I found https://community.st.com/t5/stm32-mcus-products/stm32g491kxu6-don-t-have-exposed-die-pad/m-p/625099#M231656 on differences between STM32G491KCU3 and KCU6. Is junction temperature range the only difference between these parts?
Greetings, I'm making a project, using a B-U585I-IOT02A board in which I made a Java program that can flash a firmware (using the USB DFU protocol) and also set Readout Protection to Level 1 through the Option Bytes. The program can flash the firmwar...
Hello everyone,MCU in use: STM32H745XI (dual-core, Bootloader v9.1, CubeIDE 1.16.1, HAL v1.11.3, CubeProgrammer v2.17.0)Hardware status: BOOT0 HIGH works perfectly, I can access the system bootloader over USART1 (PA9/PA10), and program via UART. Hard...
I would need to know how much power does an STM32G0 consume when kept in reset by pulling down the RST pin.Is it specified somewhere?I'm afraid it might be more than what the part uses running a well power optimized software, right?
Hello, I'm using two H533 Nucleo Boards and I'm trying to establish an I3C communication between them. There are no specific examples for this protocol using two of these boards, instead there are only examples for a sensor which I don't have. So, I ...
Hello,I’m currently working with I3C communication using STM32H7S3L8 and encountered a case where the controller (master) sends a read request, but the target either does not respond or sends no data. This section explains: How to distinguish a NACK ...
Hello ST Community,I am working with STM32H750VBTx on STM32CubeIDE. I use UART7 + DMA with HAL_UARTEx_ReceiveToIdle_DMA()to receive responses from a GSM modem.Problem:- GSM responses are stored in my gsm_response_buffer[] incrementally- For example: ...
Hi We are developing a new product based on the STM32U073CCT6 MCU and STM25DV-I2C tag. Question:Is it possible to update the STM32 firmware through the NFC tag? If so, can you provide a sample code?BRGilberto
Hello everyone, I'm reaching out to seek guidance in pushing the SPI CLK line output to, at least, 65 MHz.In theory, this should be possible according to the Reference Manual by setting the GPIO speed to Very High in Vdd = 3.3. Currently, I am able t...
Hello!Can I use 'TRGO2' event signals from Advanced Timers (1,8,20) as event sources for Slave Timers? The Reference Manual (RM0440 Rev 9, p. 381), the Internet, CubeMX and Google - all say "Yes", but in practice I could not use them for Slave Timers...
