7" Display combined w/ Wolfson Audio - possible ?

[EllipsenPark]

Hi everybody,

would it be possible to use the Wolfson Audio Card and the official Display in combination ?

I've tried, but it seems as if the necessary GPIO pins are not routed through the Audio card ...

Regards,

The bigger problem is that the Wolfson kernel won't have the official display code built in to it. They don't keep up with all of the kernel development. My model B with the old Wolfson card is running with a kernel built in April 2015.

The support for the Wolfson/Cirrus cards isn't just patchy, it's 100% non-existent.

Aside: I'm using the new Wolfson on a Raspberry Pi 2 ..

Ok ... wasn't really aware that you'd need a special kernel. Makes it pretty much unusable ...

On the hardware side, though, it's possible to mount both, you just need to find the right extension headers
(pin 9 for SCL, pin 14 for SDA) ...

?? The display doesn't require any gpios unless using it old rev B, and you say you're on a Pi2. I2c-0 is routed up the flex to the display.
All 40 pins on the main gpio header are available for your use to the audio card.

Getting a working kernel is another matter.

Hmm not really, when i don't connect the SCL and SDA cables, the screen just stays black ...

I've followed the instructions as presented here:

Sorry, i was wrong, it works perfectly fine if i use the usb powering method, without the jumper wires ... don't know what i did wrong before ... strange ...

Glad you got there. I was just writing a response to say I knew it worked that way as that is how mine is hooked up, though I am using jumper wires for my power (pins 2&6). The SDA and SCL lines really are only needed for old rev B's.

I'll try to remember to ping Pi Towers to see if a documentation update is in progress for the display as there are several partially incorrect guides out there.

That little rainbow square means your power supply isn't good enough. It's not "a little activity square". Since power demands are variable depending on how much work the CPU is doing I can see how you'd be confused by it.

Oh, ok ... but i'm using the same adapter as before ...
