I think this would be very hard to do in real time. Your 3DH does have a FIFO buffer, but only a few samples worth. I doubt even the Cortex...

Oops - hit the enter key too soon. Figuring this out took me a long time. There are lots of examples for Arduino Unos and similar devices, but I didn't...

In my script I use a while statement to take a certain number of readings. I put the attachInterrupt statement just before the while. Then just after the closing }...

Hooked up the 3DH tonight and can confirm that all of the above works and that writing 0x10 to CTRL_REG3 sets up the interrupt on INT1 when data is ready.

Thanks. Also want to thank you for the DEBUG idea. Was getting ready to comment out lots of Serial.print statements to enable battery operation. Read up on how your DEBUG...

Would be interested to know how to set up another SPI. I don't think I2C is your primary bottleneck at this time, but every place you can find a uSecond...

No problem. I'm not ignoring this one, but the words aren't coming to me as easily as with the other subjects. I think now that the others are written down...

@erichiggins That's understood. I was thinking about all those things already so figured I might as well write it down. I do feel like at some point I committed myself...

My comments on buffering will likely have 3 parts, but I'm not sure I'll have time for all three this evening. 1. How I think the SD card works 2....

It seemed like the best way to illustrate the functioning of the circular buffer was to take a copy of your code and show what changes would have to be...
