Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
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...
Hello, all. I am currently trying to program a black pill board to print out the output from a sound sensor, for which I use the Arduino IDE 2.3.2. Used components:- STM32F411CEU6 black pill- KY-037 sound sensorCurrent connections:- the "G" pin from ...
Hi,I am using a STM32L452RET6 (without any RTOS) and I would like to use the same timer for both:- drive a sounder on PWM at 4KHz (but ideally also other changing frequencies above and below 1ms time period so it can make more elaborate sounds which)...
Hi,during implementation of a bootloader I have encountered a problem.I'm using stm32 standard peripheral library.During writing to flash, for example at address: 0x0800C000 or 0x08010000 when the 18th line: FLASH_Status FLASH_ProgramWord(uint32_t Ad...
Hi everyone,I have written class that handles U(S)ART communication on top of HAL. In my application I have several objects of that class, e.g. one for USART2, another for LPUART1,...Currently, I have my own way of registering callbacks: I have stati...
Hi all, i decided to write a simple program on my stm32 board (B-L475E-IOT01A), here are some of the setting of my peripheral: i read input data from channel 2 sampling data on rising edge The clock frequency at which the microphone is outputting P...
Hello everyone, thanks for your help.I have a problem regarding the states of inputs that were set exactly the same way.After powering all 10 inputs simultaneously, inputs IN4, IN5, IN6 and IN7 are not in SET, the others are in SET. Relevant data:Usi...
I am using an STM32 Nucleo H563ZI board for stm32CubeIDE and I am trying to send AT commands to a Telit LE910C4-WWX threadx modem over usb using the usbx host and threadx middleware. My program should be able to detect the modem as a cdc acm dev...
Hi,I have an STM32L412RBT6P microcontroller and a CFAG12864T3-NFH LCD which uses an ST7565 controller. I want to use SPI to communicate with the LCD and leverage DMA to efficiently transfer data with lowest current consumption possible. Could someone...
I have a high-resolution timer configured at some frequency. This master timer has three other timers associated to it, where each timer also runs at the same frequency. But the trigger events of these timers are compare values from the master timer,...
Hello @ST Community I am using STM32F769I-disco to save real time data in SD card with SDMMC2 & FATFS. The sensor value are type float. The problem is that there are saving data in the file of SD card but the screen freeze.this is the code that i am ...
