Cannot get One-Pulse mode working

JustSomeGuy · ‎2024-06-13

I know this might be a pretty basic thing to have issues with, but after banging my head against the wall on this for days, your snark-free assistance would be greatly appreciated.

I am using a B-L072Z-LRWAN1 and trying to get timer 2 channel 1 to provide a pulse output. I cannot seem to even get the timer counting. Here is my code, please tell me what important thing I'm missing here.

Cube's idea, what's "One Pulse Mode" is different from yours.
Can you please explain what you mean by this?

This. (the first two sentences of that post)

What exactly do you mean by 'read Cube?'

I mean, read its source code, analyzing it with the understanding of TIM working you already have from reading the Reference Manual.

The comments to given functions may or may not be helpful (they also form content of the Cube's manual, so you may to read them at either place).

different use cases and end result than what I need

You shouldn't expect to find a ready-made solution to your use case. Rather, you should build an understanding of what the hardware is capable of - from its description in the Reference Manual - and then build from there. Cube may help or hinder this effort.

Everybody has different use case. That's why the utility of Cube - which inevitably caters only to a limited number of use cases, those deemed by Cube's authors to be typical - is limited, too.

In this particular case, a number of threads hints at the fact that Cube's notion of One Pulse mode is different from most users expectation. I personally don't care, I don't use Cube, I am just trying to point out these facts to the users. Most Cube users expect some Cube-based solution, anyway, and as I don't use it, I can't provide that.

You can also wait here until some Cube-versed user chimes in with a solution for your particular case.

Cube's idea, what's "One Pulse Mode" is different from yours.

Don't use Cube if you want control, write your own code. Or, read Cube - it's open source - and understand, what does it do.

You should search this forum, too.

I did, but every forum post I find has different use cases and end result than what I need. If you can link me to a post which is very similar, that would be appreciated. Vague answers like these just create more questions. You would do very well in politics ;)

Thanks for the answers! This is good to know about Cube. Once I get more familiar with this family of MCUs I plan to ditch the cubemx and HAL drivers.
