brew install stlink
</syntaxhighlight>

<syntaxhighlight lang="bash">

== Install PlatformIo ==

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

[[Image:platformio.png|600px]]

== MDK-ARM ==

Windows7x64 virtual machine on Mac

* Download and install [https://www.keil.com/demo/eval/arm.htm mdk-arm]
* [https://aka.ms/vs/17/release/vc_redist.x64.exe VC_redist.x64.exe]

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

Download [https://www.keil.arm.com/devices/stmicroelectronics-stm32f103ze/processors/ stm32f103ze] DFP and install

=== MDK4.7 ===

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

* [https://www.st.com/en/embedded-software/stsw-stm32054.html STM32F10x Standard Peripheral Library (SPL)]
* [https://www.st.com/en/embedded-software/stm32cubef1.html CMSIS (Core Peripheral Access Layer)]

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

[[Image:mdk-led-structure.png|600px]]

Set c++ options:

[[Image:mdk-led-options.png|600px]]

Set debuger to use ST-link+SW:

[[Image:mdk-led-debugger1.png|600px]]
[[Image:mdk-led-debugger2.png|600px]]
[[Image:mdk-led-debugger3.png|600px]]

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 <ref>https://www.reddit.com/r/embedded/comments/ucohur/new_to_stm_tried_making_an_led_blink_but_it/</ref>

= 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:
[[Image:stm32cubeide-error.png|600px]]
* If install old version of stm32cubeide, "“STM32CubeIDE is damaged and can’t be opened" <ref>https://community.st.com/t5/stm32cubeide-mcus/stm32cubeide-is-damaged-and-can-t-be-opened/td-p/256814</ref>
