TFT to VGA or USB Display convertor


#1

Is there any way to connect the G120 etc to these displays


#2

Why but user vga? It will be lower cost


#3

Even if you wrote a driver for it it would be very slow. You are much better using the native RGB peripheral on the G120 if you can.


#4

using VGA or something like that.
Then you are free to buy a standard monitor or touch monitor. So cut down on the cabinet cost.


#5

Something like this? https://www.ghielectronics.com/catalog/product/356

I’m not sure how similar the touchscreen USB output is to a standard mouse though.


#6

That module is expensive.
I am thinking a bit different

There is VSYNC and H SYSNC
and the RGB signal.
You can make a R-2R resistor DAC or use a DAC chip for each color.

if GHI can help changing the SYNC to be usable for a monitor.

Then this can be done cheep.


#7

We did this already a long time ago. You get 480x480 pixels. It loads the processor much to keep up with the update rate.

About the vga module, how many do you need?
