For better learning STM32 programming and debugging

Hi there,

I have been using STM32 nearly 10 years.

I did modification according to company requirements. But it doesn't mean I am very good at C,C++ or else. I understand coding if it'd in C or C++ format.

I understand mathematics, logics and conditioning.

Kindly suggest materials/ guidelines/ books/ tutorials that might help me to write coding/ debugging and finding root cause of failure.

Let's say staring with ARM cortex type M0.

98% of this is not specific to the particular microcontroller - these are general, transferrable skills.

Most of it is down to being able to analyse a problem and define a solution.

But here are some links to ST's own learning & reference materials

You can't be so narrow. You need the general topics like the Cortex-M0 architecture, general electronics, and general C programming.

For understanding the Cortex-M architectures, Joseph Yiu's Definitive Guide books are required reading:

https://www.amazon.co.uk/Books-Joseph-Yiu/s?rh=n%3A266239%2Cp_27%3AJoseph+Yiu

For understanding the STM32, the device Datasheet and Reference Manual are key documents - you will find these and much more on the Product Page for the chip in question.

Hello @Md Mubdiul Hasan

For the cortex-M0, i may suggest you the documents available on this link. Also, you can check our progarmming manuals for devices using cortex-M0 et Cotex-M0+ . Also, i may suggest you to contact ARM throw there community or to try there online trainings.

Best Regards.

#GettingStarted

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

Andrew,

Your suggestions looks suitable.

I have few different STM32 board to play with.

Let's try your materials.

LCE

Principal II

Reading helps, but I recommend doing that in parallel with working / playing with some real programming environment and hardware.

So get a Nucleo board, install STM32CubeIDE - and just do it!

:thumbs_up:Indeed! :ok_hand:

Don't waste time with a blue/black/whatever pill - get a genuine ST Nucleo, which includes a genuine ST-Link, has a load of ready-to-use examples, and is well-known and well-supported by both ST and this community.

Getting Started steps:

Write some code to blink an LED connected to a pin, using a simple software loop.
Learn how to use your debugger to step through your simple LED code, look at your variables, set breakpoints, etc
Learn to use the UART to transmit a fixed "Hello, World " string.
Again, practice using the debugger with it.
Adapt your code to be able to send a variable string.
This will be invaluable for future work!
Keep practicing with that debugger...
Adapt your code to be able to receive on the UART
By now, you should be well prepared not only to write your own code, but also to debug it.

PS:

Applying the above to a specific project:

This does kind of trouble me, that in this time you've not got a clearer path forward, and got some rather fixed and narrow thought processes.

Perhaps a "Learning how to learn" course might be something to consider?

Now we all approach these things differently, I tend to approach via inference and triangulation, as Andrew indicates a lot of the technical details between MCUs is highly transferable, most being more the same than different. Triangulation would be to get information from multiple perspectives, say multiple texts about materially the same thing, but with different approaches and view-points that different authors and use-cases bring.

The internet opens the door to be able to find a lot of material, but you need to filter and focus that.

Do thing incrementally, there's not going to be a mind-melding approach where you're going to get to understand all the details all a once.
