| Simple controller for AD9850 modules | |
| Uses serial protocol (refer to AD9850 datasheet what pins need to be pulled up/down | |
| Uses library by Elecfreaks http://elecfreaks.com/store/download/datasheet/breakout/DDS/EF_AD9850_library.zip | |
| (for use with chipkit delete that unnecessary line "#include <avr/pgmspace.h>" from .h file) | |
| Fix the pin numbers used to communicate with module | |
| Serial comms - 9600, NewLine (0x0A) denotes end of input, | |
| f 10000 - set frequency | |
| s 20 20000 10 1000 - sweep from frequency to frequency using this step size in that many milliseconds | |
| o 10 10000 5 3000 - oscillating sweep from frequency to frequency and back using this step size in that many ms |
