2812实现SPI的回送测试模式，SPI自发自收，发送和接收采用查询方式实现，将SPISIMO和SPISOMI两个引脚内部短接，实现自发自收模式。SPI将0-99这100个数字逐个发出，然后逐个接收存入Spi_VarRx[]。-2812 to implement the SPI loopback test mode, SPI spontaneous self-closing, send and receive be achieved using query will SPISIMO and SP

dsp28335 spi自测模式 详细设置了28335的SPI模块的寄存器，包括波特率设置，SPICLK的设置，SPISIMO设置。-DSP 28335 SPI LOOPBACK TEST

TMS320VC5509A&CCS3.3 SPI的配置，数字回环，将DR1与DX2相连接可以调试，调试成功-TMS320VC5509A & CCS3.3 SPI configuration, digital loopback, DR1 and DX2 phase connection can debug, debugging success

A SPI-loopBack with interrupt request example code for TMS320F28069.

利用C2000实现SPI通信，并且实现loopback测试(Implementation of SPI communication with C2000 and implementation of loopback test)
