I came across the STEVAL-EDUKIT01 system and I'm trying to follow the manual downloadable from the ST website but I already have difficulty understanding the equations that govern the inverse pendulum presented in appendix D on page 143 of this manua...

hi, i am working with an example from the book Mastering STM32 written by Carmine Noviello.The example is the 6th of chapter11, it is about Input capture mode.I have a nucleo board STM32F401RE and i am building examples with STM32CUBEIDE tool.I have ...

Hi, in the book i am reading there is an example about UART DMA trasnfer in interrupt mode. In this example i don t understand why the author enables the UART related interrupt.I mean it is not the UART to generate the interrupt but the DMA when tras...

>Are you trying to measure a 50kHz signal using a timer running at 32kHz?yes...then i changed to internal clock for input capture timer, which runs at 84Mz>You want to capture two values, so don't set DMA to circular mode, but to non-circulari have t...

no, you was right first:The reason is that the HAL assumes that the “HAL_UART_IRQHandler()�? routine is properly called to setup internal HAL states. They are mostly related to UART error states (overrun, parity error, etc).

in HAL_UART_Receive_DMA:/* Enable the UART Parity Error Interrupt */ SET_BIT(huart->Instance->CR1, USART_CR1_PEIE); /* Enable the UART Error Interrupt: (Frame error, noise error, overrun error) */ SET_BIT(huart->Instance->CR3, USART_CR3_EIE);

no, i think its becouse HAL_UART_RxCpltCallback is defined weak inside HAL_UART_IRQHandlervoid USART2_IRQHandler(void){ /* USER CODE BEGIN USART2_IRQn 0 */ /* USER CODE END USART2_IRQn 0 */ HAL_UART_IRQHandler(&huart2); /* USER CODE BEGIN USART2_IRQn...

maybe he enables UART interrupt just for error menagement?
