PSoC1 DTMF User Module
I seem to be unable to build a project using the example code in the DTMF Dialer datasheet V1.5. Even after substituting #include "DTMFDialer.inc", with #include "PSoCAPI.h", I still get warnings and errors about using functions without a prototype. Any suggestions would be appreciated.
