STLINK-V3SET debugger/programmer for STM8 and STM32
Introduction
The STLINK-V3SET is a stand-alone modular debugging and programming probe for the
STM8 and STM32 microcontrollers. This product is composed of the main module and the
complementary adapter board. It supports the SWIM and JTAG/SWD interfaces for the
communication with any STM8 or STM32 microcontroller located on an application board.
The STLINK-V3SET provides a Virtual COM port interface allowing the host PC to
communicate with the target microcontroller through one UART. It also provides bridge
interfaces to several communication protocols allowing, for instance, the programming of
the target through the bootloader.
The STLINK-V3SET can provide a second Virtual COM port interface allowing the host PC
to communicate with the target microcontroller through another UART (called bridge UART).
Bridge UART signals, including optional RTS and CTS, are available on the adapter board
only (MB1440). The second Virtual COM port activation is done through a reversible
firmware update, which also disables the mass storage interface (used for drag-and-drop
flash programming).
The modular architecture of STLINK-V3SET enables to extend its main features through
additional modules such as the adapter board.
