VARIABLE FREQUENCY PULSE SIGNAL GENERATION SYSTEM AND METHOD OF SIGNAL GENERATION THEREOF BASED ON SERIAL COMMUNICATION

摘要

Low cost micro-controller based systems suffer from lack of adequate on-chip resources for generating Variable Frequency Pulse Signal (VFPS) output. Traditionally on-chip "capture and compare blocks " coupled with a dedicated timer can be used to generate VFPS output, this approach ties up on-chip timer resource and event counting hardware for VFPS generation , restricting the system capabilities for timer/counter intensive applications. This invention proposes use of on-chip serial synchronous communication channel for generating VFPS output. This approach does not restrict system capabilities for timing/event counting tasks. Many low-cost stand-alone systems do not need synchronous communications and hence the associated hardware can be gainfully employed for VFPS generation.
