Multiple Boards

[tpy37]

Hi Joshua,
Hope you are doing well.
Just a quick question.
Does AcousTools support multiple boards beyond two boards?
Best,
Tatsuki

Hi,

AcousTools doesnt really care about 'boards' a such - as long as you have a tensor of the board positions (XYZ) then it should work. If they're not oriented along the z-axis you should be able to give a tensor of the normals to the transducers too to give the orientation. Make sure the shape is the same as the pre-build ones (Obviously you can change the sizes but make sure the order of the dimensions are the same).

If you look in acoustools.Utilities.Boards there should be some functions there to set up transducers as well as built in variables for the standard ones (and some to load a board from an stl!)

Let me know if you need anything

Hi, thanks for the quick response. Sorry for the lack of clarity. I meant for connection with OpenMPD drivers.
When there are more than two boards present and need to send FTDI communications, can we keep appending to the board ids?
Like (1000, 999) to (1000, 999, 2000) etc?

Hey. I havent actually tried it but i think in theory yes? Im not entierly sure about the driver end as just sends the signals over to OpenMPD. I also wouldnt be certain about the order you would need to send the transducers signals in - i have a function that swaps acoustools <-> openMPD orders but im not sure how OpenMPD expects the order past 512 transducers. Sorry thats not too helpfu

There are export functions eg to CSV if you wanted to compute the holpogram with AcousTools and then put it directly into OpenMPD/ somethinf you write yourself!

The C code i use to communicate with OpenMPD is here if thats helpful https://github.com/JoshuaMukherjee/Levitator
