hello,
i have sensor which gives voltage output based on number of samples from foot force signal , the voltage signal is in y axis and samples in x axis,
i want it to change the x axis to force signal in matlab code .
plz anyone help.
number of samples are not being changed 90000 samples
i am able to plotting the acquired voltage value against 90000samples .i want the ploting for force signal (N).

hello ..
yes ,I have the foot force signal in matlab,I did not measure anything and I did not do an experiment. I only used the results of the Physion site. Now I have drawn the signal. Voltage according to the number of samples. Now I want to know with what command can I convert this diagram into a force according to the number of samples? What is the relationship between force and voltage for the foot force signal? and I want to know
How can I check the checksum of the force signal binary file? This force signal is measured by a 12-bit adc. I was able to display it through the following method.
fileID1=fopen('control1.let','r');
A= fread(fileID1, [3, 45000], 'uint8')'; % matrix with 3 rows, each 8 bits long, = 2*12bit
fclose(fileID1);
M2H= bitshift(A(:,2), -4);
M1H= bitand(A(:,2), 15);
PRL=bitshift(bitand(A(:,2),8),9); % sign-bit
PRR=bitshift(bitand(A(:,2),128),5); % sign-bit
M( : , 1)= bitshift(M1H,8)+ A(:,1)-PRL;
M( : , 2)= bitshift(M2H,8)+ A(:,3)-PRR;
N1 = reshape(M',[90000,1]); plot(N1);
Can I also check to see if it is correct or not? I do not know what code to use in MATLAB to calculate checksum? Please show me. Thank you.
