2018-02-10: Added the nxlines configuration to test the custom HiletGo
OLED on a Click proto board. Debug output indicates that the example is
running error free yet nothing appears on the OLED in mikroBUS slot A.
It looks like all of the signals are present at the mikroBUS A slot and
the proto click ohms out okay so this must be a software driver issue.
Write only LCDs are tough to debug!
I tried slot D with same result. I also ported the configuration to
the Flip&Click SAM3X and got the same result. There could be SPI issues
on the PIC32MX, but more likely that there is an error in my custom
HiletGo Click. Damn!

The HiletGo is a 128x64 OLED that can be driven either via SPI or I2C (SPI
is the default and is what is used here). I have mounted the OLED on a

This is an NSH configuration that supports the NX graphics example at
apps/examples/nxlines as a built-in application.
NOTES:
1. This configuration derives from the nsh configuration. All of the
notes there apply here as well.
2. The default configuration assumes there is the custom HiletGo OLED
in the mikroBUS B slot (and a Mikroe RS-232 Click card in the
mikroBUS A slot). That is easily changed by reconfiguring, however.
See the section entitled "HiletGo OLED" for information about this
custom click card.

* 1. Provide logic in sam_boardinitialize() to configure SPI chip select
* pins.
* 2. Provide sam_spi0select() and sam_spi0status() 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_spic0mddata() 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 sam_spibus_initialize() in your low level application
* initialization logic
* 4. The handle returned by sam_spibus_initialize() 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_spi0select
*
* 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
* 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
* same as the NPCS pin normal associated with the chip select number.
*
* Input Parameters:
* devid - Identifies the (logical) device
* selected - TRUE:Select the device, FALSE:De-select the device
*
* Returned Value:
* None

* Name: sam_spi0cmddata
*
* Description:
* Some SPI devices require an additional control to determine if the SPI
* data being sent is a command or is data. If CONFIG_SPI_CMDDATA then
* this function will be called to different be command and data transfers.
*
* This is often needed, for example, by LCD drivers. Some LCD hardware
* may be configured to use 9-bit data transfers with the 9th bit
* indicating command or data. That same hardware may be configurable,
* instead, to use 8-bit data but to require an additional, board-
* specific PIO control to distinguish command and data. This function
* would be needed in that latter case.
*
* Input Parameters:
* dev - SPI device info
* devid - Identifies the (logical) device
*
* Returned Value:
* Zero on success; a negated errno on failure.
