DSP28335DESCRIPTION: .Digital loopback tests for the McBSP peripheral. .Three different serial word sizes can be tested. .Before compiling this project: .* Select the serial word size (8/16/32) by using . the #define statements at the beginning of the code. .This example does not use interrupts. Instead, a polling .method is used to check the receive data. The incoming .data is checked for accuracy. If an error is found the error() .function is called and execution stops. .This program will execute until terminated by the user.
