Correct way handling UART transmission without overrun STM32L496
Hello. I have packet each 200ms (8 byte) and i have sometimes from computer register set function, again 8 bytes.And time to time getting USART ovverrun error. That is not a big deal, but i just don't want to miss correct register write to MCU event....
Resolved! STM32H7 returns extra byte in Get (device side). What is the extra byte?
When querying STM32H7 system bootloader with GET (0x00) command, it responds with:31-00-01-02-11-21-31-44-63-73-82-92-FF-79in e.g. STM32F4 series the response was:31-00-01-02-11-21-31-44-63-73-82-92-79The AN3155 document does not mention the extra by...
In the latest 1.8 version of the f1 of cubemx 5.3, the U disk program is configured to read, and the U disk is not responding, not enumerated. What did the 1.8 version change?

Resolved! STM32F429 video output protocol for a SVGA display
Hello,I'm looking to use the STM32F429 to output data to an SVGA display. The supported video formats for the display are shown in the image below. The display is actually a monochrome variant, so color is not relevant as the RGB lines are tied tog...
PRIMASK bit always reading 0, unexpected behaviour when changed using debugger.
I am writing an app to evaluate the STM32L433. I am using the RTC peripheral, setting an Alarm, and processing an interrupt on it.During my development, I wanted to disable interrupts momentarily using the debugger. For this, I tried to modify PRIMAS...
QSPI error at border 0x01000000
Chip stm32f746, memory S25FL256S in 32-bit address mode.An error occurred while sharing DMA and reading directly on the edge of the address 0x01000000.The error occurs when the high fourth byte of the memory address is changed. When DMA and reading o...
SDRAM and adc warnings
I am evaluating the STM32F767NIH. I am finding the warnings a bit unclear for the FMC. A brand new project with only the fmc shows a warning triangle that I can't seem to get rid of. I have checked Clock and chip enable SDCKE0+SDNE0, 2 banks, 13 bi...
Wrong readings from FRAM via SPI after switching the Bitrate on STM32H743
Hi All,In my system (STM32H743) SPI6 is used to address 2 slaves with different bitrates. So I have to reconfigure the bitrate every time I want to address the other unit.One of the slaves is an FRAM so reading from / writing to the FRAM is preceeded...
Resolved! STM32H7 - USB HS Host - nothing happens
Hi there,I got some troubles getting the USB Host system working on the STM32H746ZI.Worth mentioning is that this is no dev board here, just a plain H7 mcu on a DIY bread board. It is properly supplied with filtered 3.3 and 1.8V. Got UART, I2C, LCD...
