ST Visual Develop (STVD) supports STM8 assembly projects through ST’s Assembler-Linker, so you can write, assemble, build, debug, and program STM8 code in one development environment. The practical sequence is to install the ST toolchain, identify the exact MCU on your board, consult the matching CPU and device manuals, then follow that board’s programming and debugging instructions.
What STVD does for an STM8 assembly project
ST describes STVD as an environment for building and debugging applications and programming microcontrollers. It integrates STM8 C and assembly toolchains, including the ST Assembler-Linker. ST lists its MCU toolset as a free download; check the STVD-STM8 product page for current availability and details.
For a beginner focused on assembly, the ST Assembler-Linker is the direct route. ST’s documentation index lists the STVD user manual UM0036, the ST Assembler-Linker user manual UM0144, and release notes for STVD 4.3.12 and Assembler-Linker ASM 4.52. Those are documented release references, not a guarantee that every download page currently offers those versions. Check the STM8 software development tools documentation index before installing, and use the manuals that match the versions you obtain.
Choose the exact MCU and its documentation
STM8 is a family, not a single chip. Before writing code or following a board tutorial, read the MCU marking or board documentation and record the exact part number and board revision. Instruction behavior belongs to the CPU documentation; peripheral addresses, registers, and device-specific behavior require the relevant MCU documentation.
#1 Best Overall
- Use STM8S103F3P6 as the master IC
- Support SWIM debug mode
- CPU and instruction set: Use PM0044, the STM8 CPU programming manual, for programming concepts and instruction reference.
- STM8S/STM8AF peripherals: RM0016 is the family reference manual for peripheral and register behavior. Confirm that it covers your exact device.
- Specific chip: Check the target MCU’s datasheet and errata for device-specific details and corrections.
ST’s STM8S series documentation index links to PM0044 and RM0016. Do not assume an example for one STM8 part has the same peripheral map or board wiring as another.
Install the toolchain and start a project
- Get STVD and the assembler-linker. Start at ST’s STVD-STM8 page, then check the documentation index for matching manuals and release notes.
- Read the installation and project guidance. Use UM0036 for STVD and UM0144 for the ST Assembler-Linker. Their project and command details are more reliable than instructions written for a different release.
- Select the exact target device. Configure the project for the MCU fitted to your board, not simply a chip with a similar family name. Consult its datasheet and errata alongside PM0044 and the applicable reference manual.
- Write and assemble the program. Use the assembler syntax and project configuration documented for the installed ST Assembler-Linker. Build the project and address reported errors before attempting to program the chip.
- Connect, debug, and program using board-specific instructions. Follow the board manual for the supported debug/programming interface and connection procedure. Confirm that your programmer or debugger supports the exact MCU and board setup.
STVD’s programming interface is based on ST Visual Programmer (STVP) and supports devices and programming tools supported by STVP. That does not make every programmer compatible with every STM8 board: check the target device and the tool’s support before relying on a particular setup.

Use STM8S-DISCOVERY as a documented example
STM8S-DISCOVERY is a concrete STM8 development-board example with ST documentation, including UM0834, titled “Developing and debugging your STM8S-DISCOVERY application code.” Start with the STM8 MCU evaluation board documentation index and the UM0834 manual.
Use UM0834 only when its board and target match the hardware in front of you. Board revision and MCU identity matter for wiring, available peripherals, and programming/debugging instructions. If buying a board or debugger, check the listing against the manual and verify what programming interface is included; current stock and listing contents can vary.

When to consider another assembler toolchain
Cosmic offers an STM8 toolchain with assembler support and states that it integrates with STVD. It is an optional alternative, not a prerequisite for an assembly project. Its current availability and licensing terms should be confirmed with Cosmic’s STM8 tools page. For a beginner looking for the direct ST-supported assembly path, begin with the ST Assembler-Linker.
