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 am using an STM32L0XX on a Nucleo-64. I am Trying to communicate with a sensor using SDI12 protocol (1200baud 8-bit even parity).To communicate properly you have to implement a question and answer session. To start with a 2-byte question response...
I use STM32CUBEMX to create code,and when the code is running,I find a problem.My code is stuck at prvCheckTasksWaitingTermination.(stm32f405 + st25ru3993)Simple Description with my system:1,freertos use systick, and HAL use TIM72,two simple task,one...
We are creating updated versions of our products; existing products are based on STM32F411, the new product versions are based on STM32F446.We have previously developed a custom firmware update tool - used for field firmware updates by our customers ...
Using Ubuntu dmesg | grep usb, "device descriptor read/64, error -71" is reported. I am beginning to suspect an issue with the USB CDC for the STM32L082 device. A recent community discussion alluded to a "device triad", class, subclass and protocol, ...
Hi,Is there any issue if in STM32H743ZI, ethernet driver I call:…. SCB_CleanDCache(); SCB_DisableDCache(); HAL_ETH_Transmit(&EthHandle, &TxConfig, ETH_DMA_TRANSMIT_TIMEOUT); SCB_EnableDCache();...so far, it works perfectly until now instead ...
Hi,I never used ethernet before, please excuse my ignorance. II dont want to use lwIP or FreeRTOS. My main goal is to use Ethernet hardware for fast communication between my distanced units. created a project for my 2 piece NUCLEO-H743ZI2 board using...
I want to start PWM DMA on channels 2 and 3 of TIM2, but I've found that it is possible to start only one DMA per timer. My MCU is stm32f103 series and my code is:HAL_TIM_PWM_Start_DMA(&htim2, TIM_CHANNEL_2, (uint32_t*)&send_buff_one , 16); HAL_TIM_P...
Hello there,the GCC version of the startup_stm32l412xx.s included in STM32Cube_FW_L4_V1.14.0 is missing the USB interrupt handler. It's supposed to go right after LPTIM2_IRQHandler: .word LPTIM2_IRQHandler .word USB_IRQHandler .word DMA2_Channel6_I...
Is: #define TIM_RESET_CAPTUREPOLARITY(__HANDLE__, __CHANNEL__) \ (((__CHANNEL__) == TIM_CHANNEL_1) ? ((__HANDLE__)->Instance->CCER &= ~(TIM_CCER_CC1P | TIM_CCER_CC1NP))) :\ ((__CHANNEL__) == TIM_CHANNEL_2) ? ((__HANDLE__)->Instance->CCER &= ~(TI...
Hello guys,I am trying to understand RTOS Kernel and create a simple one ,for that I am using core registers and I have a problem in asm codes.I am following UDEMY course so teacher is using Cortex M4 but because of free I am using Cortex M0 probably...
