I am trying to implement MODBUS-TCP on a TouchGFX generated project. I have successfully enabled Ethernet by following this tutorial on this forum: How to create a project for STM32H7 with Ethernet and LwIP stack working and can ping my board.In the ...
I inherited an old STM32 project (STM32F373) that uses FreeRTOS and the old Standard Peripheral Library (apparently v1.0.0, dated Sept 20, 2012). Among other things, the project uses USART1 with interrupts to receive LIN messages, and also has a task...
I have problems saving data at just under 1Mbit per second to SD, when the SD clock is 25Mbits per second, using the FatFS library. Data is lost, and it is because of the time consumed in performing the ‘f_write’ function for saving data to SD.Could ...
Hi all, We have an STM32H735VGH6 on a custom board with a LAN8742a PHY chip to allow ethernet communication. This custom board is minimally tested so it's possible that there's a hardware issue though I'm uncertain where the issue would be. I gener...
Hello ,I am using STM32H750B(host) device and STM32H743ZI as target board . I am using spi2 from host side and spi1 for target board, after putting my target board in boot mode i am running application from my host device , i can able to see on logic...
Hello all I'm trying to write to the flash memory on an STM32F746 discovery board. This is the code so far, just a test to write a single word.. #define FLASH_USER_START_ADDR 0x080c0000 int Flash_Write(void) { HAL_StatusTypeDef status; u...
I am trying to establish communication between two Nucleo boards (STM32G431RB as master and Nucleo F446RE as slave). I used the example codes from the STM32 GitHub page (NUCLEO-G431RB/Examples/SPI/SPI_FullDuplex_ComPolling_Master and STM32F411RE-Nuc...
Hello everyone, i am trying to configure one STM32H723 as TCP Client and another as TCP Server. I am very new to networking. I used the example project in this github link and didnt change anything except IP addresses and MAC addresses https://github...
I am using open source lwip ethernet connection code and I am cehcking wireshark if i lose any connection. TCP ECHO parts are my true outputs but i was wondering if ARP parts means that my connection is lost and I reconnect or is it just checking gat...
Hi,I noticed there is no Stm32H7 Ethernet PTP example available anywhere. The ST support for PTP is very poor. I wanted to make an example and get it out for review to bring more visibility to the issues with PTP and see if I could solve some issues ...
