Testing and debugging real-time embedded software can be challenging. In fact, it’s surprising that more tools aren’t available to simplify embedded product design. Any tool that offers instant visibility into the inner workings of your application is worth looking into.
The forethought of chip designers in providing versatile debugging interfaces (as those found on modern processors such as the ARM Cortex-M and Renesas RX processors) makes it easier for tools to peek inside running embedded systems without interfering with the CPU. Data-visualization tools such as µC/Probe let you see inside an embedded system to effortlessly confirm the proper operation of the design, or reveal anomalies you can identify and fix, leading many to ask, “Why didn’t I think of that?”
