I am having a problem with a timer. I use CubeMX LL drivers, with basic time-base timer configuration.STM32L100RCT6, TIM6 and TIM7. Core Clock = 32MHz, PCLK1 (TIM6 and TIM7) = 32MHzPrescaller = 31, which should set timer to tick at 1us. ARR value is ...

CubeMX systick initialization on STM32L100RC (DISCOVERY board) is invalid when used with RCC LL library.Steps to reproduce:open CubeMX and select STM32L100 DISCOVERY boardinit peripherals with default stateproject settings:advanced mode.c/.h pair out...

I've reported a STM32CubeMX bug, but I am afraid that there is no one to look at it. Is there any better place to report bugs/issues? Things I've reported are quite a blocker for me and I really need to know if there is anyone working on it, or I'll ...

If Makefile is set as output Toolchain/IDE on STM32L1 (specifically STM32L100C-Discovery board, STM32L100RCT6 onboard), CubeMX generates invalid (unparsable) Makefile. In my case, this were project settings:Generated Makefile has a missing '\' (and d...

My question is rather what is the advantage of writing LL_TIM_EnableCounter() instead of TIMx->CR1 |= TIM_CR1_CEN ? Why does someone choose a "library" of poorly documented one-liner functions instead of an extensively documented register interface, ...

You don't even have to start and stop the timer every time, just leave it running, and reset the counter whenever the start of an interval has to be marked.Both of you are right: this is not the right approach and what I reported here is actually onl...

"General rule, fix/workaround issues attributable to third-parties, they are not responsible for meeting your deadlines."I don't agree. I don't expect my issue to be fixed on a demand, and I understand that there are many issues, customers, prioriti...

Duplicated line, but with a valid syntax:C_INCLUDES = \ ... -IDrivers/CMSIS/Include \ -IDrivers/CMSIS/Includeis also generated for STM32F051 device. Makefile is not ovewritten on regeneration as with previous version.

In fact, there is a whole lot of other bugs I've stumbled upon: changing RCC driver mode: HAL <-> LL does not include all files/delete references on project regeneration. HAL systick does not work (interrupts or something? - uwTick is not incremented...
