i have a project where ram has become a precious resource. i have reconfigured my code so that i should be allowing the linker to overlay as much as possible (all code on the idle loop). my problem is how do i determine how much ram is used? ie how good a job has the overlay mechanism done? i can see what the linker says is 'overlayable' but is there an easy way to determine how much ram i currently have available? thanks! robert
