CAN同样可以进行Loopback测试，我们首先连接一下CAN的基本概念。控制器局域网总线（CAN）作为专为实时应用...
Now it is time to understand which features to use to receive data with UART and DMA to offload CPU. As for the sake of this example, we use memory buffer array of20bytes. DMA will transfer data received from UART to this buffer. Listed are steps to begin. Initial assumption is that ...

ETH_LoopbackMode:回送模式选择,可选使能或禁止,它设定ETH_MACCR寄存器的LM位的值,当设置为1时,使能MAC在MII回送模式下工作。 ETH_Mode:以太网工作模式选择,可选全双工模式或半双工模式,它设定ETH_MACCR寄存器DM位的值。一般选择全双工模式,在使能了自适应功能后该成员设置无效。 ETH_ChecksumOffload:IPv4校验和...

We know that the I2C is a synchronous communication, so both the master and slave should be doing the same thing at the same time. For example, if the slave is sending the 4th bit of the data, then the master should also be looking for the 4th bit of the data. ...
UART common configuration:115200bauds,1stop bit, no-parity DMA RX common configuration: Circular mode,TCandHTevents enabled DMA TX common configuration: Normal mode,TCevent enabled All RX examples implement loop-back functionality. Every character received by UART and transfered by DMA is sent back...
