Hi I work with stm32f4 modbus tcp /ip.When I connect the ethernet cable first and then power the stm32f4, my code works goodBut, when I first power the stm32f4 and then connect the ethernet cable, I cannot even ping it. How I can solve it? Thanks
Posted on October 22, 2017 at 16:13I want to use ' HAL_UART_Transmit_DMA(); ' to send data in DMA mode like this : char str_Hello[]='Hello\n'; HAL_UART_Transmit_DMA(&huart1,(unsigned char *)str_Hello,strlen(str_Hello)); HAL_Delay(500);But ...
I have been working on a STM32L496VGT6 using a 2GB sd card. I have the interface set to 4bit bus, no flow control and a clock divider of 4. I have a demo application that uses SDMMC, FreeRtos and FatFs and works perfectly. When i move the exact fi...
Hi, I am trying to use the ADC on an STM32G030 for the first time using the low-layer drivers. The terminology of the driver documentation has me baffled as it has nothing in common with the '030 Reference Manual (I have to say the Description of ST...
I am currently developing on a custom board based on the STM32U5 microcontroller with the MX25UM512 NOR flash memory. I am following the example provided by the STM32CubeU5 SDK. The example works correctly when I first run it (so data is written corr...
How can energy harvesting technology be applied to the STM32 Nucleo F302R8 board? My goal is to convert the thermal energy generated during motor operation into electrical energy, thereby reducing energy losses.
Hello,I have to implement a USB CDC device that uses flow control. After a few research it seems to be possible to send a notification SERIAL_STATE that holds the signal DSR in its bitmap.Also, I have found topics on this platform trying to answer th...

Hi, I am writing a driver for the AD5262 digital potentiometer, which uses SPI type serial but requires a 9 bit data format. I would much rather use the HAL SPI library (which has worked on similar AD family pots) and not use bitbanging. However the ...
Hey,I use STM32H745ZI, I want to create an area for shared memory between the cores, I chose AXI SRAM because I need access as fast as possible for the M7 core.The shared memory is intended solely for shared information between the cores.I have two q...
