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 ... WebMar 22, 2024 · Hi. I’m new to FreeRTOS. Since timing conditions and real time responsitivity were becoming crucial I turned to be using FreeRTOS. I managed to setup a very rudimentary program for an STM32F103 (blue pill) under STM32CubeIDE. Now I’m seeking for a code example that allows for reading one character from a UART Rx register and …
WebNov 23, 2016 · Basically, we have 2 types: TX RX Buffer [] = “AT+something n” pattern corresponds to a answer of the gsm module after a command has been sent. RX_Buffer [] = “r something n” pattern corresponds to a notification of the gsm module. A event flag is set and notified to the OS. A related thread (depending on the buffer patern detected) has ...
