Support for other STM32 Boards?

Hi Leaflabs.
I just passed by your site when searching for different STM32 boards on the internet.
I'm an advanced STM32 user who have done many projects with different STM32 boards - also some made by myself.
Please check out my blog for more information about my projects: http://elec.tkjweb.dk

Anyways, my question is if it's possible to compile the code using your IDE but without having to use your USB bootloader (the code should be placed in the FLASH BASE and it shouldn't use the USB DFU Linker!
Is this possible?

Best Regards
Thomas Jespersen

yes! if youre in libmaple checked out from github, i believe the command is:
$ make jtag

if youre using the olimex JTAG with openocd you can continue with
$ make program_jtag

Either way, libmaple is in no way dependent on the maple bootloader, the maple itself, or DFU. It is a meant to be useful on its own as a library for the stm32 line. Right now, parts of libmaple are somewhat tailored to the stm32f103 part we use on maple, but were working on making it more generic. We have two new boards coming out that use different stm32's, and so libmaple is getting a lesson in portability.

Hi Thomas! Anything is possible!

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: http://leaflabs.com/docs/libmaple/unix-toolchain/

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.

I really like the projects on your blog! Especially the mini-oscilloscope, I might re-implement something like that with libmaple...

hey thomas,

I just checked in a different build system for libmaple, so the 'make jtag' target no longer works. 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.

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.

Feel free to look at it if it helps:

I will take a look at that ethernet shield code for Maple - it would be easy to "extract" the generic C code from it, to use in my own project, which is made in Ride 7.

bnewbold: I will be more than happy to help with this great project - send me an email at tkjmail@gmail.com

I'm currently working on porting Arduino to a mini-STM32 board:
http://www.micro4you.com/store/Mini-STM32-STM32F103-TFT-LCD-Board/prod_129.html

I've added a section to the "boards.h" file for the mini-STM32 (as per header instructions). I just need to test now.

The board has temperature, additional 2Mb flash, and a 2.8" LCD with touchscreen. This should keep me busy developing for a while....

that looks a slick devboard. do you know what the max framerate is to the LCD/the interface? (I assume its an 8 bit data parallel + ctrl lines or perhaps SPI)

It's a 16 bit interface to the LCD + ctrl pins, so I'm presuming it has decent framerate. There's a youtube video of it analysing a signal:

One other thing about porting this board to Aruduino. In the "boards.h" file, I'm listing the pins in the sequence that they appear on the mini-STM32 board. So basically I'm reordering the pins from the "BOARD_maple".
Is this a good idea? I'm trying the weigh up the pros and cons of doing it this way rather than perhaps keeping the pin numbering the same as the Maple with the idea that some of the examples may be easier to run (I won't have to go thru changing pin numbers). Any thoughts?

Looks nice :-) Also a very good example of aliasing ;-)

I just picked up an Olimex STM-H103 board, available on Sparkfun. Looks pretty similar in fundamentals to the Maple board, but with a different form factor. Anyone tried running libmaple on one of these?

No, but we did have a thread about the Olimex STM32-P107: http://forums.leaflabs.com/topic.php?id=738

Mars Saxman -

No I have not.

Obviously, the pin map for Maple won't match the Olimex board, but I assume you understand that.

I had a quick look at the schematics, and it is very slightly different from Maple, so I don't believe Maples USB bootloader will work without a bit of software effort because the USB 'signalling' ('DISC' disconnect) pin is different.

The user controlled LED is on a different pin. libmaple uses that LED to signal errors, so that would be worth fixing, as the board will look like it is dead otherwise. The pin is free on the Olimex, so just add an LED+Resistor to pin 21.
The boot control pins have solder bridges on the Olimex to select which boot 'partition to use', Maple uses a button, and one signal is 'hard wired'. Also on Maple the buttons are connected to a couple of signals, so 'BUT' won't work out of the packet on the Olimex in the same way.

There is a component (U2) on the Olimex which may not matter (its componentvalue is NA). If it is fitted, it is connected to the RESET signal, but I don't understand what it does (if anything), but I think that that only matters during reset anyway, so I don't believe it is a show-stopper.

Assuming none of that is an issue, the processors are the same, so the code won't know it isn't running on Maple.

How do you plan to load code onto the Olimex?

Thanks for the info, gbulmer.

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.

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.

Hi Leaflabs,

Maple IDE looks wonderfully simple tool to operate... 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?

Thank you

For head start I found this pretty useful...

http://forums.leaflabs.com/topic.php?id=105

I'll further look into all the blogs first...
Any more help would be really helpful :-)

Thank you
