Title: MST703 LCD driver board, VGA input / firmware
Post by: kyndal on November 06, 2019, 09:27:40 pm

Hi Guys,

i have a 7" LCD with a board using the MST703-LF     (Datasheet posted elsewhere.  but i'm attaching here for the next guy)

the MST703 allows for VGA input, but on my board is not populated.  and I'm hoping to get that working

i haves seen a couple of similar but not quite layouts for other chips.  or low res pictures where i just cant quite make it out.
handful of 75ohm resistors,  capacitors etc  but not exact

do any of you guys have the same / similar board.  that could post high resolution picture / capacitor / resistor values
have a schematic for the MST703 VGA input ?   


I'm also not sure if a different firmware is required to enable this, or if its automatic ?   can be set over i2c??   

Rune

Hello, I've been working on both MST703 and the RTD2660 but have you done any progress, is your project still under going ?
