This is great for optimization but causes issues where a fixed size is expected. We worked around this issue by setting an element to 65535. But it is not clean. Is there a way to force enums to UInt16 in KDS?</P></BODY></HTML> Thu, 09 Apr 2015 15:50:47 GMT https://community.nxp.com/t5/Kinetis-Design-Studio/set-enumeration-size/m-p/394176#M2472 barbercolman 2015-04-09T15:50:47Z Re: set enumeration size https://community.nxp.com/t5/Kinetis-Design-Studio/set-enumeration-size/m-p/394177#M2473 <HTML><HEAD></HEAD><BODY><P>Hi Dale,</P><P>this is actually not a question about KDS, this is a question about compilers (well, gcc).</P><P>There is a good article about this topic:</P><P><A href="http://stackoverflow.com/questions/1113855/is-the-sizeofenum-sizeofint-always" title="http://stackoverflow.com/questions/1113855/is-the-sizeofenum-sizeofint-always">http://stackoverflow.com/questions/1113855/is-the-sizeofenum-sizeofint-always</A></P><P>and you will find more if you search the internet e.g. for</P><P></P><P>gnu gcc force enum size</P><P></P><P>Some compilers have options to set the size.
