| Abstract: | In order to realize the SPI interface protocol between DSP chip TMS320VC5509 and the external serial Flash,the Multichannel Buffered Serial Port(McBSP) was adopted.It used the McBSP of TMS320VC5509 as the master of the SPI protocol,and chose the serial Flash AT25F1024 as the slave,The experiment results show that the system achieved the serial communication between DSP and Flash and also reduce its complexity effetively.The configuration of the McBSP with the CSL library functions routines was also given. |
