#define CONF_HX8347A_BACKLIGHT_PIN   DISPLAY_XPLAINED_BACKLIGHT

Define what MCU pin the HX8347A back light pin is connected to.

Referenced by hx8347a_backlight_off(), and hx8347a_backlight_on().

#define CONF_HX8347A_CLOCK_SPEED   8000000UL

Select a SPI clock speed.

This selects the clock speed for the SPI clock used to communicate with the display controller. Higher clock speeds allow for higher frame rates.

Note

That the clock speed may be limited by the speed of the microcontroller a normal limitation would be CPUclk/2. For more details please refer to the device datasheet.
