ADC转换电压输出不稳，导致电压显示LED灯在某个电压点闪烁。

问题补充 :

while(1)

{

if (time_10ms)

{ADCCON1|=0X30; /* clock divider */

ADCCON2|=0X0E; /* AQT time */

AUXR1|=SET_BIT4; /* ADC clock low speed */

clr_ADCCON0_ADCF;

set_ADCCON0_ADCS;

LowBat_V = (ADCRH<<4)+(ADCRL&0x0F);

if (LowBat_V>=1280+40) //1320=3.5V 43.33=0.1V 1025/1280

{

//Led_Mode=1;

//P10=0;

P11=1;

}

else if (1140<LowBat_V<1280) //1320=3.5V 43.33=0.1V

{

//Led_Mode=3;

//P10=1;

P11=0;

}
