| ============= Device CMSIS Compliant Peripheral Support Library ============== | |
| This archive contains header file and peripheral support libraries for | |
| Silicon Labs EFM32 and EZR32 series of microcontrollers and System-On-Chip | |
| devices. | |
| ================ About Device ================================================ | |
| The library and header files are based on CMSIS, the Cortex Microcontroller | |
| Software Interface Standard, as defined by ARM Ltd. | |
| For more information about the CMSIS standard in itself see | |
| http://www.onarm.com/cmsis | |
| http://www.arm.com/cmsis | |
| In short, CMSIS tries to provide a common interface for programming devices | |
| having one of the Cortex-M core architectures, making code sharing and reuse | |
| easier. | |
| ================ Development Environments ==================================== | |
| You will need a development environment which supports Silicon Labs EFM32/EZR32 | |
| devices. Currently this can be one of either | |
| Atollic TrueStudio for ARM | |
| http://www.atollic.com | |
| CooCox CoIDE | |
| http://www.coocox.com | |
| Hitex HiTop IDE | |
| http://www.hitex.com | |
| IAR Embedded Workbench for ARM | |
| http://www.iar.com | |
| Keil uVision "MDK-ARM" | |
| http://www.keil.com | |
| Mentor Graphics CodeBench (previously Codesourcery Sourcery G++) | |
| http://www.mentor.com | |
| Rowley CrossWorks for ARM | |

| The version required depends on the family of products you are developing | |
| for, check with the vendor for compliance for a particular device. | |
| It is possible to develop with other tools, but these vendors provide good, | |
| integrated development environments for Silicon Labs EFM32/EZR32 devices. | |
| This library uses C99-types, requires the presence of <stdint.h> and can use | |
| other functionality standardized in C99. If your compiler has a C99 compliance | |
| toggle, you should enable it for your projects. | |
| ================ File structure ============================================== | |
| Short getting started guide: | |
| The quickest way to start is to base your work on one of the simple example | |
| projects for the Silicon Labs EFM32/EZR32 Development or Starter Kits. These | |
| should be easy to port and change to adopt to your needs. | |
| The board support packages for the various Silicon Labs EFM32/EZR32 kits comes | |
| with a "blink" example, that serves as a good starting point for new projects. | |
| Please note that you _will_ need to change the "Debugger" and "Flash/Download" | |
| configuration settings to fit your environment. See your IDE's manual for | |
| details. You might also need to change the limits of the linker file to adopt | |
| to your part's SRAM and flash size limits. | |
| Support for Silicon Labs EFM32/EZR32 devices family is located in the directory | |
| Device/SiliconLabs/<FAMILY>, | |
| where family could be one of EFM32G, EFM32TG, EFM32GG, EFM32LG, EZR32WG or | |
| others. | |
| The most convenient way to start a project, is to define the device target | |
| in your compiler options, e.g. add a -DEFM32G890F128 to your compile options | |
| if you are targetting an EFM32G890F128 part. | |
| Include the file "em_device.h" wherever you need register and bit field | |
| definitions for the peripherals or the MCUs/RF transceivers, after setting | |
| the correct include path to point to your "family". | |
| Gecko peripheral registers follow the CMSIS convention of defining a | |
| structure which hold "volatile" peripheral registers. Again, take a look | |
| at the examples for usage. | |
