From the developer:
µC/Probe is one of the most useful and certainly coolest tools you'll find in embedded systems design. µC/Probe puts you in the driver's seat, allowing you to take charge of virtually any variable, memory location, and I/O port in your embedded product. The best part? Do it while your system is running--there's no need to stop.
For the first time, "see" what's going on, such as real data being gathered in a non-invasive manner.
You may want to check out more software, such as uC-Probe or uCProbe, which might be similar to Micriµm µC/Probe.
