Hi, I am working with STM32U585, I read 10 ADC channel which work perfectly on optimization level O0 and O1.but when I set optimization level O2 or O3, I didn't get some channel's value. we got 0 on that channel. Channel which which not work there va...
Hi All,I am integrating the IMU sensor Using I2C DMA in circular mode on stm32f103c8t6 using Hal Library, so facing an issue reading the address value.In the below code "HAL_I2C_STATE_READY " this flag is not resetting after once function executes so...
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...
HiI am in the need to have USB working on the STM32U5G9DK2 board, however I specially do not need ThreadX, so I will configuring USBX in standalone mode. And I do not need to be using UART to complement my sample code as a lot of the sample codes fou...
How can you calculate a CRC-8-ATM using the CRC unit of a STM32F7?I want to check the CRC of the output of an ADC ADS127L11 which is transmitted via SPI. The user manual says the CRC calculation is based on CRC-8-ATM. The output is an 8-bit CRC, and ...
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....
