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...
I want to initialise ADC in my FreeRTOS task. If I remove/comment out HAL_ADCEx_Calibration_Start function, put a delay (osDelay(1)) between it and HAL_ADC_Start_DMA or place a breakpoint at HAL_ADC_Start_DMA and pause code execution at it during deb...
Hello, I am trying to setup the CM4 core with lwip+mbedtls working. Actually I get this code working on CM7 but I need to migrate it to CM4. When I run the code the CM4 get a ard fault interrupt. Debuging I can see that this happens in HAL_MPU_Enabl...
Hi Everyone,It was recently recommended to me that I enable DMA2D on my project to possibly alleviate another problem that I'm having detailed here (Weird horizontal artifacts in touchGFX buttons - STMicroelectronics Community). My question is, how d...
Hello!I have a STM32F407VET6 with FreeRTOS continuously receiving data, normally 250-300 characters every 4[ms], by UART+DMA, when it receives a '\n' and idle-line sends the data received to a mailbox(8 mails length). Then a receiver task get one mai...
I'm writing for stm32f417 MCU. The project is generated using STM32CubeMX with firmware package: STM32Cube FW_F4 V1.26.2 (the latest so far).In the USB Host Library there is a file related to HID class:<my_proj_path>\Middlewares\ST\STM32_USB_Host_Lib...
Hi,I have NUCLEO-F411RE and NUCLEO-U575ZI-Q boards. When trying to implement a sine curve with PWM and a low-pass filter I stumbled into problems with HAL_TIM_PWM_Start_DMA.I store the precomputed sine data in an array and call HAL_TIM_PWM_Start_DMA....
Using STM32L452 and HAL version 1.17.2 with FreeRTOS. I'm new to CAN, and am trying to set up a simple one-to-one communication scheme without filters (only two devices on this CANbus talking to each other). I've implemented the RX FIFO message pen...
Hi All,I am struggling with that the maximum DMA buffer size is 64KB. I am currently transferring the data from an ADC to the Buffer using DMA with circular buffering, but I would want the buffer to be around 200KB. I have heard that one can use MDMA...
F. U. I.: I would like to read sensor data from my accelerometer (MPU 6050) with the I²C-protocol.My aim is to present the sensor data on my laptop via /dev/ttyUSB0, but no data reached my USB TO TTL-Adapter.Attached you will find the code snippet an...
Hi I am trying to read a report of USB HID device from my STM32 USB Host code.I am able to read the report descriptor successfully from USBH_HID_GetHIDReportDescriptor call.I wanted to read the 0xD0 report value using if(USBH_HID_GetReport (phost, ...
