we are trying to interface some cheap LCD panel to the BBB after checking some OpenSource designs we noted that all of them dont connect the data and control line from the beagle directly to the LCD . some designs are adding serial resistors on each line like this one , page #7 http://www.4dsystems.com.au/new/productpages/4DCAPE-43/downloads/4DCAPE-43(T)_datasheet_R_1_4.pdf
or even more adding a transceiver IC that is not inverting or level-shifting the signals like the LCD capes made by circuitco , page #21 http://www.openhacks.com/uploadsproductos/beaglebone-lcd7-reva2-srm.pdf so please , can any one explain those designs to me and how to calculate those resistors if they depend on some panel parameters i have already modefied a DTO and loaded it and successfully fried a LCD panel that was directly interfaced to the beaglebonebBack thanks in advance -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
