I have a problem using an action function property in a serial connection with MATLAB. I want to connect the serial port of my computer to a device in interrupt mode (when my computer receives 10 bytes from the serial port, plot this data). 2011-01-14 matlab documentation: Reading from the serial port. Example. Assuming you created the serial port object s as in this example, then % Read one byte data = fread(s, 1); % Read all the bytes, version 1 data = fread(s); % Read all the bytes, version 2 data = fread(s, s.BytesAvailable); % Close the serial port fclose(s); Assuming you created the serial port object s as in this example, then % Read one byte data = fread(s, 1); % Read all the bytes, version 1 data = fread(s); % Read all the bytes, version 2 data = fread(s, s.BytesAvailable); % Close the serial port fclose(s); hello,i am getting this notification when i a using readAll or write () function of QTcpSocket.

You can try flushinput (Serial_Port_obj) function in matlab. This function clears all the data that are stored in the input buffer. Otherwise you can use fread (Serial_Port_obj,Serial_Port_obj.BytesAvailable). The latter just reads instantly all the data stored again in the input buffer.

I think I've published all the details needed. If you need any help with anything, just message me out = fread(s,s.BytesAvailable,'uint8'); Disconnect and clean up - When you no longer need s, you should disconnect it from the instrument, and remove it from memory and from the MATLAB workspace. fclose(s) delete(s) clear s Viewing the Bitmap Data. To view the bitmap data, you should follow these steps: Open a disk file. For measuring the velocity of a projectile, I’m deveveloping a velocity meter. This velocity meter, on which I hope to write some more later on, works by two laser beams that are interrupted sequentially.

By measuring the time in between the interruptions, the (average) velocity can be calculated, as the distance between the laser beams… Read More » Read only when data present You can read out the BytesAvailable-property of the serial object s to know how many bytes are in the buffer ready to be read: bytes = get(s,'BytesAvailable'); % using getter-function bytes = s.BytesAvailable; % using object-oriented-addressing Then you can check the value of bytes to 2008-06-23 2012-03-29 Generated on 2019-Aug-01 from project qtbase revision v5.13.0-1335-gd914a5ba4e Powered by Code Browser 2.1 Generator usage only permitted with license.
