Hi All!

Is it possible ( difficult I think) to create a component which can drive a VGA monitor. I think, so it is possible to use it like a GLDC screen, with fonts and able to write in X and Y posisition. It would be a very nice big display.

Sorry, I am not able to do it.

Thank´s in advance

Hello Jorgen,

The raspberry pi has full hd HDMI output which you can use as a glcd in flowcode. 4d systems used to have a vga module which was good but a bit slow. Not sure if this is still available.

Driving a vga is possible even with an 8bit pic or avr but its very timing critical so hard to make a generic component. I tried back in the days of fc 3. The resolution would be limited by the amount of ram available. Most monitors have minimum resolution so driving a high enough res and having enough ram and being able to do anything else is tricky.

Hope this helps.

Hi Ben!

Well ok, I will buy a RPI and will give it a go and try it with FC8. Thank´s.
Concerning use a Pic or Arduino I understand. Mean while, now remember Martin (Medelec) have created something with with seriel monitor, I will also look at this. Look for it

Buy the way, are you working 24/7
