Is this right? Do you have a manual what information can be exchanged between Raspberry Pi and the display?<br /> <br /> I&#039;ve also seen that one switch is not populated on the board. If it should be possible to expand the board with a GPIO controlled via I2C it would be very helpful because DPI needs a lot of GPIOs.&lt;!-- migrated from Comments; original IP: 88.66.73.76 --&gt;</div> 88.66.73.76
