ST IDE/compiler chain for STM8S works perfectly with Virtual Box/XP instance under Ubuntu Maverick.

St-Link debgger JTAG.

Spent day off today downloading the tool chain for this board, got one off Mouser, kind off a rip for shipping and tax take this to 20$… however shipping same day so good service, still good deal I think.

IDE looks very strong, lic. for 32k compiler took less than hour to receive. Debugger is very strong inside IDE, steps like a dream.

Nice simple libs for peripherals, clean coding style well commented.

This chip/board is a sleeper. Peripheral on cpu bus are kind of whimsical. Beep register for example… looks like fun!

Hello all,

Happy new year 2011 first :-).

If you are interested in dedicated ultra ow power microcontrollers go to check my new web site. This one is deditaced for ultra low power STMicro, TI & Microchip^. Feel free to comment.

Thanks Miroslav. If some has already played with it I will be very interrested to get some exemples.

Thanks a lot & have a nice day.

@Nakim, not only Low Power, but comes with LCD on the board. One can find it for arround $10 at “standard” retalers :)

Got it the other day, still in a blister package, can’t find time to play with it

Hello Guys,
Does anyone tryed the STM8L-Discovery ? This is the Ultra low power version of this kit.

Thanks a lot.
Nakim.

Sorry, I have absoultely no interest in trying one of these after reading all of the negative reviews. They better get their stuff together for future releases is all I can say.

hi,
i have some questions about TSL for the stm8s discovery.
i have made a layout for a wheel with 8 electrodes and now i want to use it with the touch sensing library.
in the tsl config i introduced the mckey with 8 channels.
so far all right.
now i don’t know how i have to introduce my wheel in the main.c data.
firstly i just want set the led when i touch a position at the wheel but i don’t really know how.
i hope you can help me perhaps somebody has a example for a wheel used with stm8s controller.
thank you in advance

Hi,
I have downloaded the 32k compiler, the licence I´ve got after 3 minutes. The STM8S Kit is ordered.

Hello iDave,

look at the website of Cosmic. http://www.cosmicsoftware.com

They offer a free compiler up to 32K as a special offer in March 2010.

Concerning the Linux support ST is currently trying to identify a way of how to let open source developers have access to the debugger protocol specification (1st contacts made during the embedded world show).

Maybe there will be some native Linux support soon.

Greetings

Anyone have an idea when the compiler will be expanded to 32k? Will it happen?

On the subject of development under Linux, I can confirm that USB communication does work if you run Windows in VirtualBox. You need to ensure you are using the USB-capable version of VirtualBox, and set up a filter for the USB device within the VM’s settings. It’s not ideal but it’s a solution that might be appropriate for some people while native tools do not exist.

He, he,

pretty much animated discussion here. But seriously, this STM8 micro is really fast. Further up I read someone stating it was X86 modified core, but that’s kinda wrong. The STM8 core seems more like an improved ST7 core (also from ST) which was basically an HC05 core.

But the STM8 is really a speedboat. At 16MHz undivided clock, it takes average 1.6 cycles per instruction. And the instruction table has been reviewed drastically. The instructions that are most used in C-compilers are now the shortest ones. That gives you a significant thrust and the code is also smaller. Try to hand-code something more efficient as the C-compiler for STM8 delivers and then compare with the HCS08 for instance. You’ll see …

And now they even start to distribute those kits for free on shows.

Check this out:

If this becomes a habit and as Pat says the 32K Compiler version will be for free in the future ?

Who will then pay for any development tool ?

Cheers

@Patrice,

I was referring to other microcontrollers providers full evaluation boards cost, just to make a comparison like picdem 4.
