STM32H743 HRtimer PWM
hi i'm using HRTIM for PWM output.i could complete pwm output. but i want to stop it at pulse count that I want.is there any good way to stop output at i set pulse counts??

Structure confusion DMA_HandleTypeDef vs __DMA_HandleTypeDef
This code is from STM32H7xx_hal_dma.hwhat is __DMA_HandleTypeDef describing ?is it weak ? for what purpose ?typedef struct __DMA_HandleTypeDef { void *Instance; /*!< Register base address ...
DMA Overhead (ADC to RAM)
STM32F446 in my case...When the ADC finishes a conversion and the DMA controller deposits the converter data into memory, what is the overhead ? i.e. How long does it take ? Is this shown in the documentation anywhere ?I would assume that as soon as ...
Precise clock for CAN in stm32l432kc, what's the best approach?
Hi,We are developing a board with the stm32l432kc comunicating thru CAN bus @500kbit/s, and after reading about the internal clock precision (1% at best for HSI16 in the 0-85C temperature range) we are concerned that it could lead to CAN communicatio...
STM32L4S5 enabling internal pulldown
Hi,We are using PF3 for one of our output function and we need to pull that pin down internally. So we are configuring that pin as output enabling clock etc and using LL driver "LL_GPIO_SetPinPull" function with port and pin with argument "LL_GPIO_PU...
Is stm32 micro-controls are capable to calculate Natural Logarithm ?
I am using Thermistor (NTC Type ) as temperature sensor .So to calculate the temperature from adc value of STM32 I am using this formula(taken from this site :- https://www.jameco.com/jameco/workshop/techtip/temperature-measurement-ntc-thermistors....

ST-Link debugging problem / ST-Link Utility problem
Posted on February 26, 2018 at 18:10 Hi, I was doing my thing, writting and debugging code with System Workbench and after a while ST-Link refused to work anymore, out of the blue. I had not changed SWD pins nor related settings. It just stopped ...
RM-Mini-Error (... not sure...): Timer Reset Mode Edge Polarity
Thanks for the nice possibility for "PWM input mode" measurement / frequency measurement - works very perfect on TI1 or TI2.But the register descriptions for SMCR and CCER are somehow contradictory in RM (e. g. 37.4.3 and 37.4.9 ... but concerns also...
