I need an old version of STM32CubeIDE (1.5.0). I downloaded it a couple of days ago. I wanted to reinstall it, but I removed the installer. Now I want to download it again, and it's not on the list of available versions. Also, the link I downloaded i...

I made my first STM32 board (with STM32H743ZI). The core software is not pure STM, but it's based on an official Arduino core for STM32 (stm32duino), which in general makes things easier, initializing GPIOs etc. I am able to program the MCU (via stli...

In my STM32H7 application I start a timer, stop it in an update interrupt handler (by setting ARR to 0), then when appropriate I set a new ARR value thus restarting the timer. This happens very frequently. During each such period I execute a number o...

I wanted to check speed of trigonometric operations on my Nucleo L432KC. I toggle pin state and look at my oscilloscope. I use Arduino IDE.The calculations for trigonometric functions turned out to take several hundred of clock cycles. I was disappoi...

Thank you very much. I got the software form the support. But anyway, I hope the problem will be fixed quickly and the old versions will be available again on the website. It majorly disorganized my day when I wasn't able to just simply download the ...

I think the core idea of the question, which I myself have now, is what about RS485 being half-duplex? You need a flow control. The DE signal. Since I guess the communication goes both ways. So is it possible to use the ST bootloader in half-duplex m...

Thank you guys VERY MUCH for the encouragement. I planned on learning and using CubeIde before, but it was getting stuck on "downloading software" dialog (I was not alone to experience this bug as far as I checked the internets) and I gave up. But gi...

That was a really great experiment! Thanks for sharing! It's great to know how this behaves under the hood.

Thanks, I'll probably do that. Since I stop the timer inside an update event, then it's already been reset actually. So then it shouldn't introduce jitter when I stop it immediately at the handler beginning. Also, I played with CR1 |= TIM_CR1_OPM to ...
