Default SPI Interface

Default SPI Interface

• Depends on CONFIG_SSD1306_ENABLE_DEFAULT_SPI_INTERFACE
• Default host is HSPI
• Default frequency is 1MHz
• Default MOSI pin is 13
• Default SCLK pin is 14
• Default DC pin is 33

This provides a quick and easy way to get an SPI attached display up and running.
Default SPI options are configured in the tarablesssd1306 component config menu.

SSD1306_SPIMasterInitDefault:

bool SSD1306_SPIMasterInitDefault( void )

Initializes the SPI host as configured in the component config menu.

Returns:

• True: Successfully initialized SPI host

SPIMasterAttachDisplayDefault:

bool SSD1306_SPIMasterAttachDisplayDefault( struct SSD1306_Device* DeviceHandle, int Width, int Height, int CSForThisDisplay, int RSTForThisDisplay )

Initializes the display and attaches it to the SPI bus.

Parameters:

1. Pointer to an object to use as a display handle
2. Width of the display
3. Height of the display
4. GPIO Pin number of the chip select pin
5. GPIO Pin number for the reset pin (Optional: If you're not using the reset pin, pass -1)

Returns:

• True if the display was attached properly

NOTE: Since this display can be used write only, we can only assume it's properly connected
thus this will still return true even if there is a problem communicating with the device.
