5.2.3 PCC Camera Connector
A 2x10, 100-mil pin-header footprint for camera connector is implemented to give access to the SAM E54's Parallel Capture Controller (PCC). The footprint is compatible with common ArduCAM modules.
Info: The PCC
connector is not functional by default due to shared functionality with Ethernet,
QTouch, SD Card, EXT1, and EXT2. If using the PCC, you will partially or fully loose the
ability to use these other functions.
Info: Soldering is required to get the PCC functional. Refer to
Kit Modifications for details on modifications needed.
Tip: The DEN1 and DEN2 signals connected to VSYNC and HYSNC on the PCC camera
connector are used to tell the PCC module when there is valid data to sample on the data
pins. If interrupts are required when the DEN1 and DEN2 signals changes, the I/O pins
(PA12 and PA13) has to be multiplexed to the EIC function in the GPIO module. The PCC
module will still sample the DEN pins when they are multiplexed to the EIC
function.
