistor so
|
||||
* that it is illuminated when power is applied even if PE24 is not
|
||||
* configured as an output. If PE24 is configured as an output, then the
|
||||
* LCD is illuminated by a low output.
|
||||
*
|
||||
* These LEDs are not used by the board port unless CONFIG_ARCH_LEDS is
|
||||
* defined. In that case, the usage by the board port is defined in
|
||||
* include/board.h and src/sam_leds.c. The LEDs are used to encode OS-related
|
||||
* events as follows:
|
||||
*
|
||||
* SYMBOL Val Meaning LED state
|
||||
* Blue Red
|
||||
* ----------------- --- ----------------------- -------- --------
|
||||
* LED_STARTED 0 NuttX has been started OFF OFF
|
||||
* LED_HEAPALLOCATE 0 Heap has been allocated OFF OFF
|
||||
* LED_IRQSENABLED 0 Interrupts enabled OFF OFF
|
||||
* LED_STACKCREATED 1 Idle stack created ON OFF
|
||||
* LED_INIRQ 2 In an interrupt No change
|
||||
* LED_SIGNAL 2 In a signal handler No change
|
||||
* LED_ASSERTION 2 An assertion failed No change
|
||||
* LED_PANIC 3 The system has crashed OFF Blinking
|
||||
* LED_IDLE N/A MCU is is sleep mode Not used
|
||||
*
|
||||
* Thus if the blue LED is statically on, NuttX has successfully booted and
|
||||
* is, apparently, running normally. If the red is flashing at
|
||||
* approximately 2Hz, then a fatal error has been detected and the system
|
||||
* has halted.

* Description:
|

* These external functions must be provided by board-specific logic. They
|
||||
* include:
|
||||
*
|
||||
* o sam_spi[0|1]select is a functions tomanage the board-specific chip selects
|
||||
* o sam_spi[0|1]status and sam_spi[0|1]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 SAM3/4 logic.
|
||||
*
|
||||
* 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[0|1]select() and sam_spi[0|1]status() functions in your board-
|
||||
* specific logic. These functions will perform chip selection and
|
||||
* status operations using PIOs in the way your board is configured.
|
||||
* 2. If CONFIG_SPI_CMDDATA is defined in the NuttX configuration, provide
|
||||
* sam_spi[0|1]cmddata() functions in your board-specific logic. This
|
||||
* function will perform cmd/data selection operations using PIOs 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).

* Name: sam_spi[0|1]select
|

*
|
||||
* Description:
|
||||
* PIO chip select pins may be programmed by the board specific logic in
|
||||
* one of two different ways. First, the pins may be programmed as SPI
|
||||
* 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
|
||||
* PIO 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 PIO output pin does *not* have to be the
|
||||
* same as the NPCS pin normal associated with the chip select number.
|
||||
*
|

* Input Parameters:

/* There are two LEDs on the SAMA5D4 series-CM board that can be controlled
|
||||
* by software. A blue LED is controlled via PIO pins. A red LED normally
|
||||
* provides an indication that power is supplied to the board but can also
|
||||
* be controlled via software.
|
||||
*
|
||||
* PE25. This blue LED is pulled high and is illuminated by pulling PE25
|
||||
* low.
|
||||
*
|
||||
* PE24. The red LED is also pulled high but is driven by a transistor so
|
||||
* that it is illuminated when power is applied even if PE24 is not
|
||||
* configured as an output. If PE24 is configured as an output, then the
|
||||
* LCD is illuminated by a low output.
