I just go the NUCLEO-L552ZE-Q dev board. STM32Cube IDE Version: 1.5.1Build: 9029_20201210_1234 (UTC)Using 1.3.1 FirmwareThe base CDC code generated by the IDE does not seem to work. It does not enumerate and if I try to send something I get a hard fa...
Hello,When using an MCU with USB FS capabilities, do I need an external IC to be able if an SDP, a DCP or a CDP was plugged in ? Or can the MCU do the job ? Apparently yes, but I struggle to find evidence of this, especially in the datasheets or in t...
Hello! I have a problem. I created a USB audio device project in CubeMX. Then I changed the descriptors and related functions to get a device like a microphone. The device is detected correctly in the Windows system. But there is a problem: DataIn en...
Hello community,I'm experiencing difficulty when debugging my software.I'm running Mac OS Catalina with a L433 Nucleo, plugged into my USB-C to USB-A converter.I wrote a very basic "echo" program to take my USART input and echo it back to my Mac.I ke...
I am using STM32F072RB.I have enable the FreeRTOS CMSIS1.I have created two tasks which uses the same UART for transmitting data.I want to use the semaphore concept to use this shared resource between two task.The task as belows:TASK 1 High priorit...
Hello,I need your help to recognize my issue correctly, please help me,background:I am having trouble using the stm32l053RB NUCLEO development board for USB protocol parsing.issue：When using timer to generate PWM, once the USB receive data is confi...
Hi,Is there a date to STM32CubeMX/STM32CubeH7 release with Azure RTOS?
I am trying to make USB work on a custom board. On our board the VBUS and ID lines from the USB-B connector is left floating, Because we always want to be in device modeSo to compensate for this I am using B-peripheral session valid override. This in...
Hi,I design a custom USB - UART using STM32F042F6This is my schematic This is pin configuration in Cube MXThis is the board layout When connect by USB cable, win10 pc recognized it as DFU device without problem.I tried STLINK Utility to just connect ...
Hello community,I am facing massive problems using the SPI1 with DMA transfer on the STM32H743 Nucleo board. Using interrupt based transfer works, but when I try to use DMA I always receive zeros in the receive buffer and I get an overrun error from ...
