Hello,I'am currently programming on a STM32G473. I'am sending CAN Message via the FDCAN peripheral.In generally everything works, all my messages I put into the Tx Buffer are sent.But in one little detail I'am confused:In Figure 669 its described, th...
Hi,I'm encountering an issue with my STM32H750 MCU. I download my program to the flash via the UART interface using STM32CubeProgrammer. The MCU can work well for a few days, but suddenly crashed. This problem occurred randomly on 2 out of 15 boards ...
In some readings, I saw that there are some STM32s that can be used to control Switched Mode Power Supplies. Are there any suggestions for articles with more details on the subject?I am writing a book about "SMPS" and would like to dedicate a section...
Hello,I've designed my own PCB using the STM32H533CET6 microcontroller. However, when I try to connect to it using an ST-Link V2 via SWD, STM32Cube Programmer gives me the error: "Cannot identify the device".I've already tried connecting under reset ...
I'm using a STM32L151RBT6 and trying to debug with a STLink V3.The debugger loses connection when I encounter the line:PWR_VoltageScalingConfig(PWR_VoltageScaling_Range3); Specifically, when it changes the PWR-CR Bits 12:11 (VOS). I have no issue cha...
Hello, I've just received my custom PCB with an STM32H743VIT6 MCU. It has a Samsung eMMC connected to the SDMMC1 interface (MMC 8 Bits Wide Bus) : (I'll link the eMMC datasheet below.) I'm encountering some issues while initializing the device with ...
Hi ST team, Today I have an issue in my hardware.I flash a software via STLink in debug mode succesfully. When I start the program, the console shows that "cannot read register..." or something like that :( I cannot remember.After that, STLink cannot...
I have a 12V GPIO high logic input on my board. Should I convert it to a 5V logic level or a 3.3V logic level? Previously, I have implemented 12V to 5V logic level conversion and already have components for this conversion in my inventory. If feasibl...
Dear STM team,do you consider to add "Programmable IO" (PIO, as in RP2350) or FlexIO (as in NXP MCUs) to your chips?It would be really cool: often I need interfaces on MCU which are not available as a peripheral devices, such as: MDIO (Master), JTAG ...
Hello,I've a short question - is RSS preflashed on eval boards or it is only flashed when specific part number is ordered?
