Retesting the Camera (GC2145) on the giga with the giga display showed that the zephyr video api changed which required updating the camera library, see PR#135 for changes. After making the changes camera visualizer sketch seems to do nothing, i.e, nothing sent to processing visualizer sketch etc,

Did notice that in debug window:

[00:00:17.789,000] <inf> usb_dc_stm32: PWR not active yet[00:00:17.911,000] <inf> usb_cdc_acm: Device suspended[00:00:18.136,000] <inf> usb_cdc_acm: Device configured[00:00:23.078,000] <wrn> video_stm32_dcmi: HAL_DCMI_ErrorCallback[00:01:17.598,000] <wrn> shell_uart: RX ring buffer full.[00:01:17.604,000] <wrn> shell_uart: RX ring buffer full.

which does not show the usual spew when the camera is working.

However if I remove the shield and put camera directly on the giga it works.
