I would love to have this added as well

[bergernetch]

Would be great as there now is an ESP board with an STM8: ESP-14

[jourjine]

+1, please add support for stm8L family

[javigf]

+2, please add support for stm8L family

Not yet in Platformio??

[kissste]

nope

[xorbit]

In the mean time, there's this: https://stm8-binutils-gdb.sourceforge.io/ It seems to work well, and maybe Platform.io can use it as a base for integration?

As I see STM8 supported by SDCC - Small Device C Compiler https://www.fischl.de/stm8/stm8svl_discovery_linux/

[Khelicon]

+1 for STM8L

[DrNorfolk]

I will be glad to see support of STM8!

Folks, do you have any board from this list https://github.com/tenbaht/sduino/blob/development/sduino/hardware/sduino/stm8/boards.txt ?

[Gei0r]

I have one of those extremely cheap STM8S103 breakout boards, which I guess is called stm8sblue in your link. Although my board has an STM8S103F2, which only has 4 KiB of Flash.

I'll be willing and able to help implementing and testing.

1. Please open PlatformIO IDE Terminal and type

   pio platform install https://github.com/platformio/platform-ststm8.git

2. Restart VSCode and create a new project using PlatformIO IDE > PIO Home > New Project

Does it work?

[Gei0r]

I'm not using VS Code, I'm running platformio directly from the command line (plain cmd on Win10).

Compiling works.

But when uploading, the following error occurs:

Configuring upload protocol...
AVAILABLE: serial
CURRENT: upload_protocol = serial
Looking for upload port...
Error: Please specify `upload_port` for environment or use global `--upload-port` option.
For some development platforms it can be a USB flash drive (i.e. /media/<user>/<device name>)
*** [upload] Explicit exit, status 1

Upload command should be:

stm8flash.exe -cstlinkv2 -pstm8s103f2 -s flash -w .pioenvs\blue\firmware.ihx

However, this command mysteriously only works about 10 % of the time. But that might be some bad wiring, I'll keep investigating. Edit: As I suspected, this was because of very shoddy dupont wires that came with my stlink.

I now tried VS Code. Same problem with the upload tool.

Another problem is that when creating a new project, a main.cpp file is automatically created, which confuses the build system (SDCC is only a C compiler):

Compiling .pioenvs\stm8sblue\FrameworkArduino\WInterrupts.c.rel

It works when the main.cpp is manually renamed to main.c.
