感謝jackylts/cct1210/master前輩的指點,已解決,問題就是在這理,直接設定是不錯的選擇

參照：
請參考http://www.microchip.com.tw/modules/n ... de=flat&order=ASC&start=0 拿掉UART_TX_PIN_NORMAL 這一行,編譯雖然過了,實際燒錄至硬體中uart中的TX,是完全沒訊號的,所以等於白搭. 順便小聲告訴你,若可以,直接設定有關uart暫存器的值會比較穩當的.

偷懶的話直接手動定義
#define UART_TX_PIN_NORMAL 0xF7FF 這行找不到似乎是因為用了4011以後，MACRO用了_dsPIC30F4011__後面定義區段，而不幸的的 UART_TX_PIN_NORMAL並沒有在其中。

在Program Files\Microchip\MPLAB C30\src\peripheral_30F_24H_33F\include\uart.h裡面,
UxSTA的bit定義跟文件不一樣 內容如下 /* defines for UART Status register */ #define UART_INT_TX_BUF_EMPTY 0xDFFF /* Interrupt on TXBUF becoming empty */ #define UART_INT_TX_LAST_CH 0x7FFF /* Interrupt when last character shifted out*/ #define UART_INT_TX 0x5FFF /* Interrupt on transfer of every character to TSR */ #define UART_IrDA_POL_INV_ONE 0xFFFF /*IrDA encoded, UxTX Idle state is '1' */ #define UART_IrDA_POL_INV_ZERO 0xBFFF /* IrDA encoded, UxTX Idel state is '0' */ #define UART_SYNC_BREAK_ENABLED 0xFFFF /* Send sync break on next transmission */ #define UART_SYNC_BREAK_DISABLED 0xF7FF /* Sync break transmission disabled or completed */ #define UART_TX_ENABLE 0xFFFF /* Transmit enable */ #define UART_TX_DISABLE 0xFBFF /* Transmit disable */ #define UART_TX_BUF_FUL 0xFFFF /* Transmit buffer is full */ #define UART_TX_BUF_NOT_FUL 0xFDFF /* Transmit buffer is not full */ #define UART_INT_RX_BUF_FUL 0xFFFF /* Interrupt on RXBUF full */ #define UART_INT_RX_3_4_FUL 0xFFBF /* Interrupt on RXBUF 3/4 full */ #define UART_INT_RX_CHAR 0xFF7F /* Interrupt on every char received */ #define UART_ADR_DETECT_EN 0xFFFF /* address detect enable */ #define UART_ADR_DETECT_DIS 0xFFDF /* address detect disable */ #define UART_RX_OVERRUN_CLEAR 0xFFFD /* Rx buffer Over run status bit clear */

請教各位前輩
我使用mplab 8.43 +C30 IC為dsPIC30F4011 使用周邊函式庫,我有加入<uart.h>header file 參考dsPIC30F_dsPIC33F_PIC24H_UART_Help.htm 為何下以下的參數時會有問題 U1STAvalue = UART_INT_TX_BUF_EMPTY & UART_TX_PIN_NORMAL & UART_TX_ENABLE & UART_INT_RX_3_4_FUL & UART_ADR_DETECT_DIS & UART_RX_OVERRUN_CLEAR; 出錯的地方在UART_TX_PIN_NORMAL 這一行 拿掉就OK了,以下為錯誤訊息 test.c:170: error: 'UART_TX_PIN_NORMAL' undeclared (first use in this function) test.c:170: error: (Each undeclared identifier is reported only once test.c:170: error: for each function it appears in.) test.c:195:2: warning: no newline at end of file 請問這是何原因,一直找不出來,謝謝!!!
