HAL_UART_Receive_IT timeout

Posted on May 14, 2018 at 15:24Hello,I plan to take the data from a meter. It works.I would now like to create a timeout on the HAL_UART_Receive_IT in case the wire connected to the meteris cut.Is it possible to create a timeout for this function or...

STM32F7 SPI send/receive issue

Hi!I have an issue with SPI communication on STM32F746 MCU.I have two MCU connected via SPI on my board in 16 bit mode, both MCU`s are STM32F746. At start point it seems normal, but after some time it starts to drop packeges cause CRC32 check(CRC32 c...

STM32F7 register reset value doesn't match the reference manual

Hi all.I'm currently writing my own set of drivers based on the provided stm32f7 header written by ST. I'm a little confused understanding the USB reset values in section 37.15 of the reference manual. The reset values for my GPIO, APB, and a few oth...

Problem in reading 512kB data over FSMC with 8bit Asynchronous Muxed NOR configuration.

Hi there,I have configured ST32F207VGT for FSMC asynchronous muxed NOR configuration, FPGA is connected to the bus at other end. Following is the FSMC configuration done on MCU hnor1.Instance = FSMC_NORSRAM_DEVICE; hnor1.Extended = FSMC_NORSRAM_E...

STM32H7 and SYSCFG_UR2/3 register

RM0433 is very short about the SYSCFG_UR registers. Most URx registers are read-only and probably provides another view at the values of the options byte. The reason to provide another view is not clear to me. However UR2 (BOOT_ADDR0) and UR3 (BOOT_...

Unstable behavior SDADC STM32F373

For a 21-channel temperature measurement tool (NTCs) I use a STM32F373 ( SDADC1 + SDADC2 + SDADC3). I replaced a temperature sensor with a fixed resistor for these tests.The behavior of the ADCs is different and reproducible after startup:Good Case: ...

STM32CubeMX & STM32L4 Library 1.12.0 ADC Problem

Is there a known problem with HAL ADC driver in the 1.12.0 L4 HAL library?I have working code using STM32L4 HAL 1.8.1 that I recently upgraded to latest Cube & HAL (4.26.1 & 1.12.0 respectively) and I have very odd behavior with the ADC after the upd...
