Maple rev 5, Maple IDE 0.0.12</p> <p>The C++ library (SoftSerial.h. SoftSerial.cpp) was put into a folder under %mapleIDE%/libraries. Tried to add a timer interrupt to that.<br /> Declared<br /> HardwareTimer timer(2);<br /> in the MapleIDE sketch after || before<br /> #include "SoftSerial.h"</p> <p>I was not able to<br /> a) have the compiler recognize a public field of type HardwareTimer in the SoftSerial class defined in the header of the library (Compiler error: Type unknown)<br /> b) have the compiler recognize a global instance of type HardwareTimer in the SoftSerial library<br /> c) tried out all possible includes in the library, from FreeRTOS.h to timers.h</p> <p>Workaround:<br /> had to move all the functions in the former library class to a sketch *.pde file,<br /> rename all LCD.%functions% to LCDfunction in the main sketch - dropping object oriented concepts in order to make things working.</p> <p>Noticed, that a class constructor function having parameters is not accepted by the compiler, when it is not stuck in a library, but in the main sketch.<br /> The library however cannot access to the class type declaration of HardwareTimer.</p> <p>Any ideas what went wrong? (Code too large to be posted here...) </p>
