    • An IR signaling generator and method divides the functionality of generation between software and hardware to provide a flexible way to generate IR signals, such as remote control signals. The hardware includes a clock generator for generating a carrier clock signal and a data clock signal, a buffer memory that is loaded with instructions representing an encoded data sequence; a control circuit, and a transmitter including a modulator. Each instruction contains an on/off value that is to be modulated with the data clock signal and a pulse duration value that indicates how long the on/off value is to modulate the clock signal. Using the data clock signal, the control circuit measures the amount of time the on/off value modulates the clock signal and causes the buffer to advance to the next instruction in the sequence when the measured amount of time is equal to the pulse duration value.
    • IR信号发生器和方法将软件和硬件之间的生成功能分开,以提供灵活的方式来产生诸如遥控信号之类的IR信号。 硬件包括用于产生载波时钟信号和数据时钟信号的时钟发生器,加载了表示编码数据序列的指令的缓冲存储器; 控制电路和包括调制器的发射器。 每个指令包含要用数据时钟信号调制的开/关值和指示开/关值调制时钟信号多长的脉冲持续时间值。 使用数据时钟信号,当测量的时间量等于脉冲持续时间值时,控制电路测量开/关值调制时钟信号的时间量,并使缓冲器在序列中前进到下一个指令。
