I have a question regarding GPIO settings for the STM32H743.Does anyone have detailed documentation on the speed of the GPIOx_OSPEEDR register?I would like to know the criteria for using low speed or very high speed.
I've purchased an STM32H7R7L8HxH development board, but I'm not sure how to download a binary file to the external flash. The external flash consists of two W25Q128 chips. The Chip Select (CS) lines of both chips are connected to XSPI1_CS PO0. The ...
Hello ST Community,I'm working on an application using the STM32F103C8T6 microcontroller that implements a Sliding Mode Observer (SMO) and Park/Clarke transformations. I'm facing significant performance challenges due to the computational overhead of...
Hello,I configured QSPI and MDMA in CubeMx and generated the initialization code. I merged the flash demo code (QSPI_ReadWriteDual_DMA), available for the H743 evaluation board, into my project.Regarding the QSPI waveform I'm puzzled whats going on d...
Hello,I am currently working on a project using the STM32 series and have two specific questions regarding MCU selection::keycap_1: Are there any STM32 MCUs that support 5V logic levels for both input and output?Most STM32 MCUs operate at 3.3V logic ...
Hello all,I have a project with ethernet on custom STM32H743 board, ethernet works as expected but only with SYSCLK <= 300 MHz, for sysclk > 300 MHz I get "transmit buffer unavailable" messages.Even when reducing the HCLK, AXI, AHB bus clock, the sys...
Hi everyone: I'm trying to make an application over the NUCLEO U575zi-q, where some GPIO port pins (in this case, GPIO port E) are triggered in a synchronous way with the DAC output, and the values are held in two arrays, one for the DAC values and t...
Hello, I'm trying to use the RTC of my NUCLEO-L476RG including the sub-seconds feature. I've activated the RTC clock source in the .ioc and configured LSE as clock source (32.768KHz). I've set up an initial value to the RTC and I'm reading it out eve...
when I connect to pixhawk with stm32, I want the channel I want to move according to the data coming from the stick. /* USER CODE BEGIN Header */ /** ****************************************************************************** * @file ...
Hi all, attempting to write data to a specific address in flash bank 1 and calculate the CRC. Using three different CRC methods: flash CRC, software CRC, and hardware CRC, but getting three different values for the same data. The code is attached bel...
