1, ST officially published two types of emulators: St-link, St-link/v2, other models (St-link Ii,st-link III, ... is either a domestic company production, or a development board comes with;
2, in the St official website St-link State is nrnd (not recommended for new designs), the official has not proposed in the new product design the use this product;
3, ST-LINK/V2 is the official latest main push STM8, STM32 Simulator, internal circuit, interface protection has been improved;
There is also a st-link/v2 version that supports isolation, and order code is ST-LINK/V2-ISOL, which is used to debug STM32 motor applications.
With Jlink can also, but need to take a separate plate (STM32 motor kit, to be removed, but also expensive to die, too troublesome)
St-link V2 This version of the hardware is available in two versions: normal version, with isolated version
However, the common version of the general, usually with the isolated version is mainly used for some of the target board has strong power or strong interference signal occasions;
The st-link/v2 is a in-circuit debugger and programmer for the STM8 and STM32 microcontroller families.
The single Wire interface module (SWIM) and jtag/serial wire Debugging (SWD) interfaces
is used to communicate with any STM8 or STM32 microcontroller located in an application board.
In addition to providing the same functionalities as the ST-LINK/V2,
The St-link/v2-isol features digital isolation between the PC and the target application board.
It also withstands voltages of up to 2500 VRMS.
Various versions of the St-link emulator
