最基本的問題，要把 Data Sheet 裡有關 AD 的暫存器看一遍就之道了。
摘自 Data Sheet 裡的說明: ADxPCFGL: ADCx PORT CONFIGURATION REGISTER LOW PCFG<15:0>: A/D Port Configuration Control bits 1 = Port pin in Digital mode, port read input enabled, A/D input multiplexor connected to AVSS 0 = Port pin in Analog mode, port read input disabled, A/D samples pin voltage

下面的program是使用PIC24HJ256GP610驅動1602LCD的~
DRIVER改自站上提供的APP009V2_LCD.c 如果不在PROGRAM中設定AD1PCFGL和AD1PCFGL為0xFFFF就可以操作正常~ 但是在設定AD1PCFGL和AD1PCFGL為0xFFFF之後LCD就不能動了~ 有大大知道那裡出問題了嗎? THX<(_ _)> Attach file: Link only for registered users
