WebSTM32的HAL库开发系列 – 串口DMA接收. 串口DMA接收函数： HAL_StatusTypeDef HAL_UART_Receive_DMA(UART_HandleTypeDef *huart, uint8_t *pData, uint16_t Size) 串口空闲中断（IDLE）： 当DMA串口接收开始后，DMA通道会不断的将发送来的数据转移到主存，那么问题来了，该如何判断串口接收是否 ... WebAug 10, 2024 · I'm trying to read 8 different single-ended analog signals from an array of op-amps with a STM32H7 MCU, however I only get an array of 8 zeros when using ADC1 with DMA (the readings are recovered via the UART5, but the zeros can also be seen when putting a break point after the ADC buffer is populated).
WebPosted on July 03, 2015 at 21:15 i have the same problem but after a long tracing i found that at the end of dma trans farecompletion the ''hal'' didn't set the state to ''HAL_UART_STATE_READY'' so i set the state to ''HAL_UART_STATE_READY'' at the end ofUART_DMATransmitCplt function in stm32f1xx_hal_uart.c line :1547 and it work ... WebNov 30, 2024 · This repository may give you information about how to read data on UART by using DMA when number of bytes to receive is not known in advance. In STM32 microcontroller family, U (S)ART reception can work in different modes: Polling mode (no DMA, no IRQ): Application must poll for status bits to check if new character has been …
Web再回到串口以DMA的方式发送数据. HAL_UART_Transmit_DMA(&huart1, (uint8_t *)RX1sBuf, sizeof(RX1sBuf)); 此时没有等待时间，这里表示CPU不需要等待串口，在程序后台DMA通道将数据搬运到串口再发送。这里需要注意的是，虽然cpu无须干预，可以继续执行后面的代码，但DMA将数据从 ...
