Application Report SWPA225 – November 2012 1 Demy stify DSI I/F Erwan Petillon HW Systems Solutions ABSTRACT The purpose of this Application Note (APN) is to demystify the DSI I/F by presenting different configuration and their impact on the DSI protocol. The document is illustrated by numerous waveforms probe on an OMAP platform. This APN covers the DSI protocol in video mode (Non-frame buffer display) and in command mode (frame buffer display). A section dedicated to debugging tips is enumerating different method to measure various parameters and decode LP and HS packets. However the APN does not contain programming model and complete DSI protocol standard, for more details on programming model refer to the OMAP Technical Reference Manual and the MIPI DSI protocol standard.
