I am trying to port the Nextion arduino libs and they are calling utoa like so
utoa(number, buf, 10);
I have been doing some research and it appears that utoa is from stdlib.h for arduino but utoa is non-ISO C function. How/where should I define this function? I have application.h included but I am guessing that because it is non-standard it wasn’t included in application.h. Thanks.
stdlib.h reference doc
