No and I did not read the manual for the smaller cortex-m* cores either even though I use them daily. > I've been using many of those small ARM cores (M0...M4) from different > manufacturers and each is about a 1000 pages.

In no doubt there are plenty of infra structure and if the infrastructure is needed there are not much choice. I think there is need for only one task and have been looking on some of the smaller micro controllers. ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
