How to Control the Longer BT100-1L Pump via Matlab ?

				
					%%% RUN PUMP 1 CLOCKWISE AT A ROTATING SPEED OF 10 RPM FOR 10s, THEN COUNTER−CLOCKWISE AT A ROTATING SPEED OF 5 RPM FOR 30s BEFORE STOPPING IT

% Open the serial port with the data format corresponding to the BT100-1L
s = serialport('COM6', 1200, 'Parity', 'Even', 'DataBits', 8, 'StopBits', 1);

% Run pump 1 clockwise at a rotating speed of 10 rpm for 10s
Str = 'E9 01 06 58 4C 00 64 01 01 77'; % corresponding control command string
Data = sscanf(Str, '%2x').';
write(s, Data, uint8); % write the Data to the pump

Pumping_time = 10;
while Pumping_time > 0
    pause(1)
    Pumping_time = Pumping_time − 1;
    disp(['Remaining_time:' num2str(Pumping_time)])
end % 10s delay with a visible timer

% Run pump 1 counter-clockwise at a rotating speed of 5 rpm for 30s
Str = 'E9 01 06 58 4C 00 32 01 00 20'; % corresponding control command string
Data = sscanf(Str, '%2x').';
write(s, Data, uint8); % write the Data to the pump

Pumping_time = 30;
while Pumping_time > 0
    pause(1)
    Pumping_time = Pumping_time − 1;
    disp(['Remaining_time:' num2str(Pumping_time)])
end % 30s delay with a visible timer

% Stop the pump
Str = 'E9 01 06 58 4C 00 32 00 00 21'; % corresponding control command string; we took the previous command string and changed the State 1 byte from 01 (start the pump) to 00 (stop the pump) and of course computed the new fcs
Data = sscanf(Str, '%2x').';
write(s, Data, uint8); % write the Data to the pump
