Data Logging with Flora

[cheshmat1]

Hello,

I was curious to know if there was a simple way to write data to a USB drive or SD card from a Flora? I'm trying to log pressure sensor data that is continuously being read by Flora.

Hope you can help, thanks!

You can use an SD card.. that's easy. We have breakouts that will hold the card and a software library that will handle everything.

Using a USB drive would be hard. The Flora's microcontroller is capable of acting as a USB master, but none of the existing code supports it. You'd pretty much have to start from scratch.

Hi Mike,

Just to clarify, I am able to use https://www.adafruit.com/products/254 to interface directly with Flora and write to an SD card with just the break out board and Flora? Right now I was under the impression that I would need https://learn.adafruit.com/adafruit-data-logger-shield/ and an Arduino to do this.

Let me know, thanks!

The shield contains an SD card interface (essentially the same circuitry as on the #254 micro-SD breakout) and a DS1307 Real-Time Clock.

If you want time-stamps in your log, then you can use the shield, or the #254 plus the #264 Real Time Clock breakout.

However, there is an incompatibility between the 3.3v Flora and the 5v DS1307. You will need a level shifter in between

This would apply to the shield as well as the breakout.
