Output internal signal to GPIO 21-25 on C5505 ezDSP usb stick

filhodamusica

Hello,

I'm trying to output a bitstream so I can see it on the osciloscope (instead of using the audio output). I want to use a GPIO pin (22 per example) but I can't find a way to control it.

Wich functions must I use?

Thanks for the help,

André

GPIOs are multiplexed with other peripherals controllable via EBSR. I/O direction is configured by GPIO direction registers. Refer to GPIO User's Guide for details.

Regards.
