I am working on a project that requires sampling 32bit data at 30kHz on 64 channels. Currently, I am only able to push the sampling rate to be at 7.4kHz. Teensy4.1 is overclocked to 960 MHz and the SPI ckockin is 21M. Is there a way to feasibly achieve the desired sampling rate? Open to adding on a separate SPI driver if necessary but would appreciate suggestions.
