I am working on NUCLEO-U575ZI-Q. The code is generated with STM32CubeMX (using STM32CubeIDE) and the application uses ThreadX, which was added to the project using CubeMX.When a thread call any function that would lead to a suspension of the thread, ...
Hello. I am getting fault error or uart_waitonflaguntiltimeout error when receiving data from UART via DMA on STM32F4 series microcontrollers when the power of the device on the other side is turned off. What could be the reason for this? What should...
Hi!I'm using a custom PCB with STM32F767 on it with LAN8742a for Ethernet communication.Just to mention, I'm totally new to Ethernet topics.I have already search for an very simple example on how to just test the connection from the STM to LAN8742a (...
To whom it may concern:We are currently developing a wearable devices, which is running on a STM32L031. In Bootloader mode, while I am trying to write data to vaild RAM address(0x20001F00), it returns NACK. Every step is followed instruction, but it ...
Hello Everyone,I have STM32MP157F-DK2 board has an ARM Cortex-M4 chip that supports a frequency range of approx 209MHz. It takes about minimum 3.02 microseconds (Attached Screenshot) to achieve 40 clock pulses on this board. I also tried the STM32 Nu...
Hello everyone,I am doing project that is based on a B-L072Z-LRWAN1 core that has a couple of sensors connected to it. One of them is an ADC sensor that measures the humidity of the ground.My problem is that I would like to send the data from an exte...
Hi All, We ran the example application code on our board with STM32U575VIT6Q and the USB CDC is not enumerating,whereas USB DFU mode is working when we trigger the boot0 button while powering on or resetting the devicehttps://github.com/STMicroelectr...
When I try to add USB_OTG_FS (host only) to a project which uses FreeRTOS the code locks up on initialisation of USB_OTG_FS. When USB OTG FS is added, a call to "MX_USB_OTG_FS_HCD_Init" is added to "main" function. It goes before a call to "osKernelS...
Hi,Currently, I am working on a project where we need to transfer data from PC to uC (STM32L4 series) at a high rate (real-time application). So, we have decided to use USB 2.0. First, we tried the communication device class, but it wasn't fast enoug...
I use STM32H745xi discovery board. When i do some test, i download code that Cortex-m7 will enter standby mode after power on 3 seconds. And i set wrong wakeup pin(wakeup pin 1¬ config PA0, it should be wakeu4). After power off and power on, i fin...
