according to the documentation for the iic bus, devices must create start conditions, even if the devices ignore the ACK bit, but stm32f103, in fact, ignores the start bit without the ACK bit. if this is not the case, then where is it written in the ...
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....
Should I give up on the STM32H series and move to the STM32MP series?
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...
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.
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...
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...
