关于Protues里面仿真PIC单片机
Protues支持仿真PIC单片机里面的EEPROM存储器的读写吗？如果支持，那么我这个问题是指的啥：Modification of EECON1 whilst a read or write is in progress is not ambiguous and not supported .EECON1 is unmodified.这个是在Protues里面提示的。我自己的翻译是：EECON1的修改，同时在读或写的过程中是明确的和不被支持的，EECON1没有被修改。 没有人回答么.............自己顶............... 我自己的翻译是
Your translation is wrong, by a mile and some.
the message says that you cannot modify EECON1 when a read/write has not finished. Try to modify EECON1 when there is action no eeprom operation - -没用过仿真中读取EEPROM，静待大神，帮顶 PICC自带的EEPROM_ROUTINES文件内的函数 就可以用的啊 proteus仿真pic内部EEPROM 可以的

没有懂你的意思....是需要用另外的函数么.....可以具体点么.... millwood0 发表于 2013-8-19 09:23 static/image/common/back.gif

你的意思我懂了......
这个是写的函数：
void WriteData(uchar Data,uchar Address)
{
//EECON1bits.FREE=1;
EECON1bits.EEPGD=0;
EECON1bits.CFGS=0;
EECON1bits.WREN=1;
// EEADRH=0;
Cout=0;
EEADR=Address;
EEDATA=Data;
EECON2=0x55;
EECON2=0x0AA;
EECON1bits.WR=1;
while(1)
{
if(EECON1bits.WRERR==0) //这里是检测是否写完成
{
break;
}
if(Cout==200) //这里是限制等待的时间。。。。
{
break;
}
++Cout;
}
EECON1bits.WREN=0;
}
这个是读的函数：
void ReadData(uchar *Data,uchar Address)
{
// EEADRH=0;
Cout=0;
EECON1bits.EEPGD=0;
EECON1bits.CFGS=0;
EEADR=Address;
EECON1bits.RD=1;
/*while(1)
{
if(EECON1bits.RD==0) //这里是检测是否读完成，不知道用这种方式可以不...不太了解
{
break;
}
}*/
*Data=EEDATA;
}
以上是我的两个函数...不知道写错了没.....
