Hello, currently I work at a project where a customized boot-loader for STM32L31 is required.External access for the BL is only possible via I2C interface, where the micro-controller acts as a slave. So far, I've programmed the BL which is placed at ...
Hello,I am trying to write software to send and receive data using I2C - communication between STM and BNO055.I have problem with that my software hangs on loops checking states on BUSY or START flags.Based on: https://www.st.com/en/embedded-softwa...
I've been recommended the G4 or F3 based just on the fact that I'm interested in DSP, but am still trying to narrow things down a bit further, or get a second opinion.One particular project I'm especially interested in is a live audio sampler / loope...
HelloUsing FreeRTOS on F412.Considering this simple function:void initFromEEprom(void) { uint8_t data[10]; HAL_StatusTypeDef err = HAL_I2C_Mem_Read_DMA(&hi2c1, 160, 8, 16, ...
Hi, I'm using CubeMX, Firmware STM32Cube_FW_F4_V1.24.2 with an STM32F411VET (DISCO). When I configure an UART for TX in DMA regular-mode (as opposed to circular-mode), the code in function UART_DMATransmitCplt()in file stm32f4xx_hal_uart.c at line 25...
Hi all,I have used the Ethernet in my custom design board based on STM32H750VB and using STM32CubeIDE with the latest updates. It has an RMII connection to a PHY and I could successfully send UDP packets to the PC both with both polling and interrupt...
Hello,We are using the STM32L4R5 micro controller.As per our need, we want USB MSC and HID class should work in parallel.We have below queries,can we configure the USB MSC and HID class to work them parallel? If yes please provide the guide line.Can ...
Hello,I find in HAL_UART_Transmit_DMA the following code:/* check that tx process is not already ongoing */ if (huart->gstate == HAL_UART_STATE_READY) { ..... return HAL_OK; } else { return HAL_BUSY; }As far as I understand gstate, is for both tx ...
We have an STM32F205RFT6 device that we are trying to get into DFU mode using an HID message over USB.We can get it into DFU mode, but it exits almost immediately. We changed the loading caps on the 8MHz external crystal from 16pF to 10pF and this se...
I have tried setup into device all of kind CA certificates from AWS https://docs.aws.amazon.com/iot/latest/developerguide/server-authentication.htmlfollowin instruction from ST but nothing help!! Only errors:*** AWS connectivity demonstration ***AWS ...
