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...
Hi all,I am trying the example of USB CDC in:https://www.youtube.com/watch?v=rLnQ3W8gmjY&list=PLnMKNibPkDnEEvQWrDqVuu1w_iQ214GXi&index=35It uses the above functions.But when I compile, I get :undefined reference to `USBD_CDC_SetTXBuffer' and to USBD...
I want pass UART_HandleTypeDef *my_huart at function HAL_UART_Transmit and and mange the response with interrupt. The code is show below but doesn't work. Can you help me?//This is myfile.cvoid myfunc(UART_HandleTypeDef *my_huart){ char command[] ...
I generated a USB Host for HID Class with CubeMX, but when I connect a mouse, its LED at the bottom doesn't light up.Debugging through USBH_Process(), phost showed the status as HOST_IDLE and CMD_SEND.To further debug this, I've set the debug level o...
Hi,I've used products in the STM32F4 family, but I have two new projects using the STM32L433 and STM32L432. For both of these projects, I am able to write and verify the flash, however I cannot seem to get the chips to boot from it. They always seem ...
