I'm looking into messing around with your code, do you have the parameters for NTSC video. Also a circuit that will convert SCART interface to composite video.

Can it be modified to suit Touch Screen terminals, probably with XSRAM / Flash?

quite honestly I was disappointed, cause I was looking for a real graphics project, not one that initializes a graphic compatible display. I was looking for generic routines to draw lines circles boxes, bitmaps, maybe even 3D
AND I was looking for efective ways to move data to the display, i.e. to record it online and transfer at constant times, or always writing to the display at once; handle display region updates; so short to speak all the wild stuff, that is IMHO quite complicated.

Since I am on a EL type display the toshiba chip hasn't much value for me :(

Hi SCALAR,

 

I am fully aware that this topic is very very old but it has awakened my interest because I am now in a design that should use a GLCD 240x128.
I have studied your proposal AVR Graphics Project and think it's excellent, well structured and commented, but I got several compilation errors with the headers, what could be predictable after so long time.

 

Please indicate if you have any updates of your S/W and from where to download, or if you can suggest me where to look for other libraries.

I use Atmel Studio 7, I have reserved the PORTA for ADC and at the moment I simulate Proteus.

 

Thanks.

Trizas.

Note that SCALAR hasn't made a single post here in nearly ten years.  I highly doubt your request will be heard.

Thanks joeymorin. It was just in case,....  but I really need to progress with my project.

Regards,

Trizas.

Go on: in the >10 years since, GLCD have become commonplace, even for AVR-class processors - just stick "AVR GLCD Library" into your favourite search engine ...

 

Or just look at Arduino projects ...

Top Tips:

  1. How to properly post source code - see: https://www.avrfreaks.net/comment... - also how to properly include images/pictures
  2. "Garbage" characters on a serial terminal are (almost?) invariably due to wrong baud rate - see: https://learn.sparkfun.com/tutorials/serial-communication
  3. Wrong baud rate is usually due to not running at the speed you thought; check by blinking a LED to see if you get the speed you expected
