Drawing by getting coordinates from a text file

#1

Hi,

Has anyone tried to draw from a text file ? with format eg 100,150,pendown (x,y,pen position) ?

Im trying to make an arduino code that does this and im not very lucky.

Thanks for any reactions

I’ve been converting XY coordinates from and Excel sheet into a single SVG polyline. You can convert XY to SVG from a useful website liutaiomottola.com. Use firefox. I’ve converted up to 20000 XY polyline points, opened the svg file in mDraw, and plotted with the XY Plotter this way. No pen-up pen-down though. I’d also be interested in an ardiuno code that does exactly what you describe though…

hope this helps a bit…
