Dear ST team,we are developing an ethernet based lighting control device using STM32F401 and ENC28J60. presently we are successfully added LWIP2.1.3 , ENC28J60 and implemented TCP function and its working fine but now we want to implement UDP multic...
I use a simple code in stm32 for SD card.The code is written in "int main(void)" section. I am trying to configure a SD card so that as soon as the STM32F750vbt6 turn on, a file is created in the SD card and a text is written in the file.when I turn...
Hello,I use stm32l412b / FreeRTOS.I use below function to display dubug message.The MCU is halted and a watchdog reset occurs when the function below is called in interrupt routie.It works normally if not in interrupt Would you let me know what is...
Hey,I have a problem with reading files larger than size of one sector of FATFs (4096 bytes).Reading seems to be done correctly until it reaches 4096th byte of file, then data is corrupted. The problem appears when one part of readen data is on one s...
hello.The product was developed using STM32L412RB / FREERTOS by two companies.There are apps from two companies using USB CDC.Their PID/VID is the same.Apps from two companies are installed on one phone.Phone is asking which app to use when my devic...
As I use interrupts in my projects a lot, but not every event in the system generates hardware interrupt - I need to be able to wait for events but the waiting needs to be initialized with a hardware interrupt.That means anything called by an interru...
Hello,I have a problem of f_read in the example project FatFS_uSD_Standalone that the function has never been return when trying to read an empty SD cards.The following Pseudocode can access sd successfully in the example project FatFS_uSD_Standalone...
Hello, I am using STM32L031F6 MCU.I have successfully entered into Bootloader mode by connecting Boot0 = High and nBoot1=1. In Flash Loader Demonstrator Target is redable, but the device "STM32L031F6" not listed in Target dropdown. I have attached th...
Hi Team,We are using STM32H743 microcontroller (as a server) interfaced with LAN9353/KSZ8863 with two ethernet ports, one port connected to PC (as 1st client) and another port connected to embedded board(as 2nd client). Till now we are able to check ...
