STM32L4 RTC LSECSSD Error handling. RTC doesnt restart after LSECSSD error detection

Hi After RTC LSECSSD error detection RTC does not start again. ON detection CSS flag I have reset back up domain but and try to restart RTC but it does not start again. Its returning HAL_TIMEOUT on RTC set time. Can anyone suggest me solution or any...

STM32L4 LSE CSS

Posted on May 04, 2017 at 01:58Hello,I'm using STM32L443. I use LSE for RTC and i use LSE for MSI auto calibration. I use a battery on VBAT pin. When i accidentally touched one of the clock pin i saw that there happens an error. The error sets LSECS...

STM32F407VGT on Discovery Board. Timer2 input channel 2 PA1 is not triggering Input Capture interrupt. Timer2 Clock 84Mhz.(HSE with PLL for clock) void HAL_TIM_IC_CaptureCallback() is not invoking even after applying proper signal to Timer2 IC pin.

I have tried to create a PWM signal using Timer1 and then feed that to Timer2 running in Input Capture mode. The Timer1 PWM output is working fine and verified using DSO. But in case of Timer2 the Input Capture interrupt call back void HAL_TIM_IC_Cap...

Can't change SYSCLK in UART HyperTerminal example

When I create the UART_HyperTerminal_IT project in STM32Cube, SYSCLK's source is assigned to PLLCLK:  RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI;  RCC_OscInitStruct.HSIState = RCC_HSI_ON;  RCC_OscInitStruct.HSICalibrationValue = RCC_HS...

Any new CPUs?

When distributors have zero stock, it is hard to know about new CPUs. Are there any? Fast do it all CPUs are interesting and so are Linux CPUs.PS I am 110% happy that I didn't use any of those in my paid designs.

i want generate 3 phase pwm AC signal. i'm using STM32F730. AS per its datasheet its Timer 1 has three channels that can be used to generate 3 phase. But i'm unable to understand how give phase difference {120 deg) between three phases.

STM32 DFSDM simultaneous sampling of 8 MEMS microphones

I am working on a project where I would like to gather PCM data from 8 MEMS microphones, and naturally I found the DFSDM peripheral interesting. The PCM data will be sent over lightpipe ADAT using a SAI but this is out of scope of this post.This is b...

STM32H7 UART BAUD RATE ISSUE

Hello! I'm developing application using STM32H745 with uart interface. The problem is the behaviour of uart baudrate. I configure with hal driver uart on baudrate 115200 and try echo with terminal. The problem is that sometimes i recieve wrong data ...
