Magnetic imaging tile max frame rate

Hi All,

I purchased the Magnetic Imaging Tile and I’m trying to get as fast of a frame acquisition as possible. The documentation says this can be achieved at 2000 Hz using the ChipKit MAX32. Although the ChipKit MAX32 can still be purchased, it is an older product and would have required a special order. I also figured that a fast MCU such as the Teensy 4.1 could potentially achieve even higher frame rates. However, unfortunately, I’m only getting maximum of 450-500 Hz acquisition speed through the Teensy 4.1 at the highest rates, which is not sufficient for my intended application.

Has anyone had any luck interfacing the Magnetic Imaging Tile with more modern MCUs and achieving high frame rates? Any tricks to help achieve this? I’m using the demo code provided on the Sparkfun github:

Thank you!

Maybe try the max speed examples for SPI Teensy has https://github.com/tonton81/SPI_MSTransfer_T4 , then try to integrate that library with the V3 magnetic imaging one?
