AN-BELK-005: Interfacing BoraEVB to TFT LCD displayEdit
IntroductionEdit
This application note describes the interfacing of Ampire AM-800480STMQW-TA1 display to BoraEVB. This project is based on BELK 2.2.0.
Physical interfacingEdit
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 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.
At this URL TBD schematics are available for download.
