ADC and DMA

Hi,I'm using ADC1 in combination with DMA (One-Shot-Mode). The ADC is used read out a spectrometer (288 pixel). Starting the read function does the following procedure:HAL_ADC_Start_DMA( &hadc1, buffer, 288);Wait for callback: HAL_ADC_ConvCpltCallbac...

I tried to implement TCP server echo - ethernet program in stm32f207zg nucleo board using stm32cube. It is implemented using LWIP library but it is not working. Please give me any solution.

(SOLVED) Timer Interrupt only do the first if statement

Hi everyone!I had a problem with timer interrupt. When i use 2 if statements in timer interrupt it't only do one of them. My if statements are in different condition.Here brief of my codevoid HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef *htim){ if...

STM32 Usb Mass Storage EJECT issue

I have Usb Mass Storage working well on my custom board device featuring an STM32F469AIH6 and an eMMC (SDINBDG4-8G). I can connect to either a Mac or Windows machine and the device shows up in the Finder/Explorer and you can read/write files just fi...

Pin initialization defect on Nucleo F767ZI

In LwIP HTTP server demo, ethernetif.c, HAL_ETH_MspInit():...  /* Output HSE clock (25MHz) on MCO pin (PA8) to clock the PHY */  HAL_RCC_MCOConfig(RCC_MCO1, RCC_MCO1SOURCE_PLLCLK, RCC_MCODIV_4);...According to the schematic, this pin is the USB SOF i...

Creating custom HTML pages with lwip LL drivers and application projects

Hi, I have gotten the LL examples included in the STM32F$ firmware package to work on my computer and I am able to open the provided web pages for the ADC SSI and the LED CGI. My question now is how do I include a custom HTML page into this website? ...

PLL initialization defect on Nucleo F767ZI

In main.c, SystemClock_Config(), the PLL is set up as follows:... RCC_OscInitStruct.PLL.PLLM = 25; RCC_OscInitStruct.PLL.PLLN = 400;  ... RCC_OscInitStruct.PLL.PLLP = RCC_PLLP_DIV2;...The implication is that the clock is 25MHz, and being divided down...

while using I2C, there's any problem if one of the register has the same address than the device ?

Hello !i'm using I2C communication between a Nucleo-STM32F401RE board and a camera in which there a PIC16F1847 MCU. the application is about to write three bytes in a register in order to make a focus adjustmentthe thing is, the device address is 0x3...

Ethernet stopped working after migrating to STM32F457IG MCU from STM3240G-EVAL Board

Hi!I have a working ethernet code on my STM3240G-EVAL Board with STM32F457IG MCU. By working i mean MCU responds my ping requests. I'm using FreeRTOS and of course LwIP. And now i want migrate to my own PCB with STM32F407ZG6 MCU. When I connect a DP8...
