Design News and Digi-Key have an online course covering programmable logic. This is the link: http://www.designnews.com/lecture-calendar.asp?cid=da.mg2.dn.aud.cecDailNL011215#lecture_track_cgid_272 I am posting this because I was asked by a couple of members to let them know when such free courses are available. If the group does not wish to know of such courses, I'll stop making such posts. Cheers, Gene Kern
