santook Member Nov 9, 2016 #1 On C language,if we need read one parallel port,like C51 P0 or AVR PA,We just to read: unsigned char value; value=P0; //value=PA; Now ,How to read parallel on B4R?

santook Member Nov 9, 2016 #5 I have solved it, I used the 74HC165 chip, using parallel to serial. This can be read parallel and do not take up IO resources.And more simple. Upvote 0
