WebMar 25, 2015 · The IR transmitter SendNEC () transmits a code in NEC format. It uses Timer/Counter1 in Fast PWM mode to generate the 38kHz carrier, by setting a prescaler of 1 and a TOP value of 209, and the output to OCR1 is inverted. To generate a half-bit gap it sets OCR1A to TOP, which generates a continuous low output on OCR1. Web• A final 562.5µs pulse burst to signify the end of message transmission.
