| bogdanm | 0:9b334a45a8ff | 1 | ================ Silicon Labs Peripheral Library ============================ |
| bogdanm | 0:9b334a45a8ff | 2 | |
| bogdanm | 0:9b334a45a8ff | 3 | This directory, "emlib", contains the Silicon Labs Peripheral Support |
| bogdanm | 0:9b334a45a8ff | 4 | library for the EFM32 series of microcontrollers and EFR4 series for RF |
| bogdanm | 0:9b334a45a8ff | 5 | transceivers and System-On-Chip devices. |
| bogdanm | 0:9b334a45a8ff | 6 | |
| bogdanm | 0:9b334a45a8ff | 7 | The "emlib" SW is designed to support all Silicon Labs EFM and EFR devices, |
| bogdanm | 0:9b334a45a8ff | 8 | from Gecko revision B and forward. |
| bogdanm | 0:9b334a45a8ff | 9 | |
| bogdanm | 0:9b334a45a8ff | 10 | Some design guidelines for this library: |
| bogdanm | 0:9b334a45a8ff | 11 | |
| bogdanm | 0:9b334a45a8ff | 12 | * Follow the guidelines established by ARM's and Silicon Labs's adaptation |
| bogdanm | 0:9b334a45a8ff | 13 | of the CMSIS (see below) standard. |
| bogdanm | 0:9b334a45a8ff | 14 | |
| bogdanm | 0:9b334a45a8ff | 15 | * Be usable as a starting point for developing richer, more target specific |
| bogdanm | 0:9b334a45a8ff | 16 | functionality (i.e. copy and modify further). |
| bogdanm | 0:9b334a45a8ff | 17 | |
| bogdanm | 0:9b334a45a8ff | 18 | * Ability to be used as a standalone software component, to be used by other |
| bogdanm | 0:9b334a45a8ff | 19 | drivers, that should cover "the most common cases". |
| bogdanm | 0:9b334a45a8ff | 20 | |
| bogdanm | 0:9b334a45a8ff | 21 | * Readability of the code and usability preferred before optimization for speed |
| bogdanm | 0:9b334a45a8ff | 22 | and size or covering a particular "narrow" purpose. |
| bogdanm | 0:9b334a45a8ff | 23 | |
| bogdanm | 0:9b334a45a8ff | 24 | * As little "cross-dependency" between modules as possible, to enable users to |
| bogdanm | 0:9b334a45a8ff | 25 | pick and choose what they want. |

| bogdanm | 0:9b334a45a8ff | 27 | ================ About CMSIS ================================================ |
| bogdanm | 0:9b334a45a8ff | 28 | |
| bogdanm | 0:9b334a45a8ff | 29 | These APIs are based on EFM32_CMSIS "Device" header file structure. |
| bogdanm | 0:9b334a45a8ff | 30 | |
| bogdanm | 0:9b334a45a8ff | 31 | As a result of this, the library requires basic C99-support. You might have |
| bogdanm | 0:9b334a45a8ff | 32 | to enable C99 support in your compiler. Comments are in doxygen compatible |
| bogdanm | 0:9b334a45a8ff | 33 | format. |
| bogdanm | 0:9b334a45a8ff | 34 | |
| bogdanm | 0:9b334a45a8ff | 35 | The EFM32_CMSIS library contains all peripheral module registers and bit field |
| bogdanm | 0:9b334a45a8ff | 36 | descriptors. |
| bogdanm | 0:9b334a45a8ff | 37 | |
