I'm encountering an issue with the update event triggering in STM32 TIM1. I have configured TIM1 to generate PWM signals and set the update event to Center-Aligned Mode 3. However, I've noticed that the update event occurs not only when the timer's c...
I am attempting to set up an encoder on STM32G431RB using Tim 2 which is 32bit but it is only counting up to a 16bit value and going negative. I looked at the register through SFR and only the first 16 bits are active, is there another setting I need...
There is glitch when accessing timer registers using DMA- Halfword memory to halfword peripheral DMA transfer- DMA target is TIM15->DMAR, configured to write ARR register.- TIM15 dithering enabledUnder these conditions, bits from ARR[3:0] will end up...
Hi all,i'm working with a STM32F469i-discovery board trying to read the external signal at 32kHz coming from an RTC module. The oscillating signal voltage is a CMOS type. I'm using TIM2_ETR input located on pin PA15 configured as follow. I'm not abl...
Hello,I am attempting to set up a timer PWM output to have a set 600s period with a variable duty cycle based on a potentiometer input using an STM32G030J6 MCU. I've setup PWM output timers before will little difficulty but this time I'm having a di...
Hello,I'm working on a STM32F103V8. The TIM3 should decode the signal of a rotary decoder.When I turn the rotary decoder clockwise the counter of TIM3 goes up.When I turn the rotary decoder anticlockwise the counter of TIM3 goes up.The MX_TIM3_Init i...
Hello. I built a project with STM32F407 DISCO board, I record audio and store it in USB OTG for later playbacks... Anyways, I've been using the onboard MEMS mic as well as the 3.5 audio jack. But I want to replace those for an electret mic and a tiny...
Hello,we are having an issue on the STM32H730 ; we would like to have a Timer Capture triggered by the USB OTG SOF signal. This should be straightforward since the USB1_OTG_HS_SOF signal is connected to TIM2 ITR5. However, we never managed to have th...
Hello,I am attempting to generate a waveform with a period of 33ms. In-between each period, I need to toggle the timer output 5 times with a varying timescale. My initial thought is to do this using a timer in output compare mode and then update the ...
