Which peripherals clock need to be enabled?
For the most of the peripheral (e.g. ADC1) it is obvious, but what is withLL_APB2_GRP1_PERIPH_SYSCFG or LL_APB1_GRP1_PERIPH_PWR? Does the voltage regulator work, if PWR peripherals clock is disabled?

STM32L0x2: Combine two comparator outputs
I have a STM32L072KB microcontroller and want to combine two analog signals (they represent a kind of "quadrature encoded signal" with a 50% duty cycle) into one "combined digital output signal", which have the doubled frequency (for my purpose the d...
Resolved! delay function based on timer, overflow safe?
Hello Everybody,I was thinking about a flexible way to implement a µs or ms delay function with a free running timer as tick source. One of the biggest problems that comes to my mind is the overflow problem when the timer wraps around, so that some c...
STM32f103vct6 Uart tx always busy and system is halted.
hello. I have a question using uart(115200, 8, 0,1) in stm32f103vct6.huart3->gstate have been changed hal_busy forever In an unspecified situation and system is halted. I use true studio compiler. and In debug mode at that time, systick interrupt ...
STM32F0 timing of the flags in ISR, especially TCR and RXNE
It seems like we have run into a delicate timing difference of the I2C in STM32F042 and STM32F072. Identical code (coming from the exact same source file) for I2C works fine on STM32F042G4U but has a problem on STM32F072V8T.When doing larger I2C tran...
Is it possible to cascade the repitition counters from timer 1 and timer 8 to a 16 bit counter?
The value of the repetition counter can only be 255 maximum. However, I have to generate over 255 pulses, which I must be able to adjust. Is there still another possibility to generate 65536 pulses without using interrupts?
PWM not working on STM32l431
When I trying to run PWM on PA8 I get no PWM at all. The pin just goes high and I can't understand why. I used HAL example code. The cpu is running at 16 MHz and here is the codeHW_TIM_PWM_Set(4000, 70); HW_TIM_PWM_Enable(); HW_TIM_Delay(1000); HW_TI...

STM32F103 PC13 variable duty cycle waveform
I'm intending to use PC13 as an output to drive the onboard LED, but at some point in my program the PC13 pin begins outputting a 4.4 khz signal with pulse width that varies from 0% to 100% back to 0% and keeps repeating that pattern at approx 4 Hz. ...
