With the Arduino prepared and plugged into our computer, open CoolTerm and select OPTIONS. Next, download CoolTerm from Roger Meier’s website. I have uploaded a simple sketch from Arduino Project Hub to the Arduino to use the sensor as a rangefinder, and to return the distance detected. Today’s example will involve an Arduino Uno board with a HC-SR94 Ultrasonic Sensor. In this section, I will show you how we can use CoolTerm to easily monitor some sensor data in real time.

#COOLTERM TUTORIAL SERIAL#

How to use CoolTerm to Monitor Arduino DataĪrduino is a popular microcontroller platform that utilises serial port communication. In this case, we have to make use of a serial terminal like CoolTerm to perform tests on data transmitting and receiving. This will help us to ensure that everything is working as expected. Compared to parallel communication (4, 8 or 64-bit), serial communication is popular in embedded systems due to low cost and effective long-distance transmission.įor makers and engineers, we sometimes need to monitor the data that is transmitted between our devices and computer. Serial communication continues to be used all around us today. If you are unfamiliar with serial communication and want to know more, please visit our detailed beginner’s guide – RS232 vs TTL: Beginner Guide to Serial Communication. In contrast, parallel communication sends several bits as a whole, through a few parallel channels. What makes serial communication distinct is that data is sent sequentially one bit at a time through a single channel. What is Serial Communication?Īs you might have guessed, serial communication is used to send and receive data to peripheral devices.

#COOLTERM TUTORIAL SOFTWARE#

This makes CoolTerm a popular and affordable option for users who need a convenient and effective serial terminal software solution.

#COOLTERM TUTORIAL PC#

#include 'mbed.h'īy default, the C stdin, stdout and stderr file handles map to the PC serial connection: #include 'mbed.CoolTerm is a user-friendly terminal for serial communication with hardware that has been connected to your computer via serial ports.ĬoolTerm is freeware/donationware developed by Roger Meier, and is available for Windows / Mac / Linux devices. Tie pins together to see characters echoed back. Pc.printf('Press U to turn LED1 brightness up, D to turn it down ') The pin map of the NUCLEO-F401RE shows LED1 on the Pwm pin. Note: This example only works if LED1 is on the Pwm pin of the board you are using, such as the NUCLEO-F401RE. Use the U and D keys to make LED1 brighter or dimmer Pc.printf('Echoes back to the screen anything you type ') Echo back characters you type #include 'mbed.h'

#COOLTERM TUTORIAL HOW TO#

If you're not sure how to build these examples and run them on your board, please see our build tools section. Use your terminal application to interact with the following examples. If for some reason it doesn't, you can try one of the following:įor low memory devices you may optionally use the ArmMbed minimal printf library. Using terminal applications on LinuxĬoolTerm should work under Linux. Your terminal program is now configured and connected. If you do not see your board, click Re-Scan Peripherals.You should see 9600 baud, 8 bits, 1 stop bit, no parity (9600-8-N-1).If you have more than one board plugged in, you may need to change the port under Options > Serial Port > Port. This opens up an 8-n-1 9600 baud connection to the first available serial port. Some Windows PCs come with Hyperterminal installed.We use it often because it usually 'just works'. CoolTerm - this is the application we use in this example.There are many terminal applications for Windows, including: Serial configuration: The standard setup for the USB serial port is 9600 baud, 8 bits, 1 stop bit, no parity (9600-8-N-1) Installing an application for Windows They provide a window where your Mbed board can print and where you can type characters back to your board. Terminal applications run on your host PC. Specify the internal (USBTX, USBRX) pins to connect to the serial port routed over USB: #include 'mbed.h' Communication over the USB serial port uses the standard serial interface. This program prints a 'Hello World' message that you can view on a terminal application. Communicate with applications and programming languages running on the host PC that can communicate with a serial port.Print out messages to a host PC terminal (useful for debugging).

#COOLTERM TUTORIAL INSTALL#

If you're working on Windows earlier than Windows 10, you might need to install a serial driver. The Arm Mbed microcontroller on your board can communicate with a host PC over the same USB cable that you use for programming. Board to PC communication over USB Board to PC communication over USB
