1. Connect the STM8SVLDISCOVERY to a PC with a USB cable.
2. Press the B1 button, and observe LED LD1 blinking.
3. Press the B1 button to change blinking speed.
4. Visit www.st.com/stm8svldiscovery and follow the tutorial, then discover other
applications.
You can discover more of the STM8S features by downloading and executing the proposed
programs in the project list.
Note: The software code corresponding to this application is available under the name Discover
(AN3996) in the project list of the STM8SVLDISCOVERY web page.

2 Hardware and layout
The STM8SVLDISCOVERY is designed around the STM8S003K3T6 microcontroller in an
LQFP32 package. It has two distinct sections that may be separated, the STM8S003K3T6
module and the ST-LINK module.
Figure 2 illustrates the connections between the STM8S003K3T6 and its peripherals (ST-
LINK, user button, LED and connectors).
Figure 3 helps you to locate these features on the STM8SVLDISCOVERY board, as well as
the potential point of separation (for more details refer to Section 2.2.2: Using the ST-LINK
on other STM8S applications).

2.2 ST-LINK
The ST-LINK provides a USB interface for programming and debugging using a single wire
interface module (SWIM). The ST-LINK module of the STM8SVLDISCOVERY also supplies
5 V and 3.3 V to the STM8S003K3T6 module.
2.2.1 Using the ST-LINK
Figure 6. Typical configuration
Note: The driver for ST-LINK is installed automatically when the USB is connected.
For information about debugging and programming features refer to ST-LINK, STVD, STVP
and SWIM on www.st.com.
2.2.2 Using the ST-LINK on other STM8S applications
You can connect your ST-LINK to other STM8S applications in 2 ways:
By removing the solder bridges: This way uses the ST-LINK without breaking the PCB.
Unsolder the two solder bridges SB1 and SB2 under the SWIM connector.
See Figure 7. You can re-solder the two bridges at a later date thus keeping the
STM8SVLDISCOVERY usable.
By breaking the board and removing the ST-LINK: This way constitutes a good
alternative to programming the STM8S devices in other applications. See Figure 8.
Note: This ST-LINK only supports the STM8S family. Do not use it with other STM8 families.

Warning: By removing this module you will lose power supply on the
STM8S003K3T6 evaluation board. Consequently, you will
need a SWIM cable and an external power supply to program
and use the STM8S003K3T6 board.
To reconnect your STM8S003K3T6 use connector CN7 see
