謝謝版主的回覆…感謝!!!

參照：
傳給函數的參數不對也太少了，請參考 C30 Libraries User's Guide 的說明。

參照：
應該是忘了 include timer.h 的檔案了。

請問各位前輩…我是使用APP021模擬板，主控晶片是dsPIC33FJ128MC708，可是在編寫程式時，無法成功使用
以下這些函數，則output示窗會出現以下六行訊息，是在這裡的寫法不同，還是原因如何，煩請前輩們解答，謝謝。

ConfigIntTimer1( )
OpenTimer1( )
BusyADC1()
CloseADC1()
ConfigintADC1()
ConvertADC1()
OpenADC1()
ReadADC1()
SetChanADC1()


In function 'Init_ADC'
error: too few arguments to function 'OpenADC1'
error: too few arguments to function 'SetChanADC1'

In function `main'
