Each pulse burst is 562.5µs in length, at a carrier frequency of 38kHz (26.3µs). Logical bits are transmitted as follows (Fig2): Logical ‘0’ – a 562.5µs pulse burst followed by a 562.5µs space, with a total transmit time of 1.125ms

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. Webir-code-finder-nec-protocol-7. App Name. is the most famous version in the series of publisher.
