I'm running IDE version 1.13.1 on MacOS 11.7.1 on a MBP with a dual core 2.8Ghz i7. Unlike every other IDE / CAD package that I use, STM32CubeIDE pegs my CPU really high and spins up the fans even when doing NOTHING. As in, there is no project open, ...

I noticed the LIV3F has a built-in DC/DC switch according to its block diagram. Does anyone know where in the spectrum the switching noise lies? I need a really low noise floor in the marine VHF band (155-162MHz) and the module will only be millimete...

I have a minimal prototype circuit (breadboard actually) with this schematic: The firmware initializes a few peripherals (including the RTC) and enters an infinite loop calling __WFI(). Nothing else happens and nothing else outside the BOOT0 pulldown...

How do I obtain one? Cube isn't helpful -- this isn't a filter parameter. I need an MCU with built-in backup battery domain for the RTC. I don't want to build anything external and the design must not be capable of powering up the core from the batte...

I can't find any forum for the Teseo so I'm asking here. I need to know if it's appropriate for a very sensitive receiver in the sub-200MHz range. If the module contains any DC/DC switches that raise the noise floor in these frequencies then it's a n...

I ended up ditching the ST IDE and going with Makefile based regular Eclipse. If I have time, I will explore VSCode as well, as I really liked it a lot when I worked on ESP32 stuff.

The STM32 in this module appears to simply provide an AT interface for the Altair 1250 baseband SoC. You will never program it. You will simply interact with it over a UART. Every Altair based module has some kind of MCU to provide that function, Mur...

A few things I do with every ARM Cortex:Compile with the link time optimizer (-flto)For release builds, unless I absolutely need speed optimizations, I optimize for size (-Os)Let the linker remove unused sections (--gc-sections)Link with newlib-nano ...

Thanks, @Community member that's a nice way to say "RTFM" :>

It turns out that the culprit is VBAT monitoring via the internal SAR ADC. 31uA is a lot of current, and there is no way to buffer the voltage source since it's wired internally. So the only viable approach is to enable it once in a blue moon, sample...

Re: The LBAD0ZZ1SE module includes a STM32L462REY6TR microcontroller, I'm not interested in using STM32L462 CPU peripherals I only want him to be as a modem who receives commands from outside to make communications is it possible?
