Posted on October 13, 2015 at 10:08Hi, Im using STM32F071RB. For SW certification purpose, I need to get rid of libraries and operate at register level. I modified the init function for USART1 RX in DMA mode: HAL_StatusTypeDef HAL_UART_Init(UART_Han...
Posted on September 30, 2015 at 15:39Hello, im using TMS32F071RB. I would like to use USART peripheral in DMA without using interrupt, but polling at TCIF. Is that possible? Thanks, M #dma-usart
Posted on September 22, 2015 at 17:47Hi, Im using an STM32F071RB. I configured USART to receive data in DMA. I often get reception stuck but I cant understand why. I had a look at the registers: USART1->CR3 looses DMAR bit (0x00001040 becomes 0x00...
Posted on October 13, 2015 at 16:52I have only 1 usart supported by dma. This is my rx procedure: HAL_StatusTypeDef UART_Receive_DMA(UART_HandleTypeDef *huart) { if(huart->State == HAL_UART_STATE_READY)// || (huart->State == HAL_UART_STATE_BUSY_TX)...
