Compiler/C2000WARE-MOTORCONTROL-SDK: is07 on standalone mode doesn't work

hello,

I drive motors with CCS, and i want to use the flash mode, in order to make this practice without a computer. I have add some GPIO to control the rotating way and the speed. The initial is07 program doesn't work in flash mode because as soon as I unplug the current source and replug it, it doesn't work anymore. i retried without unplug the JTAG connexion, and the "moduleOverCurrent" became "1" as soon as I unplug the current. It's not suprising but maybe we could change it.

I have think about a GPIO which can control the variable "motorVars.flagRunIdentAndOnLine" but I failed. The GPIO is well wire, I can see it when i press the button, the concerned line (GPIO 0's line ) takes value "1" but the"motorVars.flagRunIdentAndOnLine" don't evolve at all.

Here was my code lines for a simple test (to see if i can influence a variable with a GPIO as simply as I guessed) :

GPIO_setPadConfig(0,GPIO_PIN_TYPE_STD);

GPIO_setDirectionMode(0,GPIO_DIR_MODE_IN);

if(GPIO_readPin(0)== true)

{motorVars.flagRunIdentAndOnLine = 0;

}

Please use the "Flash_lib" build configuration in the project, and take a look at the following link.

Hello,

I already see this thread :

But I don't know how to boot the GPIO state.

Please refer to the TMS320F28004x Microcontrollers Datasheet or Technical Reference Manual. Set the boot mode pins (GPIO24 and GPIO32) by pulling up these two pins to high.

You might take a look at the documentation below if you are using the launchxl-f280049c kit.

C2000 Piccolo F28004x Series LaunchPad Development Kit (Rev. A), SPRUII7A, http://www.ti.com/lit/ug/spruii7a/spruii7a.pdf

If you haven't had a chance to look at the workshop material, I think this will help demystify some of the terminology and architecture as well.

hello,

Thank you for these docs. I think the Flash mode works but the problem is that when i unplug the current, the variable "ModuleOverCurrent" becomes high and it force "motorVars.flagRunIdentAndOnLine" to become 0. so when i replug it's obvious that my motor couldn't start anymore.

So the solution, i think, is to put off the "motorVars.flagRunIdentAndOnLine" before unplug the current and when I replug, put it to "1". when I try it with the USB connexion is on, i can cur the current of and make my test going well. i Just need to put "motorVars.flagRunIdentAndOnLine" high.

I already tried to control it like the speed or acceleration but it doesn't work so please help me to change this variable through a GPIO button. i know how to wire it, the button is ready, but I don't know how to call this variable.

thank you for your attention,

Best regards.

Add a long wait time before the following code to ensure the board power-up well.

//
// enable debug interrupts
//
HAL_enableDebugInt(halHandle);
