TMS320F28069: Gpio integrity test

Chandrakant Pal
Intellectual 500 points
Part Number: TMS320F28069


Hi All,

Is there a way to find out whether the GPIO is working properly of the microcontroller while running the application or is there any interrupt generated if the GPIO is damaged of the microcontroller so that further actions can be taken in the application code?

Thanks and Regards,

Chandrakant Pal

    Chandrakant,

    There are no flags or interrupts that will occur when a GPIO is damaged. If you would like to monitor an output you could connect an extra GPIO, configured as an input, to the GPIO you wish to monitor. This will allow you to read and determine the logic level of that pin. Now, if for some reason both pins are damaged then it is possible that you may receive some indeterminate readings.
