你在接收中斷程式裡呼叫 LCD 顯示副程式會不會造成Over Run 的問題?

謝謝大大的回覆~~~小弟是從LCM測試無誤接下來再作配合SIM100C，由PIC傳給SIM100C模組的部份功能正常，可以撥出PIC設定的號碼~~但是接收的部分就出現亂碼，也就是因為卡在傳送的地方沒問題但接收卻都不如預期而不知該怎麼辦！不知道是程式問題還是？？？希望各位大大能幫幫忙！程式後段式副檔<LCD.INC>這部份應該沒問題！

程式太常無法幫你用看的來找Bug，建議先檢查RS-232收發的訊息市府有錯，LCD 顯示程式單獨測試時功能是否正常，把問題分類後依依測試，建議不要一次寫完後再測試。

小弟用PIC16F877的RS232<RX.TX>與SIM100C模組做傳輸，目的是要接收SIM100C模組的回傳值<字串>並顯示於LCM上，電路部份已經無任何問題也可以撥出設定號碼，但是在顯示SIM100C的傳回值卻都是亂碼LCM為WG12864J-YYH-V中英文顯示模組，希望版主或哪位大大幫忙解決一下！小弟程式為下還有<LCD.INC及DELAY.INC兩個副檔>PIC與LCM模組為4-bit傳輸。
