Assistance with Setting Up STM32L031F6P6 and Connecting it to ST-LINK

[MedSid]

Hello,
I am currently working on a project involving the STM32L031F6P6 microcontroller, and I would like to ask a few technical questions:

• What are the basic settings required to initialize and get this microcontroller up and running?

• How can I properly connect it to an ST-LINK for programming? Are there specific pins that must be used?

• Are there any general technical tips that could help me get started with this STM32 model?

• Are there any important notes regarding power supply or protection of the surrounding circuitry?

Any guidance, technical documents, or advice from experienced users would be greatly appreciated.
Thank you very much in advance.

Here is the hardware design guide for the L0xx family:

Getting started with STM32L0xx hardware development

To program, you need a programmer such as STLINK-V3MINIE. Put the 14-pin header on your board using the pinout given in the user manual. Alternatively, you must connect GND, SWDIO and SWCLK at a minimum. The programmer does not provide power.

Look at the nucleo board for inspiration. Download the schematic from the board's CAD Resources page.
