181214KA. Hello again! Here’s the premise: you hit key on keyboard, robot moves in requested direction. I initially wanted to use the up/down/right/left arrows on they keyboard to control the robot, but those don’t “send” as commands through XTCU, which is the program I’m using to control the XBee hooked up to the computer (thus, the keyboard).
fopen (s) s.BytesAvailable ans = 0 Begin reading data asynchronously from the instrument using readasync . When the read operation is complete, return the data to the MATLAB ® workspace using fscanf . BytesAvailable indicates the number of bytes currently available to be read from the input buffer. The property value is continuously updated as the input buffer is filled, and is set to 0 after the fopen function is issued. You can make use of BytesAvailable only when reading data asynchronously. A bytes-available event occurs when the number of bytes specified by the BytesAvailableFcnCountproperty is available in the input buffer, or after a terminator is read, as determined by the the BytesAvailableFcnModeproperty.

matlab documentation: Using serial ports. Mode 1: Synchronous (Master/Slave) This mode is the simplest one. It correspond to the case where the PC is the Master and the instrument is the slave.The instrument does not send anything to the serial port on it's own, it only replies an answer after being asked a question/command by the Master (the PC, your program).
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.

The following commands in an m-file work as expected when I step through them in the debug mode. However, the transmission stopped immediately when I ran the m-file. The s.BytesAvailable is zero. It looks like the pause command has not properly executed.
meas = fscanf(s) meas = PK2PK Description. You configure BytesAvailableFcn to execute a callback function when a bytes-available event occurs. A bytes-available event occurs when the number of bytes specified by the BytesAvailableFcnCount property is available in the input buffer, or after a terminator is read, as determined by the BytesAvailableFcnMode property. q1 = s.bytesavailable() if q1 == 0 % no bytes available cont = false % restart loop elseif q1 > 0 % bytes available pause(0.5) % wait q2 = s.bytesavailable() % check again if q1 == q2 % same number of bytes as last time? cont = true % exit loop else The following commands in an m-file work as expected when I step through them in the debug mode. However, the transmission stopped immediately when I ran the m-file.

s.BytesAvailable ans = 69 You can return the data to MATLAB using any of the synchronous read functions. However, if you use fgetl , fgets , or fscanf , then you must issue the function twice because there are two terminators stored in the input buffer. This MATLAB function initiates an asynchronous read operation on the serial port object, obj.

Use fscanf to read the measurement type. The operation will complete when the first terminator is read.
