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...
I am using STM32F103RCTx and STM32CubeIDE for developing a small application.I am tuning a vacuum pump DC motor using PWM signal with TIM1 CHANNEL_1. But I hit a small problem when I start debug the board. The motor is running from the time the IDE s...
Hello,Still trying to get I2S working on the H7...Opened up PulseView to check the clock between another connected device...Much to my surprise, the STM32 is actually outputting 1.027 Mhz average clock pulses instead of the ESP32's 1.024 Mhz. Checked...
Hi everyone!, in my prototype i need some low and high pulse before sending uart datas.. How can i do this? I have already tried using HAL_GPIO_Write and HAL_DELAY and it is not worked.I need an advice for it.Thanks.
Hello,I have developed an application that saves accelerometer data when a machine starts up. This data is stored in the last page of the controller's memory (page 31).I'm encountering a HardFault exception that occurs intermittently, roughly 1 in 20...
I have a custom board with an STM32H730 and a LAN8710A PHY, operated in RMII mode. The board is a new design, based on an older board but with some differences (the older board has an STM32H750). My short-term goal is to prove out the hardware -- a...
