UART Overrun error

Hello,I transfer data by uart interrupt(Uart_RX_IT_Start()).Now UART overrun error is occurred continuously.Should I have checked any point?I want to use the uart interrupt, not DMA.Thanks.

How to take a reference clock out from stm32h7 microcontroller?

Anyone has a dhrystone DMIPS/Mhz score on a STM32H7 M4 core ? I only got a 0.37

I used the sram and got a 0.37 , Pretty sure this is not right. I use -O2 and hard-float, others remain default.Can any one tell me what should I do next?

What is the state of the GPIO of the STM32F767ZIT6 during reset and after reset before configuration?

The notes in the STM32F76xxx data sheet DS11532 Rev 7 give 2 different answers to this question. See attached. I'm guessing the default state of the unconfigured GPIO is "Floating Input."

Toolchains build around vim editor

I personally like Vim as an editor. But it lacks of toolchains support for embedded development especially on Windows operating system. May I know if someone manage to find the right recipe?How do you get compiler ?How do you get the debugger?How do ...

I cannot get Chinese AD9954 DDS Signal Generator module working with STM32F1xx. Can anyone help?

Some details:issue: there is no signal generated at all by the DDS boardmodule is this: ttps://www.aliexpress.com/item/1005002747924243.html?spm=a2g0s.9042311.0.0.6e454c4d304D3uI tried this code: https://github.com/JQIamo/AD9954-arduinoI dont have ex...

What is the efficient way to measure the time taken by ADC DMA conversion?

I toggle a GPIO pin in the ADC call back function, I get time values on the oscilloscope close what is the supposed to be according to the datasheet, is that correct and efficient? Is there a method better maybe?

STM32F411 Blackpill : fonction HAL_UART_Receive(UART_HandleTypeDef huart, uint8_t pData, uint16_t Size, uint32_t Timeout)

Bonjour,j'ai un système communicant avec des cartes identiques possédant des modules STM32F411 CE8 black pill . une carte est maitre et les autres cartes sont toutes esclaves. je suis en mode "UART_TwoBoards_ComPolling"mon IDE est STM32IDE avec les ...

Resolved! What is the flash configuration of the 1MByte STM32U5xx MCU's?

The reference manual of the STM32U575xx gives the flash configuration in `Table 44. Flash module 2-Mbyte dual bank organization` but this only takes into account the 2MByte flash size.We use the STM32U575CG which only has 1MByte.Is it still dual bank...

Resolved! Hi, Please. STM32F405RG - REV 2 The same code of HAL_FLASH_Program works well in main function and not in interrupt subroutine ? Best regards. Henri
