![]() Since it does not require an installation and can save the settings to any location, you can also use it from an USB stick. If you need to communicate with other devices by using a COM port, the CoolTerm app can come in handy. A handy app designed to facilitate communication via COM ports Additionally, placing the cursor over a parameter displays a tooltip with a detailed description. While the program is clearly designed for users who know how to send messages through the COM ports, it includes a documentation that aims to familiarize the casual users. If you need to run multiple tests, the app allows you to record the responses to a text document in order to review them later. You can send a string or a text file to the connected hardware in order to view the response. You can change it to hexadecimal view if you feel more comfortable with this reading mode. Microsoft VB extension for serial processing are windows specific though so won’t run on the Mac (which is lucky as this is a security risk). The interface is easy to use and displays the messages received from the device as ASCII characters. He is very lucky to use a Mac and coolTerm works well on the Mac. The messages are neatly displayed in the clean GUI The terminal supports both raw and line mode which enables you to adjust it to various device types. If your device uses a serial port, CoolTerm should be able to send and receive data messages.Īs you probably hinted, before you can use the app you need to configure the connection by specifying the port number, baud rate, parity and other flow control parameters. This application is designed to help both specialists and enthusiasts who use their computer to control various devices such as GPS receivers and servo controllers. ![]() Quick installation, but requires some configuration The program can use the computer serial ports in order to send and receive data. I ran the same code using the same connection configuration and baud rate settings as above on an Arduino Pro Mini (3.3V, 8Mhz w/ ATmega328), and CoolTerm picks up the serial data transmitted from the Arduino Pro Mini just fine (in a continuous stream of values in real time).Īll other things being equal, it seems like the Mega is the only variable creating the delayed serial transmission to CoolTerm.CoolTerm is a compact application that allows you to communicate with various devices by sending messages from a terminal. I’ve ensured that the baud rate settings of my Arduino, the Hairless MIDI Serial Bridge, and CoolTerm are all set to transmit and receive at the same rate (in this example, 57600 baud, 8 data bits, no parity, and 1 stop bit.) In spite of its simplicity, when running this code on my Mega, CoolTerm still displays delayed serial transmissions in irregular bursts. TestVal = value //pure CC value (0-127) for testing purposes If (number = 71) //rotary encoder 'B1' on axiom controller Void ControlViaCC (byte channel, byte number, byte value) ![]() Void HandleControlChange (byte channel, byte number, byte value) MIDI Controller MIDI output -> Hairless MIDI/Serial Bridge -> Arduino Mega -> CoolTermįor testing purposes, I created a much simpler sketch to rule out any other possible issues in my code: #include This is my serial data flow configuration: I originally noticed this when attempting to debug a large sketch wherein I’m configuring my Arduino to receive MIDI data being transmitted from a MIDI controller and use the MIDI signals to control a variety of LEDs, servos, and a stepper motor. CoolTerm seems to be displaying serial data from the Arduino Mega in short bursts every 5 - 15 seconds even though it should be displaying a continuous stream of values every second. (FWIW, I’m running on a Mac - OS 10.9.1). I’m attempting to use CoolTerm as a serial monitor for debugging purposes when working with an Arduino Mega (2560), but have noticed that CoolTerm is not accurately receiving the serial data being transmitted to it from my Mega.
