Embodiments of systems for calibrating transducer-including devices include a board support structure, one or more motors, a motor control module, and a calibration control module. The board support structure holds a calibration board in a fixed position with respect to the board support structure. The motor(s) rotate the board support structure around one or more axes of a fixed coordinate system. The motor control module sends motor control signals to the motor(s) to cause the motor(s) to move the board support structure through a series of orientations with respect to the fixed coordinate system. The calibration control module sends, through a communication structure, signals to the transducer-including devices, which are loaded into a plurality of sockets of the calibration board. The signals cause the transducer-including devices to generate transducer data while the board support structure is in or moving toward each orientation of the series of orientations.

Methods and apparatus for calibrating transducer-including devices

Embodiments of packaged transducer-including devices and methods for their calibration are disclosed. Each device includes one or more transducers, an interface configured to facilitate communications with an external calibration controller, a memory, and a processing component. The external calibration controller sends calibration commands to the transducer-including devices through a communication structure. The processing component of each device executes code in response to receiving the calibration commands. Execution of the code includes generating transducer data from the one or more transducers, calculating calibration coefficients using the transducer data, and storing the calibration coefficients within the memory of the device.
