The mbed community has had a pretty busy week, with first the announcement that mbed SDK would become open source, the release of mbed 2.0, and finally support for the low cost Freescale Freedom board FRDM-KL25Zpowered by Kinetis Cortex M0+ KL25Z MCU. mbed becomes open source The mbed Software Development Kit (SDK), a C/C++ MCU software platform, has always been free (as in free beer) for both commercial and noncommercial use, and the large community around mbed has written tons of code for ARM microcontrollers. But now that the SDK has now a stable API, and the developers achieved transparent portability for code based on the SDK across multiple controllers and multiple toolchains, they decided to release the SDK source under an Apache 2.0 license. Although sharing modifications is encouraged, this license allows users to keep the changes closed if they wish to do so. mbed developers explain that the 3 […]
