Feedback LED can be activated for sending / receiving.Any pin can be used for sending -if SEND_PWM_BY_TIMER is not defined- and receiving.The parameter bool hasStopBit is not longer required and removed e.g.You must replace #define DECODE_DISTANCE by #define DECODE_DISTANCE_WIDTH (only if you explicitly enabled this decoder).Improved handling of PULSE_DISTANCE + PULSE_WIDTH protocols.Ĭonverting your 3.x program to the 4.x version.Callback after receiving a command - It calls your code as soon as a message was received.RawData type is now 64 bit for 32 bit platforms and therefore codedRawData can contain complete frame information for more protocols than with 32 bit as before.Printout of code how to send received command by IrReceiver.printIRSendUsage(&Serial).New universal Pulse Distance / Pulse Width decoder added, which covers many previous unknown protocols.Allows receiving and sending of raw timing data.# define DECODE_NEC //#define DECODE_DENON Protocols can be switched off and on by defining macros before the line #include like here: Universal Pulse Distance Universal Pulse Width Hash ProntoīoseWave Bang & Olufsen Lego FAST Whynter MagiQuest NEC / Onkyo / Apple Denon / Sharp Panasonic / Kaseikyo Quick comparison of 5 Arduino IR receiving libraries.Why do we use 30% duty cycle for sending.Hardware-PWM signal generation for sending.Incompatibilities to other libraries and Arduino commands like tone() and analogWrite().
