LAUNCHXL-F28069M: lab13b中串口中断函数在哪里啊，没有找到

程序路径：A:\TI\motorware_1_01_00_18\sw\solutions\instaspin_motion\boards\boostxldrv8305_revA\f28x\f2806xM\projects\ccs\proj_lab13b

Green Deng：

你好，lab例程本身是没有SCI通讯的，所以没有串口中断函数。

,

Shaoxiong Guo：

请问怎么便利添加相应的SCI中断及其函数应用呢，C2000 ware中是否由相应的手册或例子呢？  不太熟悉TI的生态系统

,

Green Deng：

C2000WARE中有SCI的例程，你可以参考一下例程：C:\ti\c2000\C2000Ware_3_04_00_00\device_support\f2806x\examples\c28\scia_loopback_interrupts

,

Shaoxiong Guo：

请问上述路径下的scia_loopback和sci_echoback 两个串口通讯例程有什么区别？  光从字面上难以理解什么意思

,

Green Deng：

你可以看一下main函数所在.c文件开头注释中的介绍，里面包含了程序介绍、设置、外部连接、观测口等等很全面的信息。比如Example_2806xSci_Echoback.c中：

//!This test receives and echo-backs data through the SCI-A port.
//!
//!The PC application 'hypterterminal' can be used to view the data
//!from the SCI and to send information to the SCI.Characters received
//!by the SCI port are sent back to the host.
//!
//!\b Running \b the \b Application//!-# Configure hyperterminal:
//!Use the included hyperterminal configuration file SCI_96.ht.
//!To load this configuration in hyperterminal
//!-# Open hyperterminal
//!-# Go to file->open
//!-# Browse to the location of the project and
//!select the SCI_96.ht file.
//!-# Check the COM port.
//!The configuration file is currently setup for COM1.
//!If this is not correct, disconnect (Call->Disconnect)
//!Open the File-Properties dialog and select the correct COM port.
//!-# Connect hyperterminal Call->Call
//!and then start the 2806x SCI echoback program execution.
//!-# The program will print out a greeting and then ask you to
//!enter a character which it will echo back to hyperterminal.
//!
//!\note If you are unable to open the .ht file, you can create//!a new one with the following settings
//!-Find correct COM port
//!-Bits per second = 9600
//!-Date Bits = 8
//!-Parity = None
//!-Stop Bits = 1
//!-Hardware Control = None
//!
//!\b Watch \b Variables \n
//!- \b LoopCount, for the number of characters sent
//!- ErrorCount
//!
//! \b External \b Connections \n
//!Connect the SCI-A port to a PC via a transceiver and cable.
//!- GPIO28 is SCI_A-RXD (Connect to Pin3, PC-TX, of serial DB9 cable)
//!- GPIO29 is SCI_A-TXD (Connect to Pin2, PC-RX, of serial DB9 cable)
