GPIB connection to external device using MATLAB
- by hkf
Is there a way to establish a GPIB connection using MATLAB without the instrument control Tool box? (I don't have it). Also is there a way for MATLAB to know what the external device's RS232 parameter values are ( Baud rate, stop bit etc..). For the RS232 connection I have the following code:
% This function is meant to send commands to Potentiostat Model 263A.
% A run includes turning the cell on, reading current for time t1, turning
% the cell off, waiting for time t2.
% t1 is the duration [secs] for which the Potentiostat must run (cell is on)
% t2 is the duration [secs] to on after off
% n is the number of runs
% port is the serial port name such as COM1
function [s] = Potentiostat_control(t1,t2,n)
port = input('type port name such as COM1', 's')
s = serial(port);
set(s,'BaudRate', 9600, 'DataBits', 8, 'Parity', 'even', 'StopBits', 2 ,'Terminator', 'CR/LF');
fopen(s)
%fprintf(s,'RS232?')
disp(['Total runs requested = ' num2str(n)])
disp('i denotes number of runs executed so far..');
for i=1:n
i
%data1 = query(s, '*IDN?')
fprintf(s,'%s','CELL 1'); % sends the command 'CELL 1'
%fprintf(s,'%s','READI');
pause(t1);
fprintf(s,'%s','CELL 0');
%fprintf(s,'%s','CLEAR');
pause(t2);
end
fclose(s)
