This project for the ADuC7028 includes two examples: slave.c and slave1.c. Either file can be used with master.c or master1.c * slave.c is receiving data, using bit 4 to monitor the reception. bit 6 in SPICON is cleared. * slave1.c uses the RX interrupts to receive/transmit data. bit 6 in SPICON is cleared. To view either example, only one of the C source files ('slave.c' or 'slave1.c') can be included in the target at any one time. Instructions on how to switch between the two 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 the other 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.
