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)

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?

----------------------------------------------------------------------

如果是我看錯, 請指教! 謝謝!

是否C編譯器判斷PORTD是屬於BSR=0xF
所以C編譯器在MOVLB後面放0xF

我知道
SWAPF 0xf83, F, ACCESS
這行不需要知道BSR
所以這行MOVLB 0xf 目前沒有意義


我知道他不會出現MOVLB PORTD
而是應該MOVLB 0xF83
但是為什麼出現MOVLB 0xf ?
他是根據什麼道理留下0xf ?
是取0xF83的0xF嗎 ?

這才是我的問題
求教大家

我的問題重新敘述一次
------------------------------------
在p18f4520.h裏有這段內容

#define Swapf(f,dest,access) {_asm movlb f swapf f,dest,access _endasm }

我的問題是
根據movlb f
應該是翻成MOVLB PORTD
為什麼是MOVLB 0xf ?

C語言:
Swapf(PORTD, 1, 0);

翻譯成組語為:
010F MOVLB 0xf
3A83 SWAPF 0xf83, F, ACCESS

其中MOVLB後面為什麼是 0xf ?

請教大家一下!

謝謝!

在p18f4520.h裡有以下一段內容
我想知道他的設計原理
所以有以下的疑問

extern volatile near unsigned char LATA;
extern volatile near struct {
unsigned LATA0:1;
unsigned LATA1:1;
unsigned LATA2:1;
unsigned LATA3:1;
unsigned LATA4:1;
unsigned LATA5:1;
unsigned LATA6:1;
unsigned LATA7:1;
} LATAbits;

LATA因為已經宣告extern, 而且在p18f4520.inc裏可以找到, 所以沒問題
但是LATAbits雖然也是宣告extern, 但是p18f4520.inc裏找不到, 那到底LATAbits這個名稱是如何命名的? 又如何知道LATAbits的位址? 難道是擺在一起的原因嗎?

假設程式如下
作step over 時
執行完call DELAY後應該停在下一行
例如movlw 0x00或bra loop
但是實際上卻不會停下來
而是停在call DELAY後的第2行
請問這是正常的嗎?
晶片是pic18f452
發展工具是ICD2

ORG 0x0000
goto Main
Main:
clrf TRISD
loop:
movlw 0xff
movwf PORTD
call DELAY
movlw 0x00
movwf PORTD
call DELAY
bra loop
;********************************************
DELAY:
movlw 10
movwf 0x21
del1: movlw 200
movwf 0x22
del2: movlw 200
movwf 0x23
del3: decfsz 0x23
bra del3
decfsz 0x22
bra del2
decfsz 0x21
bra del1
return
END

跟作業系統有關嗎?

我的是XP SP1

我換一台SP2電腦

已經開始有偵測到了

似乎比較正常了

MPLAB REAL ICE detected

Firmware Suite Version...... 01.14.21
Firmware type......................dsPIC33F/24F/24H
MPLAB REAL ICE Connected.

換了好幾個板子

還是偵測不到?

手動更換韌體

到這裡應該好了

可是他永遠處在下載狀況

就是不結束
