Free Energy Micro tool resolves MCU pin conflicts

Oslo, Norway – Energy Micro has introduced energyAware Designer, a free software tool that ensures correct pin configuration for the EFM32 Gecko low power MCU family. The new tool automatically generates set-up code and documentation.

On creating a new project, designers select a target MCU and are presented with a default device configuration. Clicking on a peripheral function enables it and highlights respective pins in green on an intuitive pin-out diagram. When pin conflicts are induced by selecting another peripheral routed to the same pins, they are highlighted in red. The software suggests an alternative peripheral location; choosing the suggested location resolves the conflict. Configuration of GPIO resources and clocks are handled in a similar way.

Once satisfied with the overall MCU configuration, designers can then use the energyAware Designer tool to generate the corresponding C-code file, which can be cut-and-pasted directly into the application code. At the same time, detailed PDF documentation can be exported, reporting the final device pin-out map in diagrammatic and a choice of tabulated formats.

Based on the ARM Cortex M3 core, Energy Micro's EFM32 Gecko microcontroller family has been proven to consume a quarter of the energy required by other 8, 16 and 32-bit microcontroller solutions. The EFM32 Gecko microcontroller is in full production and details of the software and pin-compatible Tiny Gecko and Giant Gecko products have recently been announced.
