Ausführliche Beschreibung

ILI9341 Display Controller Component Driver aus dem ASF 3.26.0.

Definiert in Datei ili9341.h.

Makro-Dokumentation

#define CONF_ILI9341_CLOCK_SPEED 8000000UL

Select the correct hardware interface.

Currently supported interfaces are the SPI interface and the USART Master SPI interface. Select 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.

Zu beachten: 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.

Definiert in Zeile 74 der Datei ili9341.h.

#define CONF_ILI9341_RESET_PIN QVGA_LCD_RESET

Define what MCU pin the ILI9341 back light pin is connected to.

Define what MCU pin the ILI9341 reset is connected to

Definiert in Zeile 86 der Datei ili9341.h.
