Dear,I have an issue working with STM32L4 USB CDC Device. So I have two separate projects of this. I configure USB CDC Device on the first prooject (COM6), and everything works fine. I then work on another project with a different configure on USB CD...
I’m creating a custom USB HS DFU bootloader for my STM32F429 project, using arm-none-eabi-gcc together with the CLion IDE. I’m having trouble jumping to the application code from the bootloader.The CLion project consists of a bootloader target and a ...
I tried all possible solutions but still not working...need some enlightenment :)I am using STM32F070F6P6 china made breakout board and has no on-board USB circuit so I made it on breadboard. please see attached circuitI am using default STM32CubeID...
Hi,I'm using serial communication with DMA and sometimes the transmission complete interrupt is not triggered (HAL_UART_TxCpltCallback) the issue happens every few minutes, or every several hundred transmissions. I saw https://community.st.com/s/ques...
I'm working on a project where I need to control two WS2812B serial RGB LED strips. These strips are connected to 2 GPIOs which are configured to output modulated PWM to generatate zeros and ones, by letting TIM2 run with DMA configured on CC1 and CC...
I have stm32f429discovery and i used stm32cubeMx to set up usb host with fast32. when I connect flash it works OK. but when I configure freeRTOS it didn't work. when i debug it, I found that the "id" in "USBH_UserProcess" function is "HOST_USER_CONNE...
Hi.I am currently trying to have USB virtual com port to work on STM32L462CEU6. I made simplest project using IDE, just enabling usb then setting the usb class to be CDC. Nothing fancy, no more things than setting the 48mhz clock and flashing cpu. No...
