摘要
设计了低频信号发生器,通过按键输入或PC机串口命令输入控制信号类型、频率、幅值,采用TLC5615输出相应的波形,以240*128图形点阵液晶显示。采用C语言编程,可实现正弦波,三角波,锯齿波和方波四种波形的产生,波形无失真,频率准确。
Making a design of low frequency signal generator, control signal type, in which frequency and am- plitude is input through keyboard or PC serial command, TLC5615 is adopted to output the corresponding waveform, which is displayed through 240 ＊ 128 graphic dot matrix liquid crystal. By using program language C, it can generate four waveforms such as the sine wave, triangle wave, saw tooth wave and square wave and the waveform is distortionless and the frequency is precise.
