TMS320C6657: How to verify GPIO pins

I was able to successfully run the GPIO_LedBlink TestProject.

However, since the TMDSEVM6657LS board does not have any gpio pins that are directly connected to an LED, how can I confirm that the GPIO pin is being written to correctly.

Based on the schematics, it looks like on the 80 pin expansion header, pins 78 and 80 are for GPIO 14 and GPIO 15.

If I change the GPIO LED inside the example project to be 14 and 15 (instead of the default value of 8 and 9), could I theoretically put a scope on pins 78 and 80 on the expansion board and see it?

Thanks

Cynthia,

True. Good point !

Yes, you could try that, as well.

Alternately, You can connect a multimeter and check -- when you write the values 0 and 1.
