Hello sir, I was following your steps but I got an error in the last step.
I created a file in
"bbb_fbc-0.0.2/FB_prussdrv-0.0/libpruio-0.0.2/libpruio/src/c_wrapper" and
named it "bbb-io.c" and pasted the code you wrote. I then created another
file named it "Makefile" and pasted "all: bbb-io.c Makefile
gcc -Wall -o bbb-io bbb-io.c /usr/local/lib/freebasic/fbrt0.o
-lpruio -L"/usr/local/lib/freebasic/" -lfb -lpthread -lprussdrv -ltermcap
-lsupc++ -Wno-unused-variable" in it. after running "make" command, I got
the following:
/usr/bin/ld: cannot find -lncurses
collect2: ld returned 1 exit status
make: *** [all] Error 1
Any ideas how to solve it? I'm running "Linux beaglebone 3.8.13-bone50 #1
SMP Tue May 13 13:24:52 UTC 2014 armv7l GNU/Linux" on my beaglebone black.
I am setting the libpruio library to read from the all the 7 analog pins
with a sampling rate of 40KHz at least for each pin. You're help os
appreciated. Thanks.
