Is it possible to ensure that the systick is handled (or the timer that handles the ms tick), and at the same time not interrupt higher priorities unless the irq has been busy/active for example 1 ms?I guess the question applies for arm M0 - M4 in ge...
Hello,How long does the __NOP() function last?Is it the time of a cycle? Or 1/F = cycle time?My MCU is an STM32F401RE, and I understand that the maximum frequency is 84 Mhz.So 1/84 Mhz = 11.90 ns, is that the time of a cycle?In my case, if I loop 14 ...
I'm trying to configure the Bootloader for a STM32G4A1KE processor, but in the AN2606 I cannot find any information regarding this processor (family STM32G41). Although it is listed in the introduction section of AN2606, no further information is gi...
Hello everyone, I am using STM32L433 with external crystal 12MHz. SYSCLK is 72MHz. i am using three usarts (1,2and 3). but after certain time period of execution lapse. STM32L433 goes to hardfault handler and executiion stucks, After debug found that...
When first programming a New STM32L431KC, it does not program or run unless mass erase is performed first.I use IAR and STLINK/V2From IAR, I try:a) Download program - uC does not run, even after resetb) Start debugging session - Does not execute code...
Today I spent some time to fine-tune SAI clock to get standard 22.05kHz sample output rate.However, I do not understand why CubeMX states that "Error between selected" is 0.22%.What is "Error between selected"? Why this error is zero when selected fr...
Hi Can i get the STM32L4R9ZIT6 Component Data .Pcb Design and Layout guide for signal integrity.I need simulation validation standards for the above component.Regards.Raneel.
Is there any inbuilt leap year setting in the onboard rtc of STM32L152RC. If not how to manually configure it. Source code also. Thank You
Hi everyone, I am trying to generate PWM signal and change it's frequency with a potentiometer. I have connected an LED to the PWM output and it blinks only a few times and then stops. Sadly, I don't have an osciloscope to check the signal.I am using...
In my application I have configured IWDG to start running.I would like to prevent the IWDG from resetting the MCU while in stop 1 mode for extended period of time.In the reference manual it says: "Once running, the IWDG cannot be stopped." But in the...
