HRTIM burst mode missing pulses in one period
My application is using HRTIM in burst mode: PWM is generated part of the time by specifying a period and an idle/run duration based on common tick (TIMA counter).Period (HRTIM_BMPER) is set once at init and idle duration (BMCMPR) updated every 20us....
I cannot locate the STM32H757 chips for sale anywhere, at least not at anything below extortion level prices. On the other hand the STM32MP1xx series are available everywhere and are still at reasonable prices. Is this a push to shift technologies?
Should I give up on the STM32H series and move to the STM32MP series?
Resolved! relocation of main source and IRQ vector stm32f103
hello! I'm working on stm32f103 and I found one problem which has a weird solution. In my project, I have a bootloader and main source. I use the 0x800000 address to start the bootloader and 0x8008200 to begin my main project (the bootloader jumps to...
Resolved! RTC ICSR_INITF (init flag) doesn't set! NUCLEO-U575ZI-Q
Hello friends! The thing is I have been trying to start the RTC, enable backup domain in PWR, Connect RTC to the bus, set the INIT bit - so far so good, the Ivoid RTC_init(void){ RCC->APB3ENR |= (RCC_APB3ENR_RTCAPBEN); //Power the RTC up PWR->DBPR...

I am getting hard fault in access the HAL_Delay API.PFA for call stackcan anyone help me on this problemthanks.hard fault-->forced hard fault -- undefined instruction error.
Resolved! Problem changing PWM Frequency on the Fly
Greetings,I am using STM32L151RET6 controller. I have selected timer 5 for square wave generation. Frequency to timer 5 is 1MHz. I am starting to generate 10Hz square wave and increment the value by every 10Hz. After reaching 430 Hz pwm output is cor...
Resolved! Timer base event without interrupt
Hello everyone,I got a time1 on STM32F103C8 running at 72Mhz with settings:If I used an interrupt, I would get callback every 30 seconds, however I want to do basically same using polling method, is there a register or a HAL function I can use to che...
Configure SPI or I2C for continuous clock
In our STM32L5 based design we are using HSI16 to drive some clocks (SPI1). one way to route HSI16 clock is through MCO. is there any other way we can route this clock. 1. Can we configure I2C or SPI1 to route its clock on some GPIOs ?2.Continuous wr...
