In my project I need many I/O pin. There is some chip than can expand the digital I/O PIC capacity? I found a Elan Microeletronics chip that have a I2C input and 14 digital output (EM83010). There is something similar with more pin and of another producer? Thanks in advantage. =================================================== Alboni Giorgio Faenza (Ra) ITALY E-Mail: rac1337@racine.ravenna.it http://www.geocities.com/SiliconValley/Heights/5444 (Last Update: 29/09/97) ===================================================
