Title: disply 4/7 segment with 2pin(7 segment 2 serial) Post by: samir_1982 on January 21, 2009, 06:17:47 06:17 Hi
This project is very good for 7-segment.only 2pin use for 4/7 segment disply source code http://kavirkit.com/kavir/2007/projects/avr/Serial%20LCD-7-SEGMENT%2074164.v2.0.zip password:www.kavirelectronic.ir other version http://kavirelectronic.ir/fa/modules.php?name=Content&pa=showpage&pid=4 ;) Title: Re: disply 4/7 segment with 2pin(7 segment 2 serial) Post by: LEAS on January 24, 2009, 11:00:20 23:00 74164 shift register + 16x2 LCD 44780 based. 4-bit interface, but 1 pin of 8031 MCU needed. Proteus simulating picture and files. I program thise, but not build in reality.
