Install PlatformIo

Install platformio extension in vscode, and then install stm32 platform:

MDK-ARM

Windows7x64 virtual machine on Mac

• Download and install mdk-arm
• VC_redist.x64.exe

The pack installer seems useless. Just close it, and the install link is somehow disabled.

Download stm32f103ze DFP and install

MDK4.7

MDK 4.72 + keygen (Menu/License manage/CID), generated key only valid to 2020, but still can use

• ST-link Driver
• STM32F10x Standard Peripheral Library (SPL)
• CMSIS (Core Peripheral Access Layer)

Project structure(https://github.com/drriguz/stm32-examples/tree/master/stm32-led):

Set c++ options:

Set debuger to use ST-link+SW:

Note:

• Don't use startup_stm32f10x_hd.s by Mdk, use the library one
• Don't call SystemInit in main.c, it's already called in startup_stm32f10x_hd.s

LED not blinking

The led is not blinking, but always on, similar as

Issues

• If "st-info" shows no device, then check if the usb wine is good
• Stm32CubeIde does not work with none-original ST-Link device, error:

• If install old version of stm32cubeide, "“STM32CubeIDE is damaged and can’t be opened"
