The SPI project demonstrates SPI communication using two Analog Devices ADuC703x Evaluation Board. it includes 4 different files: slave - demonstrate the basic SPI configuration in slave mode slave1 - demonstrates the use of interruption in slave mode master - demonstrate the basic SPI configuration in master mode master1 - is a interrupt driven SPI example for master mode configuration To compile any of these examples, only one of the C source files ('slave.c' or 'slave1.c' or 'master.c' or 'master1.c') can be included in the target at any one time. Instructions on how to switch between examples are as follows: * In the Project Workspace window, right click on the active source file in the 'C Source File' folder. * Select ' Options for 'NAME_OF_FILE.c' '. * Uncheck the 'Include in Target Build' box * Click OK. * To activate another file, right click on it in the 'C Source File' folder in the Project Workspace window. * Select ' Options for 'NAME_OF_FILE.c' '. * Check the 'Include in Target Build' box * Click OK. * Compile and run as normal.
