![]() If no virtual port is shown then then open Device Manager and expand out the “Universal Serial Bus controllers” section as illustrated below. Run the “getSerialPorts” sample program which should show the pad as a virtual serial port: To do this manually select "Update Driver Software" on the "USB Serial Port" right-click menu in Device Manager.Īlternatively the driver can be downloaded from Normally this is done automatically through Windows Update. Or the firmware version (see section 8 below).Įnsure your FTDI driver is up-to-date. If the phrase “DVT sample” or “PVT sample” is not printed on the back of the pad then it must be a fully released version and there should be no need to be concerned about either the manufacture date Any pad showing “DVT sample” should not be used as it will not work correctly. If you have a “PVT sample” pad please make sure that it has a manufacture date of at least Oct 2015 on the back. Listener method for open button, In this method we cover baudrate setting, autoscroll option and connecting to device.STU-430V Installation STU-430V Installation for Serial operation Now we displayed everything as needed, now we can add actions to our buttons. tEnabled(true) //display baudrate selectorĬtEnabled(true) //display autoscrollītEnabled(false) // hide close button (already closed)ītEnabled(false) // hide send buttonĮtEnabled(false) // hide edittext field tEnabled(false) //hide baudrate selectorĬtEnabled(false) // hide autoscrollītEnabled(true) // display close buttonītEnabled(true) // display send buttonĮtEnabled(true) // display edittext fieldītEnabled(true) //display open button SetEnabledUi(false) // not connected to Arduino so false //setEnabledUi method to set UI elements on screenītEnabled(false) //hide open button (already opened) That method takes boolean argument which specifies weather app is connected to Arduino or not Now we can display Required UI elements on screen, I am calling a method to do this MPhysicaloid = new Physicaloid(this) // setting the context for library SpBaud = (Spinner) findViewById(R.id.spBaud) ĬbAutoscroll = (CheckBox)findViewById(R.id.autoscroll) TvRead = (TextView) findViewById(R.id.tvRead) Next, in onCreate method we can initialise those variables we have created btOpen = (Button) findViewById(R.id.btOpen) ītClose = (Button) findViewById(R.id.btClose) ītWrite = (Button) findViewById(R.id.btWrite) ĮtWrite = (EditText) findViewById(R.id.etWrite) Physicaloid mPhysicaloid // initialising library I have attached complete java file Serial_monitor.java first download it and compare it to these small code segments.įirst we have create all our UI elements and library variables Button btOpen, btClose, btWrite Now browse the image file you want and set it as ic_launcher it will override the default android icon Right click on the app > new > image asset ![]() I also added a spinner to select baud rate and auto scroll feature as available in serial monitorĪdded this string array to strings.xml file located in app > src > main > res > values > strings.xml Open – opens the connection to USB deviceĬlose – closes the connection to USB device I have dragged 3 buttons, 1 edit text, 1 text view on to screen then renamed and placed them in correct order. Manifest file is located in App > src > main > AndroidManifest.xmlīy adding that line we are asking permission of the user every time we connect a USB device to OTG portĮditing should be done in “content_serial_monitor.xml” file Manifest file is like main properties file for our project, It contains permissions details and activity details apk file and install it in your phone to communicate with arduino. In this instructable, I will explain how to create an android app that can communicate with Arduino by USB OTG cable, If you dont care about how to just download. ![]() So I decided to make an android app that would send serial data to Arduino to change timings of water motor. So I need a way to change timings without connecting laptop and recompiling Arduino code, that would be complicated for my parents. I haven’t made any user interface for that device to change timings because timings get to change very infrequently. so I made a device to turn on water motor at a fixed timings of day. So I need a portable solution to my problem.Īnother project was, water supply near my place was limited, we get water only at fixed timings. ![]() So, to get the correct value I have to data log the photo resistor reading after fixing the light in place, which was a bit harder, because I cannot leave my laptop outside for data logging for a whole day. I have made an Arduino based night lamp using photo resistor and problem with that is light levels was different from place to place, when I am testing I have used a value as a threshold to switch on the light and after fixing it in its final position that value is way off.
