Examples are to use GCC with the Makefiles we provide, which can also be used together with <a href="https://devzone.nordicsemi.com/tutorials/7">Eclipse</a>, or <a href="https://devzone.nordicsemi.com/blogs/1032/segger-embedded-studio-a-cross-platform-ide/">Segger Embedded Studio</a>.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/84896?ContentTypeID=1Wed, 26 Apr 2017 14:50:17 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2fd65831-2281-4cb1-8b39-75ad5c72c75dLiverpool007<p>If i use float in that function i get error code size to big for linker while compiling.
