Running an stm32f407...I have some flash programming bootstrap code that runs in RAM and on completion the device is reset by writing 0x05FA0004 to the syscfg->aircr register. When run from flash this works fine but running it from RAM it ends up at ...
STM32l475 USB host USBH_UserProcess() not progressing to HOST_USER_CLASS_ACTIVE
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...
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...
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...
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...
Posted on April 05, 2018 at 10:56We are trying to increase the clock speed of our STM32 on our custom board but we encountered some difficulties.At the moment, we set a clock of 56 MHz, using HSI and an PLL of 112 (with CubeMx). It works fine.But wh...
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_...
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: ...
