→Physical interfacing
This application note describes the interfacing of Ampire AM-800480STMQW-TA1 display to BoraEVB. This project is based on [[Bora_Embedded_Linux_Kit_%28BELK%29#BELK_software_components|BELK 2.2.0]].
==Physical interfacing==
To interface the display a small adapter board is needed. It interfaces J22 connector on BoraEVB side and provides a 20-pin connector to directly attach display cable. It The adapter board * is also equipped with a linear regulator generating 2.5V. This voltage is used as power supply for the VDDIO_BANK13 rail. This voltage is required to implement LVDS differential pairs that drive display.* integrates a pad (denoted as TP1) that is used to connect 5V power supply generated by MOD2 PSU of BoraEVB. This additional power rails is required by display backlight circuitry.
At this URL TBD schematics are available for download.
==Block diagram and Vivado design==
The following picture shows simplified block diagram of the design.
