又见SYSID问题，弄了两天都没解决，今天参照例程改了device and pin里的设置，解决问题了。顺便把数码管、led无缘无故亮的问题也解决了。

DEVICE:

PACKAGE:FBGA

PIN COUNT:780

SPEED GRADE:ANY

 

DUAL-PURPOSE pins：

DCLK:USE AS PROGRAMMING PIN

DATA[0]:as input tri_stated

data[1]/asd0:同上

data[7..2]:use as regular i/o

flash-nce/ncso:as input tri_stated

other active parallet pins:use as regular i/o

nce0:use as regular i/o

 

unused pins:as input tri_stated with weak pull-up
