What are the left GPIOS when using Wolfson Audio Card ?

Former Member over 11 years ago

I would like to use some gpios for my stuff beside using the wolson audio card, but I can not find which are the GPIO that are still available.

Can some one help me about this ?

Best Regards

You can use I2C (I believe the Wolfson card uses I2C as well), however there is no breakout for the I2C pins, so you will have to - at a minimum - solder a few pins to use it. I've successfully driven a RTC and OLED display from the bus, and plan to add a GPIO expander. I went a bit overboard and replaced the header with a stacking header, but I imagine you could solder a few pins to the existing ones.

Yes, you can do that. See here: Re: Access to 5 GPIO pins with Wolfson Sound Card
