/* Linux / Windows program to control the frequency of a si570 synthesizer
|
|
ON5GN 6 jan 2012
|
|
Under Linux:
|
|
-use the linux version of function void si570_sleep(int us)
|
|
-compile with
|
|
gcc -Wall -o set_si570_freq set_si570_freq.c -lusb -lm
|
|
-run with sudo ./set_si570_freq
|
|
Under Windows:
|
|
-use the windows version of function void si570_sleep(int us)
|
|
-compile with mingw
|
|
C:\mingw\bin\mingw32-gcc -Wall -o set_si570_freq set_si570_freq.c -lusb -lm
|
|
-run with set_si570_freq.exe
