Abstract

Low pin count microcontrollers are used in numerous applications, especially in power control. Pin number reduction complicates real–time monitoring and debugging. Two modulation techniques for transmission data using PWM (Pulse Width Modulation) channel without significant influence on main application of this channel are proposed in this paper. Two modulation techniques: Additive Pulse Width Fluctuation and Differential Pulse Width Fluctuation are proposed with appropriate demodulation methods.
