[SCM] uart DL : 0: Also the USART automatically senses the start of transmission of RX line and then inputs the whole byte and when it has the byte it informs you(CPU) to read that data from one of its registers. The USART of AVR is very versatile and can be setup for various different mode as required by your application. In this tutorial I will show you how to configure the USART in a most common configuration and simply send and receive data. Later on I will give you my library of USART that can further ease you work. It will be little complicated (but more useful) as it will have a FIFO buffer and will use interrupt to buffer incoming data so that you are free to anything in your main() code and read the data only when you need. All data is stored into a nice FIFO(first in first out queue) in the RAM by the ISR.

[SCM] Bulkloop DL : 0: 端口环路测试本工程基于CYPRESS的固件程序框架，程序中设置了4个FIFO端点 2个块输出端点：EP2OUT、EP4OUT 2个块输入端点：EP6IN、EP8IN 程序执行时，往EP2OUT/EP4OUT填充数据后将立即通过自动指针传送送到EP6IN/EP8IN端点（未经过外部RAM），来进行批量端点环路测试。打开工程文件加下的cybulk块传输软件，选择对应端点通道（如：OUT:0X02,IN:0X86 ）设置传输数据大小和传送的内容后，点击右边的START按钮便开始端点间的批量传输，SUCCESSFUL框中将显示成功传输的数据量。可通过CyConsole工具软件来验证该例子注意：由于端点均设置成大小512字节的双缓冲结构，往输出端点发送2K(4个512字节)时将填满通道中的空间，再次发送时将出现传送失败。同理，从充满数据的数据管道中读取2K(4个512字节)的数据后，再次进行读取也将出现操作失败。 -CYPRESS
