![]() ![]() If you are using the Arduino IDE, in the bottom right hand corner of the window will be shown the type of board you are using followed by COM# where # is the number of the port your Arduino is currently set up to use and is also the port you should select within CoolTerm).Īt the same time set the baudrate to 9600 (making sure that in the sketch you have uploaded to your Arduino, you have also included Serial.begin( 9600) in the setup() function.Īssuming that you would like all data to be timestamped (adding the date and time to every line of data sent), do Connection > Options > Receive and check the ‘Add timestamps to received data’ box. When that is done, go into the folder created, and double click on the CoolTerm application.Ĭlick on Connection > Options and then in Serial Port Options select the Port you would like to use. ![]() You will end up with an approximately 10MB zip file which needs to be extracted. (Full details on generating Serial output from an Arduino are available here: Arduino Serial from the official Arduino Reference site.)ĭownload CoolTerm from the link already provided above. There are many software options available, but we typically use CoolTerm (available free of charge here: download CoolTerm) which is a serial monitor which will also capture transmitted data to a text file and automatically add time stamps to each line of data which are essential for a good datalogger.Īs an example we slightly modified the code for our 2016 solar water heating pump controller so that every time data is taken from the two connected digital temperature sensors, those measurements and also the system status (pump ON or OFF) are output through the serial port to a connected PC. However, it is relatively simple to collect data from any number of sensors connected to an Arduino board and send that data over a serial connection directly to a text file on a PC. We make a lot of dataloggers, the majority of which either store data internally and then output a summary to an LCD display, or dump all collected data to an SD card for later processing and analysis on a PC. This is very simple with Linux and Mac OS, but it can be also be achieved on Windows with minimal effort. ![]() I am strongly considering removing Windows XP, installing Linux Ubuntu, and associated Linux versions of LibreOffice, Arduino IDE, and a terminal program.We are often asked how to log data from an Arduinoto a text file saved on a Windows PC. I’ve tried using and after the browsing to the file name, but get the same result – grayed out “OK”, and no data into Calc. I used LibreOffce version 5.0.3.2 because higher versions do not load on Windows XP, and went back to Hyperterminal because of issues with CoolTerm and Windows XP.ĭoes anyone know if there’s a security setting or something like it in Windows XP that prevents LibreOffice Calc from actually using the “Link to External Data” feature to an updating text file? It does not appear to make any difference if the text file is open or closed. ![]() I am currently using Windows 7 Ultimate Service Pack 1 and Windows 10 Home respectively on two other computers with LibreOffice 6.2.7.1 Calc and CoolTerm for Windows, and everything works correctly to log data into LibreOffice Calc. Calc can “see” the text file created by Hyperterminal and set up comma separated columns for data, but when I try to actually use it, the OK is grayed out, no columns are seen, and and of course nothing happens. All programs appear to be functioning correctly independently, however when I use Calc to access data from a Hyperterminal text file that regularly updates, it’s almost like XP does not allow Calc to access the file. I am using Windows XP Professional Service Pack 3, LibreOffice 5.0.3.2 Calc, Hyperterminal, and Arduino Uno to log temperature data. ![]()
