2022-11-09 (W) PoweredInlineSkatesRev2 Checking PWM fidelity

I wanted to check if my timing pulses were reliable or if the receiver unit gave the ESC jittery signals. I wrote an Arduino sketch to measure the pulse widths and report their length in microseconds. I connected this to the subject by its ESC port, so they were powered in parallel.

I started the system and the receiver connected to the transmitter via Bluetooth. The third controller with my new code started relaying data, and I monitored the changes on a serial plotter. If I hovered at a particular frequency, the timing jittered, but I wonder if it's enough to cause the problems I felt while testing. I want to compare these results with a dedicated servo controller.
Not all that smooth
