Get early access to the next-generation STM32Cube HAL drivers for STM32U5A major update to STM32Cube HAL drivers, called HAL2, is now available for preview on GitHub. It supports the STM32U5 series. Building on over 10 years of experience, HAL2 deliv...
We are developing a single pair ethernet board using STM32H725VG as MCU and DP83TD510E (Texas Instruments) as PHY. MCU and PHY are interfaced through RMII mode (10Mbps).When we run our application, the problem is that MCU drops some ethernet packets ...
I have a GPS module and I use it by connecting it to my computer via USB.I also want a CAN bus output. Can I use the STM32F730R8T6 processor?How can I introduce the information from the USB to the STM32 processor? Which pins should I use?After doing ...
Hi,I'm trying to run the Getting Started firmware for the B-L475E-IOT01A board but I'm having problems to connect to WiFi. The error messages are:"ERROR: C:\STM32CubeExpansion_Cloud_AWS_V1.4.1\Middlewares\ST\STM32_Connect_Library\core\net_core.c:327 ...
I have a strange issue. I used the SDIO Interface on a F2 and a F429 without issues. But on the first usage with the F446 i run into a strange problem.With the Logic Analyzer i am observing the communication.Card Init:Requesting Card Type, CSD and CI...
I'm not able to conclude the FreeRTOS demo application for the B-L475E-IOT01A2 board. I'm following the instructions given in FreeRTOS User Guide.After compile and upload the firmware to the B-L475E-IOT01A2 board, two sort of problems are happening:1...
Hello,I'm testing with a NUCLEO-U575ZI-Q, I'm testing with the examples STM3Cube_FW_U5_V1.1.0.0jects_NUCLEO-U575ZI-Q. The minimum consumption I have achieved by modifying the code somewhat is 118uA seems very high to me.With other models of NUCLEO I ...
Hello everyone,I have a device based on a STM32H753ii which has an USB-OTG interface that is used for both serial communication and for mass storage mode. This last one is to have access to an EEPROM that is also on the same PCB.Normally, if we build...
What is the effect of USBH_MAX_DATA_BUFFER ? If I increase the value of this would it make my USB read faster ?
