void ADC_Initial(void)
{
AD1CON1 = 0b0000000000000110 ; set SAMP auto set
AD1CON2 = 0b0000000000000000 ;
AD1CON3 = 0b1000001100001111 ; internal RC clock
as A/D clock
Auto-sample time

AD1CHS0 = 0x00 ;
AD1PCFG = 0b1111111111111011 ; AN2 enable
AD1CON1bits.ADON = 1 ; A/D module
enable
}

請問是A/D 初始化有問題嗎?
而PIC24FJ256GB110 Family datasheet(編號39897b)上AD1PCFG改成AD1PCFGL 和 AD1PCFGH但是
程式編譯會出現undefined錯誤

PIC24FJ64GB106.o(.text+0xd2): In function `ADC_Initial':
D:\Code\PIC24FJ64GB106\PIC24FJ64GB106.c:90: undefined reference to `AD1PCFGL'
Link step failed.

是這個問題讓A/D轉換不正常嗎??

小弟用 APP026-3 開發板MCU用PIC24FJGA006
run光碟Demo的範例程式 AD轉換值都正常
但是MCU我換上PIC24FJGB106後
register名稱照datasheet修改 AD1CHS改為AD1CHS0
AD的值一直維持在1023..沒有改變
請問是哪裡有問題阿??

int main(void)
{
int LoopVar1 ;

ADC_Initial() ;
PMP_Initial();
AD1PCFGbits.PCFG15 = 1 ;
LCD_Initial() ;

LED0 = 0 ;
TRISDbits.TRISD0 = 0;

putrsLCD("I am APP026-3") ;

LCD_SetCursor(0,1) ;
putrsLCD("ADC=") ;

while(1)
{

AD1CHS0 = 0x0002 ;

AD_Delay() ;
AD1CON1bits.SAMP = 0 ;

Nop() ;
Nop() ;
while ( ! AD1CON1bits.DONE ) ;

ADC_TempValue = ADC1BUF0 ;

}
