Improved readibility of the DIGITAL code in the PRU, using register names instead of aliases and expanding some of the macros, removing unused macros. Binaries were not modified

giuliomoro@28 1 Three simple c scripts can be used to test the network, in conjunction with the basic_network project:
giuliomoro@28 2 udp-client.c, udp-client-sweep.c,d udp-server.c
giuliomoro@28 3 compile them with gcc -o udp-client udp-client.c and similar
giuliomoro@28 4 They can be compiled and run from either the host or the bbb
giuliomoro@28 5
giuliomoro@28 6 usage
giuliomoro@28 7 ./udp-client 192.168.7.2 9998 #sends individual messages to the bbb on port 9998
giuliomoro@28 8 #enter desired values for frequency (and phase).
giuliomoro@28 9 123.0;0;
giuliomoro@28 10
giuliomoro@28 11 The parser is currently very stupid, so the format of the message has to be::
giuliomoro@28 12 frequencyValue;phaseValue;
giuliomoro@28 13 example:
giuliomoro@28 14 700.0;0.1;
giuliomoro@28 15
giuliomoro@28 16 ./udp-client-sweep 192.168.7.2 9998
giuliomoro@28 17 sends messages every 1ms to control the frequency of the oscillator, thus generating a sine sweep
giuliomoro@28 18
giuliomoro@28 19 ./udp-server 9999
giuliomoro@28 20 #will print the info received from BeagleRT with the following format
giuliomoro@28 21 printf("%8d;%.3f;%.3;",gCounter,gFrequency,gPhase);
giuliomoro@28 22 example:
giuliomoro@28 23 88201;700.000;0.123;
giuliomoro@28 24
