To avoid flickering:
Create a descendent of TCustomControl, call Invalidate and
Application.ProcessMessages, in Paint draw to a bitmap and draw the bitmap
to the canvas.
Because a paint will take longer than a 500kHz intervall, you either call
Invalidate only once a second and loose some data, or you use threads.
