hi Zitron,
I have a sure electronics accelerometer, and a rbbb, but missed the gyro on the list... which is the one you used, from the page linked to at r2hobbies? Right off, looking at your photo, I was confused by: the trim pot [is that the gyro?]; the connection between + and J2/sleep; and what appears to be an extra resistor off the bottom of the rbbb. I ask 'cause, as a noob, small errors repeat endlessly when guessing a build.  thanks, and cool work!  david

yikes, I have all these pieces, and would like to put them together! Could I ask you to post a schematic, or more detailed pictures of the build, so I can see your wiring... at a glance, it isn't all obvious to me.

and in very simple mode, here....
I would like to read text [no writing] from a txt file on an SDcard, and send it to an LCD using serial.print... I have looked high and low through all the examples, but being um noob, I am having a heck of time figuring out how to do that. Could someone hold my hand, e.g. a code example? I use a 4x20 display, and of course there are control characters. I imagine I have to format the text for half the screen then the other half, each new section on a new line in the text file, padding each line to proper length [since I can't figure out how to parse/split text]... I am also having some um conceptual problems on how to go from bytes -> ascii, but I guess that will just be obvious in the code example, for which I certainly and hopefully do thank you in advance! I hope.

here is the schematic again, from dfraser
