I have SPI and I2C eeproms here with me.</p> <p>I've ported XBee library and it's working on API Mode(wonderful). My RFID readers is working fine too, so my 3 UARTs are fine.</p> <p>Everything is working but I can't make a RFID Card database(anywhere). Of course I can put the database on my house's server but and if my server crashs? and what's the fun on that? :)</p> <p>I2C EEPROM is an option but I'm facing maple hanging(I have other thread).</p> <p>So, I bought an arduino mega2560. Everything are working there. Just works.</p> <p>Maple mini is cheaper and is a very better microcontroller. I'm just not having luck(or coding skills) to resolve my problems. </p> http://forums.leaflabs.com/topic.php?id=909#post-5626 Tue, 12 Jul 2011 12:10:49 +0000 mbolivar 5626@http://forums.leaflabs.com/ <p>I took a look; it wouldn't be hard to update the library for use with the latest libmaple. I'd say the easiest way to go about it would be:</p> <p>- Move eeprom_25xxx.c to eeprom_25xxx.cpp, and delete the relevant #ifdef __cplusplus bits (from eeprom_25xxx.h). (Wirish used to be a mixed C/C++ library, but it's been C++ only since the refactor).</p> <p>- Convert spiNum (or spi_num, whatever) to pointers to a struct spi_dev instead.</p> <p>- Update the calls to spi_foo() in eeprom_25xxx.cpp to use the new SPI API, which is documented here: <a href="http://leaflabs.com/docs/libmaple/api/spi.html" rel="nofollow">http://leaflabs.com/docs/libmaple/api/spi.html</a></p> <p>This would actually be a very good exercise for anyone who's interested in learning a little bit more about the low-level C layers of libmaple. The necessary changes are few and straightforward. I'd recommend reading the libmaple overview if you're just getting started; it explains the overall library structure, its naming conventions, etc.:</p> <p><a href="http://leaflabs.com/docs/libmaple/overview.html" rel="nofollow">http://leaflabs.com/docs/libmaple/overview.html</a></p> <p>When 0.0.10 came out, we promised that the new libmaple APIs would be stable for the foreseeable future, and any removals from the API would go through a deprecation period first. So updating this library wouldn't be something you'd have to keep doing; it'd be stable for as far out as we can see right now.</p> <p>Edit: You can even use HardwareSPI as an example for how to use the new spi.h:</p> <p><a href="https://github.com/leaflabs/libmaple/blob/0.0.11/wirish/comm/HardwareSPI.cpp" rel="nofollow">https://github.com/leaflabs/libmaple/blob/0.0.11/wirish/comm/HardwareSPI.cpp</a> </p> http://forums.leaflabs.com/topic.php?id=909#post-5621 Tue, 12 Jul 2011 05:48:02 +0000 robodude666 5621@http://forums.leaflabs.com/ <p>You can simply checkout/download the entire <a href="https://github.com/adamfeuer/libmaple/tree/eeprom_25xxx">eeprom_25xxx</a> branch adamfeuer has on github. The EEPROM25xxx library is just a small library within that branch. I imagine that older branch should compile just fine with that library. </p> http://forums.leaflabs.com/topic.php?id=909#post-5619 Mon, 11 Jul 2011 16:52:06 +0000 trunet 5619@http://forums.leaflabs.com/ <p>could you tell me what's the last working git tag before SPI refactor? </p> http://forums.leaflabs.com/topic.php?id=909#post-5618 Mon, 11 Jul 2011 14:58:10 +0000 robodude666 5618@http://forums.leaflabs.com/ <p>The <a href="http://wiki.leaflabs.com/index.php?title=SPI_EEPROM_Library">SPI 25xxx-series EEPROM</a> library was written for an earlier version of libmaple, before the SPI refactor, and therefore will no longer work as-is.
