  • Forum Post: Re: Interrupt priority

    Frank Bormann
    Allessandro, by default all other interrupts, including higher prioritzed interrupts, are disabled when the 28x enters an ISR. This is done in hardware and based on INTM. With the return from the ISR the INTM switch is closed again. This principle is called "non nested". Now, if you like...

    Jorge3559
    I can't seem to access the SPI INT FLAG. I would expect this flag to be a "1" after I send data through the SPI, and I would expect this flag to reset "0" after I read the SPI RX BUFF as per APP Note SPRU059D. Every time I look at the values of these resigeters they remain unchanged...

    Davor
    Thank you, both. We are "pretty" confident that it is not a power or clocking issue in our case. We tried removing parts of the code to try to pinpoint what causes it to crash. The problem with this approach (in our case) is that the crash can occur anywhere from immediately to days after...

  • Forum Post: Re: eZdsp F28335 and enclosed Code Composer

    Magnus Wohlfart
    The eZdsp-Kits are intended for evaluation purposes, that's why the version of Code Composer Studio that comes with them, has a few limitations. One of them is that it will only work with the ezdsp-boards, so even drivers for external emulators will take no effect. If you have your own board...

    Davor
    The flash programmer "knows" that there are initialized sections placed in RAM but cannot "know" if your code is making sure that these sections are initialized - hence a warning. Does you application run from flash, after you reset the CPU?

    Hello, I don's see in Data Sheet from TMS320F28335 the specifications for all 18 PWM outputs, it's only for 16 PWM outputs (TMS320F28332). Anyone know for what are used another 2 PWM outputs???. What is the PWM difference between TMS320F28335 and TMS320F28332??? Thx, Dino

    You could utilize one of the Isolator family of devices. You can hone in on the device that would work for you by using the Parametric Table search . Perhaps the ISO7221A would work.

    BrandonAzbell
    I haven't found anything in the TMS320C28x Optimizing C/C++ Compiler Users Guide ( SPRU514 ) which would allow you to use a switch or pragma to enable the functionality you desire. Section 7.5.2 confirms the behavior that you describe already.

    Hi! Does anybody know, if there is a way to write custom prolog/epilog for interrupt functions? The context save/restore done by the compiler, differs whether the interrupt function calls any other function (this can be easily remedied, by including dummy function call), and it does not save all the...
