Hi, I want to create a high level analyzer for a motors HALL signals. The signals are three digital signals that toggle in a specific pattern such that they can be read as a binary value with 3 bits.

From what I can see there is an input analyzer for the scripts but there is no clock signal for these signals.  
My thought process is like this:

1. Trigger on every rising and falling edge.
2. Calculate a value based on the value of all signals
3. Output the value

Is it possible to do this?

High-level analyzers (HLAs) depend on data coming from the [low-level protocol analyzer SDK](https://support.saleae.com/saleae-api-and-sdk/protocol-analyzer-sdk), or a built-in [low-level protocol analyzer](https://support.saleae.com/protocol-analyzers) with [`FrameV2` support](https://support.saleae.com/saleae-api-and-sdk/protocol-analyzer-sdk/framev2-hla-support-analyzer-sdk).

For this use case, I think the [simple parallel analyzer (no clock)](https://github.com/Zweikeks/saleae-logic-SimpleParallelNoClock-Analyzer) could provide the `FrameV2` decoded data you’d need to input into your own [custom HLA extension](https://support.saleae.com/extensions/extensions-quickstart).
