There are two plug-ins for IAR. The first is a ‘state viewer’ plug-in provided by WITTENSTEIN high integrity systems. That gives you a snapshot of the task states, stack usage, etc… Second there is a fully thread aware plug-in that gives you the call stack, variables, etc. of each task. I don’t think either show a bar graph. Looking at the uCOS plug-in, it appears as if the bar graph is showing the same data and the numerical data in the previous column. Is that the case? If so, does it add anything?
