    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: http://focus.ti.com/mcu/docs/mcuflashtools.tsp?sectionId=95&tabId=1538&familyId=342 http://focus.ti.com/mcu/docs/mcuflashtools...

    The only documentation regarding the I2C is the reference guide at the following link: http://focus.ti.com/general/docs/techdocsabstract.tsp?abstractName=spru721a Besides this you can perform a Google search for I2C and find several tutorials for the peripheral. One good link for learning about I2C...

    Hello. Is there any good primer or user guide that can give me enough insight on how the I2C peripheral works? I have read the complete documentation many times and looked to several examples, but still some of the information is confusing. For example, sometimes when I configure the module as a...

    Dear all, I'm on a firmware design for new system based on TMS320F28335 DSP. I have utilised the I2C bus for interfacing six port expander IC's and one RTC chip with main DSP. In my I2C driver, when I try to communicate, only address byte is seen on data lines. The signal starts with a start...

    I don't have any sample code to share, unfortunately, but I think we can get this figured out fairly quickly. Would you describe the I2C transaction that you are implementing when writing to the output port register of the PCA9534A? I suspect it is just one large series of consecutive writes...

    hi Folkz, We are using the PCA9534A port expander interfaced with the TMS320F28335 . We could write to the port expander and test it (writing values to the Output Port Register. and checking the status of the port in CRO) But we are unable to read the data from the PCA9534A[:(] . Is their any one...

    I find that the problem seems to be related to the FIFO TX buffer size TXFFST register. On first transmission it is still empty, however when transmitting again (now buffer size 14) the buffer reaches it's maximum size of 16 and seemingly will not take on any more data after the address is bytes...

    Where is this code snip taken from? The I2C peripheral module itself has an Interrupt Enable Register and Interrupt Status Register as illustrated in the TMS320x280x, 2801x, 2804x Inter-Integrated Circuit (I2C) Reference Guide ( SPRU721 ). All of the interrupt sources are represented by a bit in the...
