请教MSP430进行AD采集各项配置怎么设置最好?
DCOCTL = CALDCO_1MHZ;P1SEL |= BIT3;
ADC10CTL1 = INCH_3;
ADC10CTL1 |= ADC10SSEL_3;
ADC10CTL1 |= ADC10DIV_1;
ADC10AE0 |= BIT3;
ADC10CTL0 = SREF_1 + ADC10SHT_3 + REFON + ADC10ON + REF2_5V;试验分别更改CALDCO_1MHZ、ADC10SSEL_3、ADC10DIV_1、ADC10SHT_3 为其他设置都会使ADC10MEM跳变到另一个范围,现在代码中的设置是测试下来最接近的,但还是有比较大的误差,请教这几项该如何设置达到最佳精度?
