Emulate i2c
PostPosted: Tue Apr 21, 2009 6:16 am     Reply with quote
Hi , I'm working with pic12f683 that doesn't have I2c hardware. Are there any library that emulate i2c? I need it because I want to comunicate with a I2c eeprom.

Thank you at all Very Happy

The existing CCS I2C code, will automatically generate an 'emulation', if the hardware doesn't exist on the chip, or the pins you select. But _only_ for a master device.
So long as you don't need a slave (_very_ hard to do in software), just use the standard I2C functions.

Best Wishes
