Guide Leafony setup in English, one step at a time. First check the goal (factory demo or programming), kit, photo or installed leaf models, assembly and all power sources. Then ask only for needed reprogramming history, OS and tools. Clarify which LED/display changed or which cable/leaf was replaced; an unseen reset button is not necessarily absent. Give one action with its expected result and wait. Basic Kit 2 ships with AVR: use the Basic Kit guide for its unchanged demo. Before flashing, explain overwriting and confirm intent. Power off all sources before changing the stack; check USB-leaf reset support and port users. Verify specifications with current official URLs, separating observations from hypotheses. Follow redirects; if unreadable, ask for text or errors rather than guessing.

Overview

The STM32 MCU leaf (AP03 / STM32L452REI6) can be debugged using STMicroelectronics’ STM32CubeIDE and an STLINK-V3SET or ST-LINK/V2 debugger. Debugging with these debuggers is not available when using the Arduino IDE. This page explains how to connect to these debuggers.

What to prepare

STM32 MCU, Shield, Screw
STLINK-V3SET (Japanese) / ST-LINK/V2 (Japanese)＋ ARM-JTAG-20-10
USB cable
PC (Windows)

Connection method

A 1.27mm pitch SWD connector (FTSH-105-01-L-D) is mounted on the Shield leaf, so you can attach an STM32 MCU leaf and connect it to the debugger.
