1 Steps: Observer Calibrator Instruction Manual Download newest Arduino IDE Open file titled OC_Arduino_code inside Arduino IDE For MAC users follow steps 2-5 in comments at top of file (labeled IMPORTANT SETUP STEPS ) IMPORTANT SETUP STEPS: 1.) Add Adafruit_PWMServoDriver Library To add library: Go to Sketch->Include Library->Add.ZIP Library and select the Servo Driver zip file. 2.) Update Arduino IDE for Due compatibility To update: Go to Tools->Board: ->Boards Manager, search for "Due", select the only result and install. 3.) Connect both USB Cables to USB Ports on Computer. 4.) Set Board to "Arduino Due (Native USB Port)". Go to Tools->Board: and select "Arduino Due (Native USB Port)". 5.) Go to Tools->Port and select the "Arduino Due (Native USB Port)". Make note of its communication port for the purposes of updating MATLAB.. Alternatively, for WINDOWS users you can go into device manager on your computer (after plugging in the USB cables) and extract the COM port number for the Native USB Port (listed as Arduino Due under Ports (COM & LPT) ) The communication port I.D. for the Native USB Port will be used to update MATLAB s serial communication command Open MATLAB Ensure that OCGUI.fig is in the same file location as OCGUI.m Open OCGUI.m inside MATLAB Open ledcontrol.m inside MATLAB Open encodercontrol.m inside MATLAB Open automation.m inside MATLAB Update the communication port I.D. (listed as COM30 in the screenshot below) within the files ledcontrol.m and encodercontrol.m Click the tab for the OCGUI.m file so that it is the open file in the MATLAB editor Click the green arrow labeled Run If prompted to add the file to the path, click the Add to Path button

2 The OC GUI should now be open In order to change the brightness level of an LED, either enter an integer number between 0 and 1023 into one of the edit text fields, or manipulate the slider under the edit text field The color of the slider corresponds to the color of the LED being controlled in each array Due to serial transmission delay, changes take time to update. Wait a second in between updating values To have the observer control the LEDs via encoders, click the Observer Control button under the array which you want the observer to control Note: Once the Observer Control button has been selected, the GUI no longer has control over either array and therefore no updates made to the GUI s sliders or text edit fields will be reflected in the arrays The time-out for the encoder control option is 1 hour (3600 seconds), however, this can be changed in encodercontrol.m by altering the number for the time-out variable

3 When the observer is done manipulating the LED array via the encoders, the observer should press the push button to signify a match. When this is done, the results will be exported to MATLAB and exported into a file called results.dat and control of the arrays will be sent back to the GUI Note: Once functionality is given back to the GUI, LEDs are not automatically turned off, therefore zeros need to be inputted into each text field The results.dat file will have the brightness levels of the LEDs as numbers from 0 to 1023, displayed with the left to right order of red, green, blue and white To use the automated test procedure via automation.m: o Create a variable in MATLAB s workspace by right clicking in the workspace window and selecting new o Title the variable whatever you wish and then open it by double clicking on it o Enter the values you want the preset array to be preset with for each run o Each run will be a row of 4 values, with each value being an integer number from 0 to These values from left to right will be the values of the red, green, blue, and white LEDs, respectively o In MATLAB s command window, call the automation function by entering either automation( E, name of variable created earlier) or automation( e, name of variable). The letter specifies which array will be preset. E is the left side array, from the observer s perspective. e is the right side array, from the observer s perspective. o When the automation program is completed, the results will be exported to a file called results.dat with the observer s inputted LED brightness levels listed in the same format as the input variable you created as an input for the automation function FINAL NOTE: OC_Arduino_Code has already been uploaded onto the Arduino Due. If for whatever reason it needs to be re-uploaded to the microcontroller, the process can be done by following steps 1-5 on the OC_Arduino_Code, and then clicking the green arrow at the top of Arduino s IDE, as seen below

4 Observer Calibrator Maintenance Guide A. Manufacturing Additional PCBs An updated (Revision B) PCB design is provided with this documentation. This revision fixes an issue with improper clearances, removing the necessity for manually separating shorts on the PCB. Gerber files, used to submit the design to PCB manufacturers, have been generated for this revision. Advanced Circuits ( was used as the manufacturer of choice for Revision A. The cost is $33 per PCB, and students need not order a minimum quantity of boards. Below is an image of the relevant specifications to select when ordering from Advanced Circuits: B. Editing the PCB Design Editing the PCB design should be done by engineers familiar with physical layout software. The design was completed in Cadsoft Eagle, and original, editable files are provided with this documentation. The software is free, but a paid license is required to edit PCB designs of the size of the OC. C. Swapping Components on the PCB Should the LEDs be replaced on the board with other LEDs of different specifications, the currentlimiting resistor should be updated as well. The correct resistor value can be found via the following equation, where V F and I F can be found from the LED datasheet: R limit = 5 V F I F D. For help with future designs Jeff Lonneville can help with soldering and assembling of PCB boards and Carlos Barrios should be able to help with PCB layout design.
