ADC配置如下，通过PA5（AD_IN5）采集电池电压，每100ms使用adc_software_trigger_enable(ADC_REGULAR_CHANNEL)触发采集一次数据，每10个数据取中值作为电池的电压有效数据。
void adc_config(void)
{
/* ADC CONTINUOUS function enable */
adc_special_function_config(ADC_CONTINUOUS_MODE,DISABLE);
/* ADC channel length config */
adc_channel_length_config(ADC_REGULAR_CHANNEL,1);
/* ADC regular channel config */
adc_regular_channel_config(1,ADC_CHANNEL_5,ADC_SAMPLETIME_55POINT5);
/* ADC external trigger enable */
adc_external_trigger_config(ADC_REGULAR_CHANNEL,ENABLE);
/* ADC external trigger source config */
adc_external_trigger_source_config(ADC_REGULAR_CHANNEL,ADC_EXTTRIG_REGULAR_NONE);
/* ADC data alignment config */
adc_data_alignment_config(ADC_DATAALIGN_RIGHT);
/* enable ADC interface */
adc_enable();
/* ADC calibration and reset calibration */
adc_calibration_enable();
}
第一条语句ADC_CONTINUOUS_MODE配置成disable时，采集到的是一个固定的值，配置成enable时采集的是0，用过的帮忙看下哪里配置错误了吗？感谢！串口读到的数据如下：
