The task is to design and write a software that can be used to control a DMX / RDM capable LED power supply from a computer. The software should be able to send the desired 8-bit or 16-bit DAC values to the power supply and provide or retrieve information from the power supply with the appropriate RDM (Remote Device Management) instructions. The feedback is provided by the measurement result of a measuring instrument capable of serial communication, based on which the DAC values to be sent in the next iteration are to be changed.
