Discovery kit with STM8S001J3M3,
STM8L001J3M3 and STM8L050J3M3 MCUs
Introduction
The STM8-SO8-DISCO helps to discover features of STM8S Value Line and STM8L Value
Line devices available in SO8 packages. This discovery kit offers three SO8 to DIL8
modules designed with STM8S001J3M3, STM8L001J3M3 and STM8L050J3M3
microcontrollers, and allows the user to easily develop and share applications. It includes an
on-board ST-LINK/V2 to debug and program any of the embedded STM8 microcontrollers,
or even an external target by means of a SWIM connector. The STM8-SO8-DISCO is
operated by simply plugging it into a PC through a standard USB Type-A to Micro-B cable.

Evaluation tools marked as ‘ES’ or ‘E’ are not yet qualified and therefore they are not ready
to be used as reference design or in production. Any consequences deriving from such
usage will not be at ST charge. In no event, ST will be liable for any customer usage of
these engineering sample tools as reference design or in production.

7.2 Embedded ST-LINK/V2
The ST-LINK/V2 programming and debugging tool is integrated on the STM8-SO8-DISCO
board.
The embedded ST-LINK/V2 can be used in 3 different ways:
Program/debug one on-board STM8 device by selecting it using the corresponding
solder bridges
Program/debug a STM8 device mounted on a DIL8 module plugged to the socket U3
Program/debug an external STM8 device mounted on a user application board using a
cable connected to SWIM connector (CN1)
The embedded ST-LINK/V2 supports only SWIM for STM8 devices. For information about
debugging and programming features refer to ST-LINK/V2 in-circuit debugger/programmer
for STM8 and STM32 User manual (UM1075), which describes in details all the ST-LINK/V2
features.
7.2.1 Using the ST-LINK/V2 to program/debug one on-board STM8 device
To program/debug one of the on-board STM8 device, solder bridges must be configured as
detailed in below table. In addition, no DIL8 module must be present on the socket U3 and
no external target must be connected to CN1.
Note: Practically, only SB1, SB4 and SB7 are used to redirect the SWIM signal to the selected
STM8 device. But to prevent conflict on GPIOs used for the user push-button and LED, it is
preferable to also configure others solder bridges.
7.2.2 Using the ST-LINK/V2 to program/debug a STM8 device on a DIL8
module
To program/debug a STM8 device mounted on a DIL8 module plugged to the socket U3, it is
required to set all solder bridges OFF (SB1 to SB9) and no external target must be
connected to CN1. The DIL8 socket pinout is detailedTable 3.

Note: When plugging the DIL8 module to the socket, please pay attention to the pin 1.
7.2.3 Using the ST-LINK/V2 to program/debug an external STM8 device
To program/debug an external STM8 device mounted on a user application, it is required to
set all solder bridges OFF (SB1 to SB9) and to remove any DIL8 module from the socket
U3.
The user application must be connected to the STM8-SO8-DISCO using the SWIM
connector (CN1).
Note: This program/debug connector is only 3.3 V compliant.
7.2.4 Driver
Before connecting the STM8-SO8-DISCO board to a Windows PC via USB, a driver for the
ST-LINK/V2 must be installed. It can be downloaded from the www.st.com website.
In case the STM8-SO8-DISCO board is connected to the PC before installing the driver, the
PC device manager may report the interface as ‘Unknown’.
To recover from this situation, after installing the dedicated driver, the association of the
‘Unknown’ USB device found on the STM8-SO8-DISCO board to this dedicated driver, must
be updated in the device manager manually.
7.2.5 ST-LINK/V2 firmware upgrade
The ST-LINK/V2 embeds a firmware upgrade mechanism for in-situ upgrade through the
USB port. As the firmware may evolve during the life time of the ST-LINK/V2 product (for
example new functionality, bug fixes, support for new microcontroller families), it is
recommended to visit www.st.com website before starting to use the STM8-SO8-DISCO
board and periodically, in order to stay up-to-date with the latest firmware version.

7.3 Power supply (CN3)
The STM8-SO8-DISCO is designed to be powered using the ST-LINK/V2 USB connector
CN3.
7.4 LEDs (LD1 and LD2)
The STM8-SO8-DISCO features a user LED (LD1) connected to the pin 5 of the DIL8
module. To light on this LED, a high logic state must be output on the corresponding STM8
GPIO.
The tricolor LED (green, orange, red) LD2 (COM) provides information about ST-LINK
communication status:
Slow blinking Red/Off: at power-on before USB initialization
Fast blinking Red/Off: after the first correct communication between the PC and
ST-LINK/V2 (enumeration)
Red LED On: when the initialization between the PC and ST-LINK/V2-1 is complete
Green LED On: after a successful target communication initialization
Blinking Red/Green: during communication with target
Green On: communication finished and successful
Orange On: Communication failure
7.5 Push-button (B1)
The STM8-SO8-DISCO offers a user push-button (B1) connected to pin 7 of the DIL8
module. To retrieve the push-button state, the firmware must read the corresponding STM8
GPIO.
The use of the push-button depends on the STM8 device firmware.

7.6 IDD measurement (JP1)
Jumper IDD (JP1) allows to measure the consumption of a STM8 device by removing the
jumper and by connecting an ammeter:
Jumper ON: STM8 device(s) is (are) powered (default).
Jumper OFF: an ammeter must be connected to measure the STM8 device(s) current.
If there is no ammeter, STM8 device(s) is (are) not powered.
Note: By default all STM8 devices are powered. To isolate the power consumption of only one
STM8 device, it is required to either cutout the non-required DIL8 modules or to cut all of
them and insert the required DIL8 module in the socket U3.
