Please correct my terminology, as I said I am brand new to FPGA boards so here goes: I was planning to use the ZAP interface, which as far as I can tell means I would load a pre-made bit file, which basically spoofs an Arduino at a possible faster clock speed and with more IO ports (the main reason I chose the Papilio One over the Arduino Uno; all around more flexibility it seemed). Does this make this issue better (there already exists an Arduino lib for all of the accels on Adafruit)? Does it still warrant preferring a different accelerometer?. From what I understand after some brief reading is that I2C differs from SPI in that I would have to do some minor parsing of the stream to get the output using I2C (searching for packet starts and logging them; filtering the input channel), whereas SPI is already direct output. I don't mind springing for a more straight forward card but would want to move to the 2021, because the added magnetometer will give me a global coordinate system frame (I can use for added autonomy later... maybe).
