最後查到的大多都會連回microchip的討論區
除了Google
也能使用 microchip 右上角的 "搜尋區塊" 搜尋

哈~
一開始我還疑為我拿到瑕疵品
想說自認倒楣算了
原來資料都在另一塊裡面!!

參照：

哈 按下去是Low

我現在遇到一個新的問題!!
我想要的是 按"一"下S1後 LCD 顯示 PUSH S1 接著回歸 NO PUSH
執行結果確實有顯示 PUSH S1 但 Delay 微小時間後 會變成 NO PUSH 形成 PUSH S1與NO PUSH 交互顯示
若再按"一"下S2 則變成 PUSH S2與NO PUSH 交互顯示

請問這會是甚麼原因??

主程式我改成
int main(void)
{

LCD_Delay200usX(50) ;

ADC_Initial() ;
PMP_Initial() ;
Timer1_Initial();
OC_Initial() ;
LCD_Initial() ;
IOInit() ;

while(1)
{

LCD_SetCursor(0,0);
putsLCD(LCDString);
LCD_Delay200usX(500) ;
LCD_SetCursor(0,1);
putsLCD(LCDString);
LCD_Delay200usX(500) ;

ReadSwitch();

switch (Sw)
{
case 1: //S1 Pressed
DisplayS1();
break ;

case 2: //S2 Pressed
DisplayS2();
break ;

}
PORTBbits.RB3 = 1 ;
PORTBbits.RB5 = 1 ;
}
}

nicecookie 你好
很抱歉我沒有詳細說明我的問題 Sorry

debug -> Run 中
無按下任何按鍵 LCD螢幕顯示 NO PUSH
按下 S1 LCD螢幕顯示 NO PUSH
按下 S2 LCD螢幕顯示 NO PUSH
按下任何按鍵 LCD螢幕顯示 NO PUSH

用中斷檢查發現
switch (Sw) <==若在此設為中斷點，則可以中斷 。
{
case 1: //S1 Pressed
DisplayS1(); <==若在此設為中斷點，則不能中斷 。
break ;

case 2: //S2 Pressed
DisplayS2();
break ;

}

用watch 觀看Sw的值 無論按下S1、S2等任何按鍵 Sw的值 均為0x00 並無變化

不曉得 這樣的資料夠不夠齊全?

使用PIC24FJ128GB106
按下按鍵開關SW1 ，LCD顯示 "PUSH S1"
按下按鍵開關SW2 ，LCD顯示 "PUSH S2"

編譯沒問題
但是當我按下任何按鍵開關 均無反應!!

請問有可能是哪邊出了問題??

首先 我要感謝所以觀看及回覆我的問題的前輩
因為你們，我才得以進步，找出問題，解決方法!!
目前我已經可以做到接收GPS訊號並顯示資料!!
但卻跑出顯示的資料為亂碼!!(像是'['、'^'、日文、奇形怪狀的文字)
距離成功只差臨門一腳!!!
各位前輩方便的話，請幫我看看哪邊出錯導致顯示資料的時候為亂碼!!

我使用PIC24FJ128GB106
欲從PC上的超級終端機按字元，使PIC24FJ128GB106的LCD上顯示所接收到的字元
unsigned char RX_DATA ;
RX_Data= ReadUART1();
使用ReadUart1 Function
This function returns the content of UART receive buffer (UxRXREG) register.
接著丟給RX_Data這個參數
RX_Data的value是16進位這個沒錯吧!?
我想請教的是，我在PC上的超級終端機每次都按下a
我從watch上看U1RXREG、RX_Data的Value
第一次
U1RXREG的Value為0x004F
RX_Data的Value為0x00
第二次
U1RXREG的Value為0x000F
RX_Data的Value為0x4F
第三次
U1RXREG的Value為0x004F
RX_Data的Value為0x0F
第四次
U1RXREG的Value為0x000F
RX_Data的Value為0x4F
會是我中斷點設錯嗎??
還有為什麼我按下a，結果LCD顯示O
我程式哪邊寫錯??請各位前輩多多指教!!!
特別想請教我的U1MODEvalue這邊有沒有設錯??因為我之前就這邊設錯導致整個執行錯誤!!
