dac输出正弦波形的电压,是怎么算出来的?
const uint16_t sine[] = {2047, 2251, 2453, 2651, 2844, 3028, 3202, 3365, 3515, 3650, 3769, 3871, 3954,
4019, 4064, 4088, 4095, 4076, 4040, 3984, 3908, 3813, 3701, 3573, 3429, 3272,
3102, 2921, 2732, 2536, 2335, 2132, 1927, 1724, 1523, 1328, 1141, 962, 794,
639, 497, 371, 262, 171, 99, 45, 12, 0, 7, 35, 84, 151,
238, 343, 465, 602, 754, 919, 1095, 1281, 1475, 1674, 1876
