    Hello everyone,
    I am an electrical engineering student in Qatar University and currently I am working on this project, where I need to use hall-effect sensor with high sensitivity, the best I found was Allegro programmable sensor A1362. I am trying to programmer it , I read the whole programming guide but I am still not sure how to do it, especially the part about how to put the sequence which is necessary to put the ICs on the programming mode I though about using MatLab code where I can generate the need it pulses and I wrote this code :
    n_pulses = 8;
    time = 1:1:(40 * n_pulses);
    pulse = ones (1, 40);
    first_pulse = (5.5 * pulse);
    second_pulse = (14 * pulse);
    third_pulse = (26 * pulse);
    total = zeros (size (time));

    total (41:80) = first_pulse;
    total (81:120) = third_pulse;
    total (121:160) = first_pulse;
    total (161:200) = second_pulse;
    total (201:240) = first_pulse;
    total (241:280) = third_pulse;
    total (281:320) = first_pulse;
    figure;
    plot (time, total);
    title ('Pulses');
    xlabel ('Times (sec)');
    ylabel ('Amplitude');

    The plotting part just to be sure it look like the way I need it .
    now I want to know how to apply it on the IC in order to put it in programming mode than start giving it the sequence need it in order to get the highest sensitivity from it any one have any experience or idea how to do it .I would really appreciate… any help .
    Thanks in advance
