Hi everyone. I'm working on a project with acoustic ghost imaging that utilizes a 10x10 array of speakers to blast sound an at object in order to take a "photo" of it. To do this, I am planning on having one "master" Teensy 3.5 generate a random checker board - type pattern of random high and low squares over that 10x10 array, then send this pattern to three "slave" Teensy 3.5's. Each of the slaves will correspond to a section of the 10x10 array, and if there are high squares in their portion, then those speakers turn on.
The issue that I am running into is that I am not sure how to actually use the master Teensy to send orders to the slaves. I've looked into RS-485, I2C, and SPI, and I am not quite sure which would be best. This rig will be small, so I figure RS-485 won't be best. I'm not exactly sure how I2C works honestly, but it is seeming like SPI would be my best bet. All in all, though, I am not entirely sure.
If anyone would mind giving some advice, I would be very appreciative.
