[info] HIP9011 module

[AndreyB]

This is a bit unfinished (untested) and a bit untested (no proof that real knock is detected), at this point I would not bother using it.

Just for the record - here's an assembled board with working SPI:

@ has unreliable hip9011 experience with his board - putting a finger on the chip changes the output level. I like that we see the integration on the output so something is right, but we need a reliable output level

It looks like its in oscillation, it could be a hardware issue but maybe tweaking the control parameters will fix that.

Can you post more about the setup? I don not know what channel is connected to what pin, etc. What is the input signal? Is there some kind of knock simulation, or is the input disconnected?

Oh, also can you zoom in, such that you have only 3 or 4 pulses on the screen.
