Hi, here is a blog post on using counters on the Mimas V2. The code will also work for the Elbert V2 board but the Clock speed and UCF file would need to be changed to account for the different boards. http://langster1980.blogspot.co.uk/2016/04/a-simple-post-on-counters-for-mimas-v2.html Hope it is of some use to people. Cheers Alex
