Hello Everybody, I use STM32CubeIDE1.15.0 Build: 20695_20240315_1429 and a custom board with a STM32303RE inside.I use the IOC interface to set the virtual port com. Everything work fine, just a detail: when i connect, then disconnect and reconnect t...
Hi there,I am working with the Nucleo-H563ZI board. The board is modified so that its hardware can act as a USB host. I am running Azure RTOS with USBx in the board. USBx is configured in host mode (not OTG) with classes HID (keyboard) and Hub. A USB...
I'm facing difficulties bootloading or upgrading firmware on an STM32F405 MCU from an SD card.Could anyone recommend a library or resource for achieving this? I've already tried a few methods but haven't had any success. Any help would be greatly app...
Hello, I am new to STM world. I am trying to make an array of GPIO pin in this format {{PIN1_GPIO_PORT, PIN1_PIN}..... This would then be used in custom function so I can dynamically access this pins. How should I declare such array and how would i...
I am using the STM32U5A9J-DK for a UART communication test, and I expect to display the content sent from the computer's Serial port on the screen (textArea).I'm using UART1, 115200 Baud rate, 8 data bits, 1 stop bits, and I've turned on the UART int...
I got this assembly code (see below) in an ST example code on secure boot and and I don't understand some lines :why do we have to push R1 five times in a row?why is LR set to 0xFFFFFFF9? That is causing a hard fault at runDoes anyone have better un...
Hi, I would like to, trigger an update event interrupt using software. My timer runs in One Pulse mode, the idea is, that another event should also run the code in my Timer ISR. So after this other event happens in my code, I don't want to wait for t...
I'm working on the STM32H747I-DISCO board. While trying out how the recording works on the board, I downloaded and built the latest version 1.11.0 from: https://www.st.com/en/embedded-software/stm32cubeh7.htmlSpecifically, the code in: .\STM32Cube_FW...
Hi,I'm facing problem in reading data from EEPROM, which was written before power cycle.EE_Init() always causes formatting of EEPROM irrespective of EE_CONDITIONAL_ERASE or EE_FORCED_ERASE parameter passed, resulting in erasing the previous dataConfi...
I have implemented a basic I2C between STM32H7 (Main) and STM32F4 (Secondary) processor. I am using an array of size 6 to transmit from the Main CPU to Secondary CPU using I2C in IT mode.The HAL API for I2C requires the data_buffers to be of size uin...
