感謝大家的回覆!
的確是與電路有關,發現是燒錄時電壓需維持5V以上,我的電路是4.9V,因此一直出問題.

現已將電壓回復至5V以上,問題已解決!

PIC16F57 燒錄與起不起振無關,還是認為線有接錯或接了不該接的電阻或電容。

哎呀!我確實確認過Configure-->Select Device的型號是PIC16F57,我是透過ICD2給電,也量過電源供應是5V,
但還是出現上列訊息?

是否ICD2 progrmming 時,震盪器起振與否可以忽略?

ICD2 是可以燒錄 PIC16F57 的,看起來 ICD2無法認知 PIC16F57,有沒有給電或腳位鬧錯了。

看起來ICD2沒認到你的PIC16F57...
1.檢查Configure-->Select Device有沒有選對型號
2.電源及ICD接線腳位正不正確
3.檢查PIC16F57有沒有壞...

當我程式build成功後要將code燒進PIC16F57時,出現以現訊息

MPLAB ICD 2 Ready
Connecting to MPLAB ICD 2
...Connected
Setting Vdd source to MPLAB ICD 2
...Reading ICD Product ID
Running ICD Self Test
...Passed
MPLAB ICD 2 Ready

此訊息代表我連線正確,但是當我要燒錄程式時,出現以下訊息

Programming Target...
ICDWarn0052: MPLAB ICD 2 cannot validate a target device. Please make sure that the target device is connected and properly powered. Select "OK" to continue, or "CANCEL" to abort the operation
...Validating configuration fields

ICD0275: Programming failed.
MPLAB ICD 2 Ready

結果燒錄失敗?
尤其是一直出現ICDWarn0052的錯誤訊息...
請問哪裡可能發生問題??
