Anybody have any software examples of how to write and read I2C using the OpenRISC?

Are you referring to the software necessary to use the I2C project, or to the software necessary to bit-bang an I2C interface from a microcontroller? Assuming you menat the I2C project, I checked the repository for software examples files, but only found a section of the specification that discussed programming examples (chapter 6). Perhaps you could share your work with the project when you are done so that others would have some examples to work with? Dan |

Hello,
you can check this: http://opencores.org/websvn,filedetails?repname=minsoc&path=%2Fminsoc%2Ftrunk%2Fsw%2Fdrivers%2Fi2c.h http://opencores.org/websvn,filedetails?repname=minsoc&path=%2Fminsoc%2Ftrunk%2Fsw%2Fdrivers%2Fi2c.c I have successfully used the code above with the I2C controller IP by Richard Herveille to read out temperatures from an I2C temperature sensor.
