I wanted to implement FIR filter and FFT using Cortex M4 in Dual Core STM32H745 Device. Is there any procedure document or application note available to implement by generating from STM32Cube IDE ?Filter Coefficients can be generated from MATLAB filt...
Hi folks,I have a stm32f411 with custom hid running smoothly. But if i change a value in the report descriptor data transmission stops working.I want to change the descriptor cause i want to send more data to the host.Here is the descriptor which wor...
We have been using STM32 L series and F series of micros in our products with STM32Cube Hal drivers , stacks and FreeRTOS. Now we have to go to certified RTOS. Looking at options of SafeRTOS , Azure Threadx , and Flexible Safety RTOS. We would like t...
Hi, I have STM32L496 and use Freertos 10.2. Everything is fine, but I would like read data from queue without removing from the queue. I discovered function xQueuePeek() but I dont know how to use it if I can read specific item from Queue. For examp...
Hi everyone, I am using STM32F429IGTx with ETH/FMC and many other peripherals to construct a control board. There is a special interface that I need to use TIM1/DMA2 driven GPIOs for communicating with another board that need 12 pins. Since FMC and ...
Hi,In my system host mcu update firmware in slave stm32g071cbSome times I found that host controller cannot call embdedded bootloader by pulling up boot0 and reset via pins . After reset always starts main app instead of bootloader. I lost few hours ...
Hello all,I have a strange behavior with the ethernet connection of my STM32F207 application:When I flash the software to the controller the software works. I can ping the controller, I can communicate with a client software to the serversoftware on ...
How can i calculate the speed of microcontroller at what speed it can load data using SDIO 1 bit and also SPI? Can I use SPI to load data into memory card. If yes, do i have to use FATFS library to load ? I have an experience working with SDIO, it us...
I am working on lwip, tcp/ip, RTOS application with stm32f746 discovery board . By clicking a button on the server with html page, i can toggle a LED on the board with the help of the code below:if (recv_err == ERR_OK) { if (netconn_err(con...
