看你的錯誤我相信你一定是初學著，所以建議你到右邊的教育訓練裡的講義有 W100 workshop 教材先讀看看順便將裡面的練習用軟件仿真(MPALB SIM)試跑看看。

謝謝了！
我找到了些資料。不過在編譯用組語言的程式時，出現如下錯誤，什麽原因啊？"16c54c.inc" not found是什麽意思？

請問一下~~~
我用18F452要拿來試I2C Slave Mode~~~
(Master Mode已經OK了)
請問有沒有人知道哪裡有範例可以參考???
或是可以告知Initial要如何試定???
謝謝~~~

請問一下喔...在PIC16F684中PAGE的虛指令有何用處!!!!!

各位大俠好
在CCS中

為什麼常常用到printf 及fprintf
看不懂HELP中的解釋
到底用途在哪裡?

想要請教各位先進，FLASH ROM 有"讀取"次數的限定嗎(壽命減少)。
PS:是讀取不是寫入喔..

網站掛掉。現已恢復。

大家週末休息兩天也好！

如果common直接全部共地,顯不顯示直接由7-Segment 來控制,意即說沒輸出時全不顯示,是不是只要七支i/o pin就夠了,common是否可以不接電晶體或甚至直接接地即可?會影響什麼嗎?

如題

原來如此 ^_^

謝謝taiwanuser 和版主的指點，謝謝！
