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...
Hello!I have a new project with a STM32F407VET6 and a STM32F103xxx over a RJ45 Jack with I2C.i worked a lot of time with I2C EEPROMs and it works fine, but my communication between the 2 STM's are horrible, or i am too confused.i found the tutorial o...
I'm attempting to implement a USB MSC Device using the USB_OTG_HS on a STM32U5A9J-DK1. I'm using the STM32CubeMX version 6.14.1 and STM32Cube_FW_U5_V1.7.0 to create a USBX stand-alone (without THREADX) MSC device. The project builds and runs, with su...
Hello,To protect the device's software, I am updating the RDP values in my own bootloader software, and to protect it in the event of a sudden power outage, I am also updating the BOR values. I am performing these updates only using HAL APIs. Additio...
Hi everyone,Im currently trying to use SPI with DMA mode on STM32U031G6 with an S2LP,In this specific case I want to obtain the number of bytes present in my FIFO (10 bytes here), but the problem is that my reading through DMA mode does not work.Belo...
Hello,I have custom PCB based on STM32H563ZIT6 with external memory MX25L51245G(W25N01xx in schem.) and Riverdi display. I use ExternalLoader from https://github.com/cturvey/stm32extldr/tree/4dcb141b9cf6da2ee3fddf154d073bb6218a52e5/h5_mx25l51245g. Pr...
