实验目的:通过学习此程序可以了解DSP的SPI与DA芯片(TLV5620)的连接和驱动，这是DSP的一个重要特性,大家要达到掌握的程度实验说明:主要硬件由DSP和TLV5620组成,DSP提供了SIMO和SCLK、C3TRIP **
** 信号给TLV5620，且C3TRIP信号是用来做片DAC信号的更新和锁 **
** 存的，这里大家要参照我们所提供的TLV5620的手册，4个信道 **
** 的DAC输出分别引了出来，方便大家来检测.这里还要说明的一点的是我们用了其中的两个信道DACA和DACB作为ADC的输入，大家看电路便知。 实验结果:用万用表测试TLV5620的4个输出电压值，可看到他们是成比例关系，分别0.4V,0.8V,1.2V,1.6V. 实际测量值有些误差的-** Purpose: To study this program can understand DSP s SPI and DA chip (TLV5620) connection**** and drive, which is an important feature of DSP, we have to achieve master degree**** experiments show: The main hardware and TLV5620 composed by the DSP, DSP provides SIMO and SCLK, C3TRIP**** signal to TLV5620, and C3TRIP signal is used to do the update and locking plates DAC signal**** store, where we have to refer to our TLV5620 manual provided by the four channels of DAC output** respectively lead out, to facilitate testing. Here also described a** point it is that we used one of the two channels DACA and DACB as ADC inputs,** we see circuit at a glance.** Results: with four output voltage values multimeter test TLV5620 can see that they are proportional relationship**, respectively 0.4V, 0.8V, 1.2V, 1.6V and some actual measurement error.
