HiI plan to include the USB input of STM32F303 and am not willing to power up the board with the +5V of Vbus. The board will be supplied permanently with 3.3V. Is it necessary the connection of Vbus? If yes how i should connect it to the +3.3V Vdd of...
I'm working on an STM32L431 and I never be call on HAL_CAN_RxFifo0MsgPendingCallback. I have set a break point in this function but the debugger never stop on it.In my program:I have generated the code using CubeMx and I set NVIC on CAN1: Tx, RX0, RX...
I am failing to get a project based on the STM32L432KC Nucleo32 board to communicate with an Android device via USB VCP.The Nucleo project works fine over USB VCP on Windows and Linux. And a similar STM32L433-based device I made using CDC works fin...
HELLO,I am trying to implement h bridge logic to convert dc to ac but i am not sure about the pin states of complementery pwm once it stop pwm on that and how to use those compl. pwms pins as gpios .what i am actually trying to achieve is run compl p...
Hello! Recently, a stm32 microcontroller came to me and I want to make an http server. On the Internet, looking for projects on stm32 using the lwIP library. But I can not find a multi-user http-server for my device. Some programs after a while begin...
If I make a new project, enable HSE, SWD and USB, compile and flash it, USB works fine. If I then proceed to also enable LSE and use it for RTC, USB breaks. I make literally no other changes than just enabling LSE and setting it as the RTC-source in ...
A brand new Nucleo F767ZI. Plug in USB cable to the ST-LINK usb connection on the board. The Red "com" led comes on steady for about 1/2 sec then begins blinking several times per sec. No other LEDs on. I find the not/pwrEN line from the ST-LINK ...
Hello, i need to develop a board with stm32f103c8t6 mcu wich can communicate with an other stm32f103c8t6 using the usb.I'm studying cdc and i can create a simple program that communicate with laptop through "putty". I can transfer data from pc, recog...
Hallo,My board is the STM32F746ZG Nucleo board.I am using the LWIP_HTTP_SERVER_NETCONN_RTOS example from the stm32cubef7 package.The example works fine initially but if I leave it running for several hours suddenly the board stops responding in any h...
Sorry for my bad englishHi.I use STM32H743ZI and develop firmware.I put an example of a lwip tcp echoserver in my firmware.Example: STM32H743ZI-EVAL lwip tcp echoserver applicationI'm not using RTOS.My question: Ethernet operation relies on build opt...
