Hi,
Does any one knows that the CodeVision for AVR use Hardware or Software I2C in Automatic Program Generator OR its include I2C library?
Like the DS1307 library is using Hardware/Software I2C?
thx
 

codevision i2c

It uses hardware I2C.
 

avr i2c

Hrm - not sure about that. I can generate code for I2C and DS1307 for AT90S2313, which has no hardware I2C.

Looking at the .lst file, it appears to be all software I2C ...

Well, I think we're both right.
The tab I2C in the CodeWizardAVR is for software I2C and the tab 2 Wire (I2C) is for hardware I2C.
The tab 2 Wire (I2C) only appears when you have chosen a device with hardware I2C (2 Wire) at the Chip tab.
 

avr i2c library

Hi,
2 WIRE I2C is hardware, for but slave mode only as much I understand.
So the libs like DS1307 etc are using software I2C. 8O
