Supporting the EFM32 Gecko MCU family, Energy Micro’s free software tool, energyAware Designer, eliminates the problem of debugging I/O pin conflicts. Users select a target MCU and receive a default device configuration. Clicking on a peripheral function enables it and highlights respective pins in green on an intuitive pin-out diagram. Pin-conflicts induced by selecting another peripheral, which by default is routed to the same pins, are highlighted in red. The application then resolves these by choosing an alternative peripheral location, automatically suggested by the software. Energy Micro AS, Inverness, IL. (847) 345-7691.
