usart_DMA
- stm32f103利用DMA进行串口数据接收与存储。-stm32f103 use DMA for serial data reception and storage.
GPS_receive_and_DMA
- 通过串口接收GPS的信号,解析出当前的经度和纬度,并使用DMA方式来存储并处理,可以减轻CPU的负担,并且可以使用多样的数据处理方式,以减小误差。-GPS signals received through the serial port, parse out the current latitude and longitude, and the use of the DMA mode to store and handle, can reduce the burden of the CPU, a
ScomTest
- 串口接收GUI(可实时观察数据图像):使用方法 我把STM32 工程里的USER文件放进来了 整个工程太大放不下 连接STM32 ADC1 通道15到外设 把USART1接到电脑上 (程序中在DMA中断发送数据帧头) Matlab 打开GUI serial_communication2 ‘打开串口’ OK 看看数据吧 (有时可能会Matlab报错 关闭再重新执行一次GUI 这BUG一直不知道错在哪)-A serial port receives the GUI can be real-
stm32-chuankou-dma
- stm32 的串口dma数据接收,减轻cpu负担,不需要限制数据长度-stm32 dma serial data receiver, to reduce the burden cpu, no need to limit the length of the data
DMA_for_USART3
- STM32的USART3,通过DMA实现串口数据的接收和发送,接收长度可变,发送长度可变-STM32 USART3, realize serial port through the DMA data receiving and sending, receiving variable length and send the length variable
stm32-Buffer
- stm32f103 通过串口接收数据存在 环形buffer 中, 串口采用DMA方式-Ring buffer, the serial port using DMA mode stm32f103 exist receive data through the serial port
cc1110-no-use-DMA-receive-data
- iar9.3开发环境,cc1110非dam方式实现RF数据接收,可连续接收。带有串口打印功能。-Iar9.3 development environment, CC1110 non dam way to receive data
DMA
- 使用STM32的DMA功能进行串口接收数据,进行了相关的配置,可以很好的理解使用情况-The use of STM32 DMA function to receive serial data, the relevant configuration, you can understand the use of a good
stm32_dma
- stm32 dma 和串口接收大数据的处理(STM32, DMA and serial receive large data processing)
测试程序
- ADUCM360 UART串口学习: UART串口通讯的使用非常广泛,是一个全双工通用异步收发器,兼容工业标准16450,支持DMA。能在串行和并行数据之间可靠的转换。程序的调试常常通过串口发送和接收数据,来修改程序。 异步串行通讯协议包括:a: 5到8比特数据 b:1、2或1.5个停止位,c:无、奇、或偶校验。d:波特率。所有的数据字要求一位起始位和至少一位停止位,产生了支持7至12位范围的字长。(ADUCM360 UART serial learning: UART serial
dma+串口接收
- 无需中断产生,直接使用DMA接收串口的数据,直接下载下来,编译即可,(No need to interrupt, directly use the DMA to receive data from the serial port, download directly, compile it)
UsartHandle
- 该模块实现串口DMA发送中断接收,与系统或者外设通信,一发一答的方式,发送一帧数据,需等待对方应答,如果在规定时间内未等到ACK数据,发送端 会重发该数据,采用状态机制原理,对串口使用以及协议搭建很参考价值(The module DMA send serial interrupt receiving, and system or peripheral communication, one answer, send a frame of data, need to wait for the ans
