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...
