I am using the STM32F30x_DSP_StdPeriph_Lib_V1.2.3 library following instructions given in stm32f30x_12c.c for the initilization:#define I2C_SHORT_TIMEOUT ((uint32_t)0x1000) #define I2C_LONG_TIMEOUT ((uint32_t) (10 * I2C_SHORT_TIMEOUT)) #define I2Cx_R...
There have been multiple complains in the past about the efficiency of the zero copy RX and TX Ethernet buffer management. But this is not solved in any of the past releases. It is getting very difficult to build a real project out of this. I suspect...
Hi,I use stm32h7 nucleo board and I have been trying to do ethernet communication with udp for a long time.I can ping without to be packet losses.I have only problem is that I can send packet to pc from my board but when I returned to the board from ...
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 ...
