How to begin with Murata Module and STM32 in general

[NMeno]

Hi, I'm new in this world of ST. I have relative experience with Arduinos and LoRa, but now I want to do things with more resources. In particular, I am interested in the LoRa module from Murata and I bought the Discovery Kit B-L072Z-LRWAN1.

What I ask is a bit of guidance in this regard.

What IDE do you recommend? (I'm used to the Arduino IDE)

Where can I read things about it?

To program the B-L072Z-LRWAN1, I always prescribe the STLink or can I do it with a USB-Serial adapter?

A library to read a sensor (i2c for example) with the ide of Arduino can be used for this type of MCUs?

Any recommendation is welcome.

Thank you very much!

Suggest you use Keil, there are free licenses for ST Cortex-M0 parts, and significant clowning around compared to GNU/GCC - Eclipse platforms. Mileage varies, pick something you like.

The I-CUBE-LRWAN software has projects compilable with Keil

Review, build and test the projects provided, review context of code with respect to Semtech stack

The ST-LINK is the best way to program debug.

You can use the BOOT0 pin to get into the System Loader, and it's USART/USB programming modes.

Review AN2606 and related doc for the functions/protocols.

You'll have to code routines in HAL to talk to I2C peripherals.

Not familiar with ARM CPU, review Technical Reference Manuals, and supporting books like Joseph Yiu's Essential Cortex-Mx series. ST also has Data Sheets, Reference Manuals and Programming Manuals, review/skim those to understand the lay of the land and where to find detail if you need it.
