Hi everybody,I have TIM15, configured to PWM generation, in one shot configuration, using OC1N output. The output is set to 0 and timer disabled.. When I later initialize TIM1, the output of TIM15 goes high at the instant the Update event is generate...

I have a project which uses both OPAMPs. For both OA I use dedicated VINM pin.OPAMP1 works correctly.OPAMP2 behaves like the dedicated pin (M2 ball) is not connected to the input multiplexer.I 've tried - mode FOLLOWER: OK - mode STANDALONE, reconnec...

I am unable to switch on the AUTOFF bit in ADC4.DS reads about ADC_PWRR/AUTOFF: The software is allowed to write this bit only when ADEN bit is cleared to 0 (this ensures that no conversion is ongoing).But if this bit is set, the ADC doesn't set ADRD...

Is it possible to switch VREFBUF clock off after configuration for power save? So the clock is off and the buffer is providing Vref.In DS there is no mention about it (e.g OPAMP has this note).

I have LCD connected to FSMC, 16bit parallel interface.It works, but all signals are twice slower.SYSCLK is 120MHz (checked using MCO), HCLK divider is 1 (checked with debugger).Timers TIM2, TIM3 and TIM4 give expected results, so the system clocks ...

Bingo!That explains how are the two timers connected, although I didn't create any logical connection between them. The fundamental point is that the output reacts to trigger event in OC Fast mode, although the slave mode is disabled. IMHO this shoul...

Sorry for delay, factory holiday :)Attached two files, just before and just after LL_TIM_GenerateEvent_UPDATE(TIM1) .TIM1, TIM15 and GPIOB register content.Differences: - TIM1 SR UIF set (lines 63, 64) - GPIOB IDR ID13 set (lines 332, 346)(I have...

>Always copy/paste coherent portions of code. Best, prepare a minimal but complete compilable example exhibiting the problem.I did that, but after isolating the problematic code I merged two functions into one, as I have answered to @KnarfB. So I hav...

I am sorry, I merged two init functions from two modules into one example code. Since the init structure is fully initilized, it is sufficient to delete the second definition and there is no common data between the two initializations.Tomas

Hi @Amel NASRI ,Thanks for investigation, the problem persists. See the attached snippets of code, principal schematic, a cut from real board routing and X-rayed board, confirming there is not bad connection under the M2 ball.Summary: - when compiled...
