Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
Hello,I'm trying to use both channels of the DAC on STM32L432, but I'm having a very annoying issue: channel 2 only goes up to 0.5V! I think I've configured both channels correctly, because both channels output voltage that changes with my code... b...
I tried upgrading the firmware on the STM32 F446RE board by accessing the usb-dfu. I used DFU-UTIL library for it. But as it turns out, we won't be able to upgrade the firmware using usb-dfu if the code already present on the board has UART or SPI or...
when pwr is down and only vbat is connected. the RTC freeze (TIME STOP) WHEN PWR IS ON IS Continue , please send please send HAL code example stm32f072 configuration thanks
Recently I switched to STM32F767ZI using LAN8742A and the LWIP library. Began to develop a web configurator based on this STM. And there is such a problem. where 192.168.97.200 is a device, 192.168.97.1 is a client (computer).During data transfer to ...
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...
