using both dpi and i2s on bank 0

Thu Jan 24, 2019 4:22 pm

someone knows ifit is possibile to use dpi18 (for controlling head-mounted display) and i2s (for microphone/speaker) placed on bank 0 ?
From trails it seems that enabling dpi mode disables all the other peripherals. I tried to modify the /boot/config.txt without effect.
Is there an option to overlay the default pin of the dpi18? (for instance move the GPIO 18-19-21 to GPIO 22-23-24 )
Due to some system's contraints it is mandatory to use only the bank0.

Did anyone found the way to use dpi18 and i2s at the same time on bank0? I'm too interested in the answer.... Thanks!

Look here for DPI details https://www.raspberrypi.org/documentati ... /README.md

As you can see from the mode table I2S is in using GPIO which are used for green in DPI mode.
So, if you're fine with loosing tons of color information you can write your own overlay for DPI+I2S

But - to answer you question: no, DPI18 and I2S on page 0 only is not possible.
