DLE, We succeeded in connecting multiple LCDs using RGB565 to the DK-S7G2 board. (also we built adapters you guys might have seen FAEs carrying around) That connector J102 doesn't have enough pins for 24bit mode. So RGB565 is ideal. (also better RAM usage and memory bandwidth) Also 7" 800x480 RGB565 doesn't look bad. But you must modify some graphics correctly to prevent color banding. Note that you are supposed to connect some pins together on J102 (like 1-2 maybe) to use the detection mechanism on the DK. Also there are some switches that must be enabled on the DK-S7G2. If powering stuff from the DK use the 5V output to your own regulators. Also make sure you have a good enough 5V input to the board. You should post up the timing section of your LCD datasheet picture, and your SSP settings for the LCD. Make sure the DE, HSYNC, VSYNC, and clock are on the correct pins using the TCON settings. You should scope these out close to the LCD to make sure you are sending them to the correct pins. You should follow the GUIX guide to get a project you know works on the 4.3", then create a new 800x480 GUIX project file set in the same way, then modify the LCD settings in your E2 project to match the new LCD. This will provide a good software starting point to make sure you don't miss anything. We used clock on pin 30, Vsync pin 28, DE pin 26, and Hsync pin 27 if that helps. Pin 40 can be PWM I believe. (not sure if we actually tested that) Also note that with this particular board, it is a good idea to stick an I2C buffer on your LCD adapter if you use a PCAP display. If you use 4WRT use the SX8656 IC to change it to I2C interface. Synergy has the driver for it. Also note that Synergy probably still has I2C timing issues in stock SSP code. So you might want to patch it to be compliant to fast-mode, or use standard mode only as the timing requirements are more relaxed. If interested we might have some of the 7" PCAP assemblies+adapters that we could sell you. Of course the easy way is to just purchase our 7" development kit with part number: SYG-S7G2-70C-MDK Then you can have your 7" Synergy touchscreen running out of the box. If you purchase an FDI Synergy kit please email us when you do which would give us time to send you some demo SW by the time your kit arrives. It looks like we haven't published much SW yet. (partially due to SSP rapidly evolving the last few months) Bill
