Color balance may be adjusted, brightness operates with Lcdcontrast command.
It has hardware drawing lines and boxes. And it makes it very quick - look at video https://youtu.be/POjIicuz4lo

Hi Mrshilov,

thank you for the code.
In my configuration the demofile works until the circle command is sent, from this point the
display does not respond anymore and needs a reset.
Text also doesn't work.
Rectangles and lines work perfect.
So as far as I understand, as long as you adress the build in Graficfunctions it works, additional commands doesn't.

I'm working with ATMEGA128, configuration is
Config Graphlcd = Color , Si = Portb.2 , Sclk = Portb.1 , A0 = Portc.6 , Cs1 = Portb.5 , Rst = PortB.4
$crystal = 14745600

Do you have an idea what is wrong?

Thank you very much again, this is the only bascom source code I found on the web for this amazing
display, and I don't want to switch to another programming language like arduino since bascom is much better.

Best,

Michael

I have buy this lcd but before I connect it I would like to know if you use 5v 3.3 shifter.
My board said that accept voltage from 3.3 to 5v but i would like to know how you guys have connected this lcd.
Also the dc pin is connected to ground?

D/C pin named as "A0" in "Config Graphlcd".
CS is optional and may be connected to GND. RES also optional and may be connected to Vdd.

Vdd for SSD1331 is from 2.4V to 3.5V (see datasheet).
