TLC5620 DAC转换实验程序 该实验程序使用TLC5620中A、B、C、D四个通道中的前两个通道分别输出周期相等、幅度均为3.3V的三角波和方波，5620的输出经过LM358双运方的反相跟随后增强了带负载能力 并且使得输出的信号电压位于-3.3V～0V之间，起到了模拟反相的作用。在程序中，RNG位的置位使得输出幅度增加一倍。-TLC5620 DAC conversion of the experimental procedure experimental procedure TLC

有一个首地址为MEM的100个字的数组，删除其中的所有为0的项，并将后续项向前压缩，最后将数组的剩余部分补上0-A first address of the array of MEM of 100 words, delete all for 0, and follow-up forward compression, and finally fill the remaining part of the array 0
