hello,
I discover the Display3000, it nice but I have a problem, the line is difficult to draw, I have a solution but it is a little bit heavy: draw dot by dot.

I explain to draw a line the X1, Y1 coordinate must be in the upper left corner, and the X2, Y2 in the lower right corner.

My problem is to make an analogic clock so I need to have the center of circle X1, Y1 and I dont find the method to draw the line for 7 hours for example

Bascom 9.0, atmega128
Many thanks

JP

In fact all lines are drawn dot-by-dot, you just need a good way of figuring out where the dots go. Lookup "Bresenham algorithm" on the net. This is the standard line drawing technique.

Hi JP,

I using a D072 2.1" display since monday. Itīs great!
Why donīt you use the commands from display3000?
Include a few .bas files from display3000 into your prog, and draw a line:

call ldc_draw (x1,y1, x2,y2, [thickness], [color])

Read the display3000 software-manual!
