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?
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...

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...
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...
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...
İn the datasheet there is no information about that.I don't know if it's compatible or not.I am afraid to burn them :)
