I noticed that even after hardcoding pin 25 in Sd2Card.cpp, that pin 31 on my Olimexino was still being used by the SPI. So I did those nssPin() changes you suggested. I was then sorely tempted to lazily modify wirish/boards/maple.h and change 31 to 25 there---after all, my Olimexino has behaved EXACTLY like a true maple up until now---but then decided to make a brand new board type called "olimexino" (which involved updating numerous other make-related files). But now it's done right. Kinda cool seeing that olimexino.elf file! feurig on "SDFAT Help with MAPLE CLONE" http://forums.leaflabs.com/topic.php?id=1549#post-11169 Fri, 08 Jun 2012 14:49:33 +0000 feurig 11169@http://forums.leaflabs.com/ <a href="http://code.google.com/p/maple-sdfat/issues/detail?id=2" rel="nofollow">http://code.google.com/p/maple-sdfat/issues/detail?id=2</a> dugggg on "SDFAT Help with MAPLE CLONE" http://forums.leaflabs.com/topic.php?id=1549#post-11166 Fri, 08 Jun 2012 12:48:23 +0000 dugggg 11166@http://forums.leaflabs.com/ In addition to the two changes to digitalWrite, you also have to change the pinMode(10) line to pinMode(25) in Sd2Card.cpp for the Olimexino. bubulindo on "SDFAT Help with MAPLE CLONE" http://forums.leaflabs.com/topic.php?id=1549#post-10214 Sun, 15 Apr 2012 21:40:36 +0000 bubulindo 10214@http://forums.leaflabs.com/ I had a look before and I don't think the library has it. However, it's still a work in progress. I think that whoever was developing it in the beginning just left it at the bare minimum. There's no interrupt controlled SPI, but then again with the DMA possibility I'm not too sure one would want to have interrupt controlled transmission and it was left for future implementation. feurig on "SDFAT Help with MAPLE CLONE" http://forums.leaflabs.com/topic.php?id=1549#post-10213 Sun, 15 Apr 2012 19:44:18 +0000 feurig 10213@http://forums.leaflabs.com/ bubulindo, Is 25 also what the spi nss pin is for your maple derivative? If so it makes more sense to use SPIn->nssPin(), Either way the library should probably have a way to set the select pin on init instead of hardcoding the pin in the chip select in the chipSelect routines. This is legacy bad coding from the original arduino library and should be fixed. <a href="http://code.google.com/p/maple-sdfat/issues/detail?id=2" rel="nofollow">http://code.google.com/p/maple-sdfat/issues/detail?id=2</a> Does anyone know how to get the bugs fixed in the library github since there are at least 4 threads now regarding issues with it? bubulindo on "SDFAT Help with MAPLE CLONE" http://forums.leaflabs.com/topic.php?id=1549#post-10204 Fri, 13 Apr 2012 17:59:50 +0000 bubulindo 10204@http://forums.leaflabs.com/ I'm in Southeast Asia now and just got in my office (7 AM). I have all my Maple stuff in my computer at the hotel, the best I can do is to put that through to you when I arrive there in about 10 hours or so. :\ Also, I ran these examples outside the IDE. I installed the libmaple and compiled from there. Maybe this has something to do with it? Either way, I can forward both folders to you. Good enough?

I bought the cheapest I found at the time (running the risk it wouldn't work). I looked at it now and it's 8Gb. The 1 and 2 Gb cards are way to expensive these days. Come to think of it, I think I had to change the CS pin. In file Sd2Card.cpp my pin is 25. <pre><code>//------------------------------------------------------------------------------ void Sd2Card::chipSelectHigh(void) { digitalWrite(25, HIGH); } //------------------------------------------------------------------------------ void Sd2Card::chipSelectLow(void) { digitalWrite(25, LOW); }</code></pre> Is that what you have in your library? robarino on "SDFAT Help with MAPLE CLONE" http://forums.leaflabs.com/topic.php?id=1549#post-10188 Fri, 13 Apr 2012 02:27:15 +0000 robarino 10188@http://forums.leaflabs.com/ Hej Bubulindo!

I hope I am not stepping on anyones toes asking about the Olimexino and SDFAT library. I have tries to install the library (there are two...which one is it?). I have tried both of the libraries there and I have had no luck running and saving. The "sys" éxample compiles and I get a blank screen on the serial I was wondering if anyone has it working on the Olimexino? If so maybe you could zip your maple IDE and throw it in a dropbox for me? Or let me know how you got it working. I will give you a big Tack så mycket if you can help me out!
