| /* IRLibHardware.cpp | |
| * Part of IRLib Library for Arduino receiving, decoding, and sending | |
| * infrared signals. See COPYRIGHT.txt and LICENSE.txt for more information. | |
| * | |
| * We need a way for the sending object to communicate with the receiving object. | |
| * Sending an IR signal can disable further receiving because the timer needed for the 50us | |
| * interrupts is used to modulate the frequency of the PWM output signal. We need a flag | |
| * for the send object to inform you receive object that this occurred. | |
| * | |
| * Some applications do sending only and would only require you to include IRLibSendBase.h | |
| * while others only do receiving/decoding and would include IRLibRecvBase.h but not | |
| * IRLibSendBase.h. The only include file that is used by both sending and receiving is | |
| * the IRLibHardware.h which was formerly called IRLibTimer.h. Therefore we put the flag | |
| * in this newly created IRLibHardware.cpp module. That way a send only can put the flag | |
| * here whether or not there is a receiver. Similarly the receiver can check the flag | |
| * whether or not there is a sender. | |
| * | |
| * The below is a global flag IRLib_didIROut that gets set true with every call to enableIROut. | |
| * Then any call to IRrecv::enableIRIn checks this to see if it needs to restart the ISR. | |
| * Regardless IRrecv::enableIRIn will always reset it it false for the next time. | |
| * Note as always if you try to send while in the middle of receiving, the partially received | |
| * data is lost. If the application wishes to create a system where the sending waits until | |
| * the receiver is idle, the programmer can implement such a system themselves and deal with | |
| * the consequences. | |
| * | |
| * The bottom line is the application no longer needs to figure out if it needs to | |
| * call enableIRIn or the "resume" method. There is no more "resume". You always do | |
| * enableIRIn after every decode and the system handles it. | |
