I have question on STM32F777 RTC and super cap

I wanted to use RTC Circuit for Supercap.I have designed circuit (Check Attached snapshot).but i dont get back up time? can anyone explain do we need to do any provision in controller.It seems that capacitor is discharging very fast

Dear Support, Please help to check and confirm if the marking "7B594 9R" is lot number for the part number STM32G474VET6. Please refer to the photo below. Thanks

transfer SPI data from spi4 block defined as SPI MASTER to spi5 block defined as SPI SALVE without success.

ia m using STM32h743II MCU and i am trying to transfer SPI data from spi4 block defined as SPI MASTER to spi5 block defined as SPI SALVE without success.I am using the HAL_SPI_Transmit from the SPI MASTER block (spi4 block) and HAL_SPI_Receive from t...

Odd glitch experienced on STM32F7 TIM8 PWM. - FIXED

I am seeing a very strange glitch from the PWM output of TIM8:CH1 on an STM32F730.The timer is running on 216MHz internal clock, with an ARR reload of 617, giving a ~350kHz PWM output.There is also a no-output Compare on it's channel 2, used to trigg...

For STM32F030C8 is the MCU_ID suitable for a device ID, is it unique? The STM32F0xx products integrate an MCU ID code. This ID identifies the ST MCU part number and the die revision. Since there is no UNIQUE_ID for STM32F030.

I'm using an STM32L412 and would like to start and stop a PWM output through software. Is it possible to use TIM16 and control the break function through software?

STM32F4 / STM32H7 RTC HW BUG - Shadow registers for seconds and subseconds are inconsistent

Hi. I found a bug in RTC shadow registers inconsistency of seconds and subseconds.Subseconds are counted from PREDIV_S down to 0. Then the seconds are incremented and subseconds start again from PREDIV_S.Sometimes subseconds contain PREDIV_S value an...

Hello!!! I'm working with the USB as a virtual com port of the STM32L4R5. If I'm not wrong, the size of the reception data is only 64 bytes and the transmissin buffer is limited to 2048 bytes. It's possible to increase both buffer size? Best regards,

Hii, I am new to stm32 and I am learning to program MCU using Registers. which STM32 should I go for for learning the basics like GPIOs, ADC, UART etc. Thanks in advance for help.
