Excellent work guys:-) I'm trying to make a project on stm32f103re, trying to capture hand motion, I'm comfortable with accelerometers and gyros, relatively new to stm32. How difficult would it be to remap the pins and ports to add my board configuration in Maple IDE? </p> <p>Thank you </p> http://forums.leaflabs.com/topic.php?id=70#post-4857 Fri, 27 May 2011 18:13:11 +0000 Mars Saxman 4857@http://forums.leaflabs.com/ <p>Thanks for the info, gbulmer.</p> <p>I have had great results with the ROM bootloader on the STM32 chips, so that is what I am planning to use on the Olimex board. </p> <p>I never had any luck with dfu-util. I can program the Maple board using the Maple IDE but can't program it from the command line; it just doesn't go, and I've had no luck figuring out why. The project I'm working on is painfully large for the Maple IDE so I'm looking for a way to break out and use a normal compile environment. I'd also like this gadget to use its USB interface as a MIDI device, which appears to be difficult with Maple; so I think I might be happier with this Olimex board. Still, libmaple makes life a lot easier, so I'd like to stick with that. </p> http://forums.leaflabs.com/topic.php?id=70#post-4724 Mon, 23 May 2011 14:14:25 +0000 gbulmer 4724@http://forums.leaflabs.com/ <p>Mars Saxman -</p> <blockquote><p>I just picked up an Olimex STM-H103 board, available on Sparkfun.

If you check out the latest version of libmaple from our github repo, setting MAPLE_TARGET=jtag and simply typing 'make' will generate a .bin file in build/ that is suitable for any stm32f103rb or similar chip. You can upload that .bin over the serial bootloader, or jtag, or whatever solution you'd like on other boards.</p> <p>I also noticed your post (I think it's you?) on the stm32 forums looking for W5100 code. I messed around with it briefly a few weeks ago and posted some development code to a branch on our github repository. It's a little out of date and I haven't gone through and made it presentable for people to use, but it does correctly bring up the chip over SPI and bring up a basic webserver.</p> <p>Feel free to look at it if it helps:<br /> <a href="http://github.com/leaflabs/libmaple/tree/ethernet-shield" rel="nofollow">http://github.com/leaflabs/libmaple/tree/ethernet-shield</a> </p> http://forums.leaflabs.com/topic.php?id=70#post-354 Fri, 25 Jun 2010 15:01:14 +0000 bnewbold 354@http://forums.leaflabs.com/ <p>Hi Thomas! Anything is possible! </p> <p>It's definitely possible to use our toolchain with non-Maple stm32 chips without too much pain. It's kind of a hassle to extract the .bin files generated by the IDE because the arduino compilation process uses random temporary directories. If you really want to use the IDE you could modify it with a new "board type" and/or a different upload mechanism (see "DFUUploader.java" and try not to vomit on the keyboard). Or you could use Code::Blocks or similar: <a href="http://leaflabs.com/docs/libmaple/unix-toolchain/" rel="nofollow">http://leaflabs.com/docs/libmaple/unix-toolchain/</a></p> <p>I'm a little unclear what you mean by "the USB DFU Linker"; do you mean the dfu-util uploader? The linking stage of usercode compilation doesn't have anything to do with DFU.</p> <p>I really like the projects on your blog! Especially the mini-oscilloscope, I might re-implement something like that with libmaple... </p>
