I just got my EMX module.
I started working on the PCB that will host the module and some other stuff. I would like to use this LCD (LB043WQ1-TD01 - http://www.gst-lcd.com/spec/tftspec/LB043WQ1-TD01.pdf) with the EMX module because I already have it on my desk with all the other stuff needed. My question is if works with EMX?
The LCD does not have a vertical sync pin neither a horizontal sync. I think that connecting DATA ENABLE (LCD) with HSYNC (EMX) should work properly but I would really dislike building the PCB and finding out that it actually doesn’t work. So I thought I should ask the PROs first.
So, will it work?
If yes, could you give me a test sample code for my LCD configuration?
Would this config work?
Width = 480 Height = 272 HorizontalBackPorch = 20 HorizontalFrontPorch = 25 HorizontalSyncPolarity = true HorizontalSyncPulseWidth = 480 //(high for all the line pixels? - datasheet says that must hold at least 10ns but the graphs show otherwise) OutputEnableIsFixed = true OutputEnablePolarity = true PixelClockDivider = 8 //(9MHz clock)? PixelPolarity = false PriorityEnable = false //(is it needed?) VerticalBackPorch = 7 VerticalFrontPorch = 7 VerticalSyncPolarity = true VerticalSyncPulseWidth = 2
LE: I investigated further and found out that this display is a DE mode only. So, no hsync/vsync, just DE. From what I can understand, DE is the same as hsync. So it should work with the vsync not connected. Am I missing something?
