The basic CN0540/DE-10 setup is working and I'm able to capture data from the ADXL1002 accelerometer. However, any filter setting changes I make using the DE-10 GUI does not seem to take effect. I have been able to scope the CN0540 (attached to the DE-10) for the SPI signals when reading the register values and it looks good. However, for some reason I'm unable to write to the register again. The command goes through; and the scope shows the write command on the SPI lines. But when I read the register after the write, it still has the default value and it hasn't taken the new value I wrote. Note that I am able to successfully write and then read back the new value to the registers when I use the Teensy to interface with the CN0540 instead of the DE-10.
