我想從我的傳感器的數據讀取從串口,我可以讀取端口的名稱,但我無法從它們接收數據...我在#C和串口編碼新的,以前〜無法從串口讀取數據(在C#中)
感謝和這裏是我的嘗試:

調試。調試。調試。 – 2014-12-06 06:20:02
您是否能夠通過串口獲取數據,而不是通過C#應用程序?從一個串口開始,確保你能夠從一個接收數據,讀取的結果是0,你沒有把我的變種.. – ilansch 2014-12-06 07:13:55
@ilansch我敢肯定,數據可以被其他應用程序接收,如arduino客戶。此外,我不認爲這是陣列的事情導致問題 – tristan 2014-12-06 08:44:22
