    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...

    BrandonAzbell
    The better document to reference for details on the Instruction Set is the TMS320C28x DSP CPU and Instruction Set Reference Guide ( SPRU430 ) on page 6-345. Also look at Section E.3.3 for the SUBCU instruction on the C28x, which the F2808 is based.

    Hi! I'm currently working with a DSP PFC_System example for the 2808 dsp. The service routine in the example, which controls the PWM, is written as a macro in assembly [^o)]. I had to convert this assembly macro to C-language which is easier to understand. In the macro there is a instruction...

    BrandonAzbell
    BryanHughes I'm doing some work with SPI, and I'm in need of some clarification. Does the F2808 require the SPISTE pin to be used, or can it be ignored (aka GPAMUX set to GPIO mode on the SPISTE pin)? I'm short on GPIO space and would like to use the SPISTE pin for GPIO purposes. The...

  • Forum Post: Re: SPISTE pin on F2808 clarification

    Mitja Nemec
    It depends whether DSP is a master or a slave on the bus: If it is master, the SPISTE pin is optional, but you have to be careful how your slave devices synchronize to the SPI bus. If the DSP is slave, i assume the SPISTE pin is necessary, though I am not certain as I never tested this mode. ...

  • Forum Post: Re: SPISTE pin on F2808 clarification

    Frank Bormann
    SPISTE is used when the 28x operates as SPI- slave. In this case SPISTE is the "Chip select" signal, which allows a master to address the 28x. In that way a master is able to communicate with more than one slave on the same interface, including the C28x-slave. If the C28x is in Master Mode...

    So I did some testing with the F2808 in slave mode with the SPISTE pin set as a GPIO pin...low and behold it worked. I did a stress test with about 30,000 transfers to and from the slave device and there were no problems. Undocumented trick I guess. I'm not doing any SPI-bused transmissions in my...

    I'm glad you found a way. After reviewing your post, i looked at the TMS320x280x, 2801x, 2804x Serial Peripheral Interface (SPI) Reference Guide (SPRUG72). On page 12 in Section 1.1.1 there is a figure, Figure 1-2, of the SPI peripheral block diagram with some detail on how the various control bits...
