Write data to SD card with RFduino
« on: May 06, 2017, 07:07:02 PM »
Are there any examples of high frequency data logging to SD card with RFduino (> 100Hz)? I need to be able to write in multiple blocks. Any suggestion are appreciated.

I have been trying using SdFat library, but it's not compatible with RFduino (there are compilation error, which I think that SPI.h from RFduino does not fit with Sdfat). Any way to fix this?


UPDATE:

I managed to make SD library work with RFduino (Arduino 1.6.5, RFduino 2.3.2 and some old version of SD library from arduino 1.5.6). However I still need to use Sdfat library to reduce number of IOs.

What is the difference between libraries

inside Arduino.app: Arduino.app/Contents/Java/libraries;

/Arduino15/packages/RFduino/hardware/RFduino/2.3.2/libraries

and Documents/Arduino/libraries?
