Examples

Receive Data

Example to receive data via RC5 encoded IR. RC5 incoming data pin connected to pin RB0. If a valid RC5 packet is received then the 8-bit data is shown on the PORTD pins and the 5-bit address data is shown on the PORTA pins. RC5 Receive Example

Transmit Data

Example to send data via RC5 encoded IR. The transmission is done via the RC0 pin and the modulation is performed by the PWM output signal on the RC2 pin. The data and address values are incremented after each transmission. RC5 Transmit Example

Schematic showing the required hardware to combine TX masking pin and PWM output pin.
