#125285 - software I2C Responding to: ???'s previous message |
i have implemented software I2C with 11.0592 Mhz crystal i get data rate of 62,631bps but i am sure you can get more with higher crystal freequency and reducing the NOPs in the macro "HOLD"
take a look at http://www.rickeyworld.info/download18.html its implemented in C.. if you want in assembly its also available there. hope this will help. regards, ajay bhargav |

Maybe not a good idea | 01/01/70 00:00 | |
7816 via UART | 01/01/70 00:00 | |
WHY? | 01/01/70 00:00 | |
I use bit-bang instead of hardware i2c | 01/01/70 00:00 | |
as often as with an UART | 01/01/70 00:00 | |
