I2C Interface on c6713 DSK

Other Parts Discussed in Thread: MSP430F2274, TMS320C6713B

Hi,

I'm new to the c6713 DSK. Currently, I'm using c6713 DSK to process some audio, and I need to use some external data from a peripheral chip (MSP430f2274) to enhance the audio processing. I have made the physical connection (using J1 - pin68, pin70, and pin72), and I have the slave code written in MSP430f2274. Now, I need to write a Master TX/RX code for c6713 DSK to pull data from MSP430f2274. However, I'm really stuck in writing the code for it, since I couldn't find any working examples for it. Does anyone have such a working example that you would like to share? Also, any comments or suggestions are welcome! I just need some help badly on this issue.

Thanks in advance!

    Please take a look at the C6000 I2C Reference Guide, SPRU175. It has a section called Programming Guide.

    Hi, RandyP

    Thanks a lot for your suggestions!

    I did see the documentation earlier, and it was helpful. I also found the c6x library supporting the chip with all register definitions and macros in csl_i2c.h and other related files. Do you know if there are other documents that help me understand the csl macros?

    You can get to device documentation easily through the Product Folder for any device, for example TMS320C6713B. The link in red will get you there, or you can go to www.ti.com and do a device search (upper-right corner) for C6713B. In the Product Folder, you will find links for Technical Documentation and for Software and Tools.

    In the Software and Tools section is the link for C6000 Chip Support Library, and the linked page includes the API Reference Guide. This API Guide should also be included in the CSL installation or somewhere in your docs folders in your CCS 3.3 installation. You can also get to it from within CCS 3.3 from the Help menu.

    Regards,
    RandyP
