Hi,

generally I2C is a good and simple choice.

There are several communications ports you could use: I2C, SPI, SCI. There are examples for all of these communication ports for both C2000 and MSP430 at the following links:

I need code examples to make an i2c interface between a msp430F2013 and dsp 28335?

There are code examples for both the MSP430 and TMS320F28335 available that use the various peripherals discussed. You will need to tailor these for your application, but they will offer a good starting point.

The MSP430 code examples for the MSP430F2013 are found here.

The TMS320F28335 code examples can be found in the controlSUITE software download.

I have same problem that Gaston. I need to make an interface between dsp 28335 and msp430f2013.

I can only make it with 2013 as master (example code msp430x20x3_usi_8.c in slac080e)

and the 28335 as slave (example code lab12_1.c modified in CC2000 Teaching Materials C2833x_CCS4).

But I want to make an interface with the 28335 as master and 2013 as slave.

Sorry I don't say that the communication selected is I2C.

Brandon,

I'm trying to make an I2C interface between a f28335 (master) and a msp430f2013 (slave)

The f28335 send bit start + 7bit address + bit write + one clock (ack)

I can't send this ack from msp2013 to 28335

Please help me?

As I mentioned in my last post, I provided links to the software examples of the MSP430 and TMS320F28335 that have the appropriate configurations of the TMS320F28335 as the I2C master (i2c_eeprom example) and the MSP430 as the I2C slave (msp430x20x3_usi_15.c).

Please use these as a reference. They can serve as a starting point.
