Hello TI TIVA community:
I seem to be experiencing a strange issue with respect to the TIVA GPIO settings.
The issue I believe we might have is that we are setting the pin to an output first, and then setting the direction.
In the TIVA platform, can I set the GPIO pin output value prior to setting the pin to an output, and have that value persist?
If so, then I just need to reset the order, and everyone should be happy. If not, then I have to look into a possible hardware change.
This is some code to review:
<Code>
GPIOPinTypeGPIOOutput(PIN_FUNCTION_1);
GPIOPinTypeGPIOOutput(PIN_FUNCTION_2);
GPIOPinTypeGPIOOutput(PIN_FUNCTION_3);
GPIOPinTypeGPIOOutput(PIN_FUNCTION_4);
GPIOPinTypeGPIOOutput(PIN_FUNCTION_5);
GPIOPinTypeGPIOOutput(PIN_FUNCTION_6);
GPIOPinWrite(PIN_FUNCTION_1, 0);
GPIOPinWrite(PIN_FUNCTION_2, 0);
GPIOPinWrite(PIN_FUNCTION_3, 0);
GPIOPinWrite(PIN_FUNCTION_4, 0);
GPIOPinWrite(PIN_FUNCTION_5, 0);
GPIOPinWrite(PIN_FUNCTION_6, 0);
</Code>

GPIOPinWrite(PIN_FUNCTION_1, 0);
GPIOPinWrite(PIN_FUNCTION_2, 0);
GPIOPinWrite(PIN_FUNCTION_3, 0);
GPIOPinWrite(PIN_FUNCTION_4, 0);
GPIOPinWrite(PIN_FUNCTION_5, 0);
GPIOPinWrite(PIN_FUNCTION_6, 0);
GPIOPinTypeGPIOOutput(PIN_FUNCTION_1);
GPIOPinTypeGPIOOutput(PIN_FUNCTION_2);
GPIOPinTypeGPIOOutput(PIN_FUNCTION_3);
GPIOPinTypeGPIOOutput(PIN_FUNCTION_4);
GPIOPinTypeGPIOOutput(PIN_FUNCTION_5);
GPIOPinTypeGPIOOutput(PIN_FUNCTION_6);

Any feedback or input is welcomed and appreciated!
Thanks again!
