1. Control circuitry for a light emitter, the control circuitry comprising:
a frame buffer to store image data, the image data defining how to electrically drive the light emitter;
a universal asynchronous receiver/transmitter (UART) interface coupled to the frame buffer, the UART interface configured to receive the image data from an external element; and
conversion circuitry coupled to the UART interface, the conversion circuitry to receive the image data in a first bit length from the UART interface, translate the image data into a second bit length and provide the data in the second bit length to the frame buffer.
