The CURVACE sensor uses two main configuration parameters: framerate and framenumber. These parameters are sent from the PC to the Readout Board over the USB connection. The readout board sends this configuration to the top and to the bottom controller of the cylindrical CURVACE sensor via SPI.
Both controller send the received configuration back to the Readout board for validation which itself sends these two configurations back to the PC. If one of these configurations does not match an error occured and the operation should be aborted.
