ERR: cam.calibrate. Error performing the "E" command (Adjust camera for current lighting
conditions). This may be caused by a communication error between the Propeller and camera.
ERR: cam.setRes. Error setting the camera's resolution. This may be caused by a
communication error between the Propeller and camera.
ERR: cam.getID. Error retrieving the camera's manufacturer and product IDs. This may be
caused by a communication error between the Propeller and camera.
ERR: eeprom.ReadLong. Error reading calibration data from the external Serial EEPROM. This
may be caused by a communication error between the Propeller and EEPROM or an incorrect
type of EEPROM device.
ERR: eeprom.WriteLong. Error writing calibration data to the external Serial EEPROM. This
may be caused by a communication error between the Propeller and EEPROM or an incorrect
type of EEPROM device.
If the LRF is in an error state, but no error message is transmitted, then there is likely a failure with
starting either the serial communication or auto baud detection cog.
