+This is the procedure to use DSP librairies on a Cortex M4 core, it should be more detailed and explain to allow others to understand the procedure and adapt it to their needs

+- In the "Linker settings" tab, in "Librairies" sub-tab, click on add and add "arm_cortexM4lf_math", click a second time on add to add "m" \\
+- In the search directories tab, in the includes sub-tab, add C:\CMSIS\PATH\CMSIS_X-X.X.X\Device\ARM\ARMCM4\Include and add C:\CMSIS\PATH\CMSIS_X-X.X.X\CMSIS\DSP\Include \\
+- In the search directories tab, in the Linker sub-tab, add C:\CMSIS\PATH\CMSIS_X-X.X.X\CMSIS\Lib\GCC \\
+- In your project, you can now add the following includes : \\
+<code c>
+#include "ARMCM4_FP.h"
+#include "arm_math.h"
+#include "arm_const_structs.h"
+#include "arm_common_tables.h"
