Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
I use the HAL library function to transmit the wake up command to its I2C address.#define I2C_ADDRESS 0xC0HAL_I2C_Master_Transmit(&hi2c1, I2C_ADDRESS, 0x00, 4, 1000)but my code always return HAL_ERROR and the chip never acknowledges. I'm fairly new t...
Hi I have a project where I have a ST32L433Vx 100 pin 256K memory and 64K ram. I am using a display and as I need a lot of memory I have to upgrade. I am looking for a drop in chip and found the STML452VETx which is 512K and 160K ram. I looked at th...
HelloI'm going to use BLE to make a Bluetooth speaker that is connected to a cell phone.As far as I know, I need to use I2S to use audio output, is there an MCU that supports BLE and I2S communication?And can I know an example or something to refer t...
We have a system with STM32L431CCU which gets its initial firmware through serial download (as described in AN3155). We use USART1 and applied pattern 6 as described in AN2606. The software on the host side (embedded linux system) is either stm32fla...
Dear all,I have an IP Camera which i have interfaced with STM32F767ZI. I m able to command the camera over ethernet (RTSP) and recieve RTP packets containing video data over UDP. Further i wish to interface STM32F767ZI with 2 FIFOs . These FIFOs will...
Hi,I work for Analog devices and presently working to port the software from our hardware to the STM32L4S5ZI. I needed a file that is similar to the attached file which is for our device.Please let me know how to get this file for the STM32L4S5ZI. I ...
Hello!I'm doing an application in which my control board is I2C slave of my PC and my control board has to communicate with another board (let's call it test board) via UART.This test board uses custom UART text commands to perform tests on itself.Fo...
Helllo,I'm trying to communicate with USB module that exposes 3 virtual com ports if used under PC and Windows. It's AT command set based communication module.I'd like to connect to it over USB Host library on STM32F779. I have basic code running, mo...
Hi guys!I need to Burst write multiple values using DMA. The processor that I'm using is stm32F407. I found than the solution for this task is HAL_TIM_DMABurst_MultiWriteStart function, but it is missing in the HAL library. https://github.com/STMicro...
I am using STM32L496 Nucelo, CubeMX 6.1.1; FATFS, DMA SDMMC with FreeRtos. For some reason I have problems when it comes to using DMA2 Channel 4 with FreeRtos. When it is selected for SDMMC1_TX then I can mount SD card and read data without any probl...
