閉公司有一款產量較低的PCB,採用PIC16F883 MCU。已經有20幾年了,最近發現在MPLAB V8.92,中無法燒入(使用PICKIT3),顯示訊息,讀出的Device Code是0x2020,而正確應是0x0000。改用PICKIT3的Utility去燒錄,也有一樣的問題,但是;如果用LEAP的燒錄器是可以正確燒錄。我們當時就改用了PIC16F886,就沒有問題了。
上星期我們從Microchip DIRECT上買了15PCS的PIC16F883來做測試,使用MPLAB V8.92+PICKIT3一樣有上述的錯誤,但使用LEAP的燒錄器,卻有3顆是可以正確燒入,放到目標板上是可以正確執行,其他12PCS和上述是一樣錯誤的情形,我想問一下,有人有過這樣的經驗或是該向Microchip的哪一個部門反應?
