I need to know how an I2C master can be implemented with the PIC16C74A, does the I2C port allows me to do this or do I have to use the subroutines that are given in the application note AN554 of the CD of MICROCHIP. In this document the PIC 16c71 is used and the pins SCL and SDA are been used with the RB0 and RB1 pins. Is it necessary in the 74 to use these same subroutines but with the pins assigned to the I2C port?. If this is so, does the 74 have the capabilities to offer me the I2C port as master eventhough I have to implement the serial port by software?. Greetings, Alex. ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
