如上為原始檔
我已經測試過
發現錯誤
所以才上來請教
Microchip公司會發生這種錯誤嗎?

參照：

LSB 4 bit 是沒錯 , 至於 4 , 5 bit ( VCFG0 & VCFG1 ) 可能還須要與其他參數 作運算 ( 例 : .AND. ) 才會得到正確參數 ...

要追蹤整個 HEAD 檔 LOADING 太重 , 我想較簡單的方式是寫個小程式來驗證結果是否正確 應該是比較可行的方法

我是用PIC18F4520
MPLAB-C18-Std-Eval-v3_33
ADC.h內的OpenADC ()


以下參數有誤
#elif defined (ADC_V2) || defined (ADC_V5) || defined (ADC_V6) || defined (ADC_V12)

#ifndef USE_OR_MASKS

#define ADC_14ANA 0b11110001 // analog: AN0->13 and remaining channels are digital
#define ADC_15ANA 0b11110000 // All channels are analog
#endif

例如: #define ADC_1ANA 0b11111110 應該是0b00001110

#define ADC_VREFMINUS_VSS ADC_REF_VREFPLUS_VSS // VREF- = AVSS
#define ADC_VREFMINUS_EXT ADC_REF_VREFPLUS_VREFMINUS // VREF- = external


其中ADC_VREFPLUS_EXT和ADC_VREFMINUS_EXT的定義一樣?
