Nothing to do with me, I just found it on a thread:
http://www.vems.dk/cart/VEMS%20Round.pdf
Vems Round documentation is missleading, but not unhelpful.
For future refference ---> Current 0.4.0 firmware for 'Round' display only is labled as round_2009-10-12.zip and found here ----> http://www.vems.hu/download/round/AIMdisplay/round_2009-10-12.zip Jumbled in amongst all the other 1.4.x 'Round' firmwares just to make more confusing. With the Wiki page called Afresh Tiny and found here ---> http://www.vems.hu/wiki/index.php?page=AfreshTiny
See also these threads for setting up data points (note: for refference only)
