% I'm using a barometer in an arduino where it
% gives me 4 variables.
% I can read in the octave using the code:

%clear;
%pkg load instrument-control
% s1 = serial("/dev/ttyACM0",9600 );
%data = srl_read(s1,3000);
%s1 = char(data)
%...........................................
%Temperatura = 26.90 *C
%Pressao = 94474 Pa
%Altitude = 585.79 metros
%Altitude real = 600.34 metros

%And... i need plot it. How i can store  and plot??

s1 = "Temperatura = 26.90 *C\nPressao = 94474 Pa\nAltitude = 585.79 metros\nAltitude real = 600.34 metros";

s1

[t, p, a, ar] = sscanf(s1, "Temperatura = %f *C\nPressao = %f Pa\nAltitude = %f metros\nAltitude real = %f metros", "C");

outfile = "mydata.dat";
fpwrite = fopen(outfile, "w");
fprintf(fpwrite, "%#5.2f  %#6d  %#6.2f  %#6.2f\n",
                 t, p, a, ar);
printf("%#5.2f  %#6d  %#6.2f  %#6.2f\n",
                 t, p, a, ar);
fflush(fpwrite);
fclose(fpwrite);
