STLinkV2 In-Circuit Debugger: Pinout, Datasheet, and Programming

Introduction

STLinkV2 is an in-circuit debugger and programmer for STM8 and STM32 microcontrollers. It communicates with any STM8 or STM32 microcontroller on the application board through the Single Wire Interface Module (SWIM) and JTAG/Serial Wire Debug (SWD) interfaces. This article will provide a detailed description of the pin diagram, datasheet and programming methods of STLinkV2.Additionally, you can refer to the STLinkV2 Datasheet from STMicroelectronics for technical specifications and check out the STLinkV2 Setup Guide on Embedded Systems for a beginner-friendly installation guide.

The pin diagram of STLinkV2 is shown below:

1. SWDIO: Serial Wire Debug Data Input/Output
2. SWCLK:Serial Wire Debug Clock
3. GND:Ground
4. 3V:Power
5. NRST: Reset
6. SWIM: Single Wire Interface Module (for STM8 only)

Datasheet

The datasheet of STLinkV2 provides detailed technical specifications and features. Here are some key features:

• Power supply:5V via USB connector
• Interface: USB 2.0 full-speed compatible interface, USB Type-A to Mini-B cable provided
• SWIM features:

Supports application voltages from 1.65V to 5.5V

Supports low-speed and high-speed modes

• Programming speed: 7 kbyte/s in low-speed mode, 12.8 kbyte/s in high-speed mode

Isolated version: STLinkV2-ISOL provides digital isolation between the PC and the target application board, capable of withstanding voltages up to 1000 Vrms

These features make the STLinkV2 a powerful tool for developing and debugging STM8 and STM32 microcontrollers123.

Programming

Programming with the STLinkV2 requires the following steps:

1. Connecting the hardware:

• Connect the STLinkV2 to the PC via a USB cable.
• Connect the pins of the STLinkV2 to the corresponding pins on the target board using Dupont wires.

2. Install the software:

• Download and install STM32CubeIDE (for STM32) or ST Visual Develop (STVD-STM8) and ST Visual Programmer (STVP-STM8) (for STM8).

3. Configure the software:

• Open STM32CubeIDE or STVD-STM8, create a new project or open an existing project.
• Select STLinkV2 as the debugger in the project settings.

4. Programming and debugging:

• Write or import code.
• Download the code to the target microcontroller through the software interface.
• Use the debugging features to debug the code, including setting breakpoints, single-step execution, and variable monitoring.

5. Verify and test:

• Run the program to verify that it functions as expected.
• Perform further debugging and modifications if necessary.
