Decoding eRPM Telemetry Waveform from ESC

[RaulIQ]

Hi,

I'm working on reading telemetry data from a DShot/Bi-Directional DShot ESC and I need help decoding the waveform.

I read the article DSHOT - the missing Handbook
which explains that the ESC sends a 21-bit telemetry frame. However, I’m struggling to understand how to interpret the waveform I captured when sending a zero (Motor-Stop) command.

Here is a screenshot of the waveform I received:

According to the article, this should represent something like 010001011101000101110, but I can’t figure out how to visually identify these 21 bits in the waveform.

How do I correctly read and split this waveform into the 21 bits used by the bidirectional DShot protocol?

Any guidance or references would be greatly appreciated.

Thank you!
