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 ...
Hello,I have designed a board for testing devices. At the heart of the circuit is the STM32F401RET6. With a new circuit board, I can read across the 3.3V rail unpowered (to ground) and see a resistance of about 450 ohms. I was performing some testin...
Hi Experts,I am planning to use stm32l431cb - as it is sufficient controller with 48 pin for my use case. Basically I am trying to find out, how to flash my code into stm32l431cb controller.I referred to a. https://www.st.com/resource/en/datasheet/st...
Good electronical morning to everyone.Context:I find myself needing to enter stm32´s system bootloader during runtime on command.I asigned a GPIO with a simple RC circuit to pull the BOOT0 pin high.The system reset is done by IWDG exception, i just s...
