5.2 Graphics Connectors or GFX Card Interface
The SAM E70 Xplained Ultra Development Kit is designed to have a modular graphics interface. This
interface enables using several graphics cards, which allow for expandability and different use cases. A
565 adapter card is included in the kit, which takes 16-bit parallel LCD data and converts it to 24-bit data.
This card also provides access to ADC for resistive touch screens, hence an external controller is not
needed. See table below for pin descriptions.
