Hey all! Does anyone know the cheapest option for a STM32 chip that can simultaneously do USB as a Host and as a Device? I tried using the product selector but the issue is that it didn't list price as a filter option, so I thought I would ask here.I...
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...
Hello,I am using the USB CDC of NUCLEO-F767ZI board. MY firmware can transmit and receive OK through the USB CDC. However, I cannot receive more than 64 bytes, only the first 64 bytes are received. The transmission is OK, it can send more than 64 byt...
