Makefile refactoring:
- avoids recursive call to build with/without main
- takes EXAMPLE parameter. Copies the examples/$(EXAMPLE) folder to projects/$(PROJECT) and $PROJECT defaults to exampleTestProject
- you can now `make run` (TODO: currently re-links, should instead run without linking)

| 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 |
