1、ST官方正式出版了两种仿真器:ST-LINK、ST-LINK/V2,其他型号(ST-LINK II,ST-LINK III,…)要么是国内公司生产,要么是开发板自带的;
2、在ST官网ST-LINK的状态为NRND(not recommended for new designs),官方已经不建议在新产品设计中使用该产品;
3、ST-LINK/V2是官方最新主推的STM8、STM32仿真器,内部电路、接口保护均作了改进;
还有一个支持隔离的ST-LINK/V2版本,order code是ST-Link/V2-ISOL,多用来调试STM32的马达应用。
用JLink也可以,但需要外带一个隔离板(STM32电机套件上有,要额外拆下来,而且也贵的要死,嫌麻烦)
ST-LINK V2这个版本的硬件是有两个版本的:普通版本、带隔离版本
不过常见的还是普通版本的,一般带隔离的版本主要用于一些目标板有强电或者强干扰信号的场合;
The ST-LINK/V2 is an 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
are used to communicate with any STM8 or STM32 microcontroller located on 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.
