哪位大侠个谁用过PIC12F675芯片，给我个程序范例最好是ADC的，谢谢了，我现在做个项目，用的是PIC12F675芯片，以前没用过这个芯片，感觉有点吃力，哪位大侠给个范例程序即可。

unsigned int ReadADC(unsigned char channel){
    unsigned int value;

   //read the ADCH will permet updata
ADCON0 = 0x81; //Right justified,and enable the ADC
    ADCON1 = 0x50; //set the ADC clock to 1/8 FOSC
ADCON0|= (channel<<2);    //Switch to the select adc channel
