基于单片机的DDS信号源设计： 设计一台函数信号发生器，使其能产生正弦波、三角波、方波信号。 1、函数信号发生能产生正弦波、三角波、方波三种周期性波形。 2、输出频率在100hz到6khz 3、可实时显示输出信号的类型、频率 4、输出信号波形无明显失真 (Microcontroller-based DDS signal source design: design a function signal generator, so that it can produce sine wave, triangle wave, square wave signal. 1, the function signal generator can produce sine wave, triangle wave, square wave three kinds of periodic waveforms. 2, the output frequency at 100hz to 6khz 3, real-time display of the output signal type, frequency 4, the output signal waveform without significant distortion)

网上一些关于SCA100t的例程不少，可大多都是用内部的SPI控制，用到模拟X-Y轴引脚输出的还是太少，本程序为利用sca100t的经xout yout脚经TLC2543模拟读出实现倾角的更加精确的读数，本程序已经调试可用。(Online a lot about SCA100t routines can be used mostly within the SPI control, use the analog output XY axis pin or too little, for the use of this procedure by xout yout feet sca100t the TLC2543 analog read out by the inclination to achieve more accurate readings, the program has debugging available.)
