I would like to use the Adafruit data log with my Chipkit 32 Uno

I have the data logger and it is working good on the Arduino Uno (both SD and RTC) (using the Adafruit supplied libraries)

I would like to use the Chipkit 32 Uno processor board and have a couple of questions.

1. SD Library - Should I modify and use the Adafruit provided SD library or the standard SD library supplied by chip kit ???

2. Is there a hardware issue between the data logger and Chipkit 32 ? I have seem some forum posting but not sure is there is a problem or has it been resolved Do I need to modify the data logger hardware to be compatible with the 3.3 volt chip kit 32

Thank BrianD

You will have to use the SD library bundled with MPIDE.

You will need a DS1307 library that works with the chipKIT - the Adafruit one may work, or it may not - the biggest issue is whether they have written it to work with the 0023 version of the Wire.h library, or if it's limited to the 1.0.x version only. Try it and see.

The level shifter (74HC4050) may well be getting in the way of the SD card, so you may need to remove that and bypass it, or it may work fine - it depends somewhat on your SD card and how Adafruit have chosen to wire it up. Try it and see.
