The Microchip MPLAB development environment contains an RTOS viewer. AVIX-RT provides a plugin for this RTOS viewer allowing detailed insight in the status of an AVIX based application. Using this plugin, when the application halts on a breakpoint, the current status of all applicable kernel objects like threads and mutexes are shown. The RTOS viewer works both with the MPLAB simulator and on real silicon using Real-ICE or ICD3. The AVIX RTOS viewer plugin is available on the AVIX-RT download area and comes with a detailed user manual which is installed together with the plugin.
