RtPerfMonitorEX

Description

This utility monitors RTSS CPU usage. It also measures RTX HAL clock tick intervals and latencies from HAL ISR to SRTM IST. For backward compatibility, it includes measuring SRTM latencies. It optionally uses the timer to drive the sound speaker (a 500 us timer will generate a 1 KHz square wave). Any significant timing jitter will produce a frequency wobble easily picked up by the human ear.
