My impression of the SPL is quite mixed. It seems much more complicated than e. Wiring for Arduino. And for the latter with x registers, a standard HW-lib is almost mandatory. We use optional third-party analytics cookies to understand how you use GitHub.

If you are interested in knowing how, you can follow the links below. Without a doubt, the Arduino IDE is great for beginners, but still, for professional development, it is good to work with native development environments and compilers. Using the native platform allows us to work on register level even assembly level if required enabling the program to be more memory effective.

This increases the compiling and uploading time and makes development and debugging a pain. I went in search of alternatives and that is when the Arduino IDE came for rescue.

A tool called Sduino by Michael Mayor allows us to easily program the STM8s Microcontrollers most of the popular ones from the Arduino IDE directly and it only takes minutes to set this up and get started. Although the Sduino is a cool tool, it is still in development and is yet to support many of the Arduino libraries and functions.

If you are completely new to this board, then do check the getting started with the STM8SF tutorial. The procedure explained in this tutorial is the same for all.

Step 1: If you are completely new to the Arduino Environment, Download Arduino based on your operating system and install it. Click on install and close the dialog box after the installation is completed. You can select other boards if you have a different development board. Let us set up the board, connect it to the computer, and program for a simple LED blink.

The connections are pretty straight forward and the best part is you need no external components. My hardware setup for programming is shown below, I have just used the female header wires to make my connection. However, do note that the pinout of your ST-Link might differ from mine, make sure to follow the pinout on the device before making the connections. Make the connection and connect the device to your computer, the driver installation should begin automatically.

You will also notice the test LED on the board blinking if this is the first time powering the board. Now for a simple LED blinking, we can use the blink program from the example section. As you can see this is very similar to the Arduino blink program. Note : Unlike Arduino boards, you do not have to select the right COM port for programming the board.

You will use the COM port only for serial communication. Once the COM port is selected, uploading the code is also very simple.

Just press the upload button encircled in red below and the code will get compiled and uploaded to our board automatically. That is it, the program is uploaded directly to the board and you should see the on-board LED blinking.Now user Kenjutsu suggested to link the STM8 board of this forum from my project website as a place for general discussions about my project. I hope that is ok? I would love to integrate it into the IDE. If somebody would find a way to make it work with C only would be great!

Right now I am using a Makefile based on the Arduino. That works great on Linux and MacOS and is my favorite working style, but unfortunately, windows is not suited very well for this and things get slow there. Really slow. This happens because make heavenly relies on forking the current process which is not supported on Windows and is internally emulated by starting new processes from scratch.

And that takes time. A lot of time. Compiling-the-blink-example-takesseconds kind of time.

Time wasted just to needlessly starting and killing subprocesses. I guess this is why the Arduino guys came up with their proprietary build system in the first place.

Somebody came up with a python implementation of a simple build system. That might be an improvement, but using the stock Arduino one would be the best. RogerClark Thu Oct 12, am tenbaht. The overhead is about 2kb using IAR. It may be helpful if you look into your code and see which functions are taking up the most space and gradually replace them with your own code to save space.

Yes, the SPL is a memory hog and quite complicated to use. The only advantage I can see in using it would be to be prepared for an easier migration to the STM To avoid the 2kB penalty of linking dead code I wrote a Makefile that breaks up the SPL source files into single-function source files and compiles them separately.

This way only the functions that are actually used get linked into the project and no dead code is left. The code size still seems to be bigger than with the commercial compilers, but I never investigated in detail how big the difference really is.

I really love the very direct access to the inner workings of the compilation stages, especially the extremely useful assembler listings. That is much better than for any other compiler I have used so far. It should just work — the same way it does for the regular Arduino libs.

In summary. Unfortunately these are mutually incompatible, so code snippets need to be fixed manually This may be ok for experienced users but is probably a no-go for newbies. Independent of the above items there are at least 3 more activities ongoing which IMHO require to solve the legal issue once and for all:.

Michael Mayer recently released a tool to split the SPL functions into separate files :. This significantly increases SPL attractiveness. Aim is to make STM8 programming equally easy as Arduino. Currently sduino uses the patched SPL headers. I feel there exists no synchronized discussion with STM to solve this topic once and for all.

Please correct me if I'm wrong!? Looking forward to a lively discussion! Note: a similar issue exists for my serial upload tool stm8gal see issue 4. If possible, I would like to avoid inventing the wheel again, just to remove a few bytes of "non-free binary blobs" So basically, a well established proprietary library is the only thing that discourages companies from using the cheaper clones. And because people at St know that they have a valid point and because they are not dumb, they are not going to move.

Well, we can write our own interoperable header. There are projects like wine, after all.

We can basically rewrite every macro or typedef that is trivially derived from the datasheets in exactly the same way.

Anything else can still use the same interface i.

For example, while St's headers use bit masks, AVR headers use bit numbers. We could therefore define macros for bit numbers within a register and then base the St-compatible mask macros on those. This would have the additional advantage of simplifying porting efforts even further. The best approach with SDCC in mind would probably be one monolithic header with typedefs and macros, only.
