![]() RX means serial data received into the device.The Photon has one † and the Electron has three UART serial ports.Īll of the devices have the Serial1 object, the main UART serial port, on the RX and TX pins. When connecting to an actual serial device, you'll be using one of the UART hardware serial ports. 28800 Listening mode (blinking dark blue).(The device name, cu.usbmodemFD1141 in this example, may be different on your computer.) You can also trigger it by making a USB Serial connection at a specific baud rate.įor example, on the Mac you can use this command to enter DFU mode: Normally you press buttons to enter listening or DFU mode on the Photon or Electron. The commands other then the last two Wi-Fi related commands are also available on the Electron. You can also get into listening mode by holding down SETUP for about 3 seconds until the status LED blinks blue. Listening mode is the default when you plug in a Photon the first time. m - Print MAC Address for the Wi-Fi adapter.L - Safe listen mode (does not run user code concurrently with listening mode).i - Prints the device ID (24 character hexadecimal string).Each of these commands only requires that you type the command letter (case-sensitive): ![]() If the Photon is in listening mode (blinking dark blue), configuration can also be done using the USB Serial port. Tap yes and you should see a screen in the picture above. Open the serial monitor app and it should ask if you want to connect to the device. Install the "Android USB Serial Monitor Lite" application from the Google Play store.Ĭonnect the device to your phone using a USB cable and a USB OTG adapter. If your Android phone supports USB OTG ("on the go") and you have an OTG adapter cable, you may be able to use it for debugging serial! One caveat is that your phone probably won't power up a Photon, so this will probably only work if you have an external power source, like an Electron or Photon with a battery. Screen allows you you both send characters to the Photon or Electron as well as receive them from the USB serial device. Mac - using screenįind the serial port that is being used using the Terminal program command line: This is the configuration screen for PuTTY:Ĭlick Serial (1) then enter the COM port number (2) then click Open (3). It's hard to say what COM port your Photon or Electron will use, but if you open the Windows Device Manager and expand Ports (COM & LPT) it should show the device. Windows - using PuTTY or CoolTermįor Windows, you can also use a program like PuTTY or CoolTerm. You can send data via serial with the Ardiuno IDE as well, but you need to enter text to send in the box at the top of the window and press Return or click Send. Then select Serial Monitor from the Tools menu. Select the port from the Port hierarchical menu in the Tools menu. Note that you can write stuff to the serial port in Particle Dev, but you must do so in the Enter string to send box, it's not like a regular terminal emulator where you type in the same place where stuff is being printed out. Make sure you have the correct port select and click Connect. ![]() Select Show Serial Monitor in the Particle menu if the Serial Monitor is not showing. The Arduino Uno board with an HC-SR94 Ultrasonic Sensor will be used in today’s demonstration.Opening serial monitor for com port: "/dev/cu.usbmodemFD1161" ![]() In this part, I’ll teach you how to utilize CoolTerm to conveniently monitor real-time sensor data. CoolTerm for Arduino Data MonitoringĪrduino is a popular microcontroller platform that communicates through serial port. In this instance, we must utilize a serial terminal such as CoolTerm to evaluate data transmission and reception. This will assist us in ensuring that everything is functioning properly. Serial communication, as opposed to parallel communication (4, 8, or 64-bit), is common in embedded systems because to its inexpensive cost and effective long-distance transmission.Īs makers and engineers, we must occasionally examine the data exchanged between our products and computers. Serial communication is still utilized in many places today. What is the significance of serial communication? Parallel communication, on the other hand, transfers numerous bits at once across a few parallel channels. The fact that data is conveyed one bit at a time across a single channel distinguishes serial communication. Serial communication, as you might expect, is used to send and receive data to and from peripheral devices. CoolTerm is therefore a popular and reasonably priced alternative for those in need of a convenient and effective serial terminal software solution. Roger Meier’s CoolTerm is freeware/donationware that is available for Windows, Mac, and Linux platforms. CoolTerm is an easy-to-use terminal for serial communication with hardware attached to your computer through serial ports.
