At some point, you may wish to re-program your ClockTHREE or ClockTHREEjr or maybe you are building a clock from scratch. This post will walk you through the steps.
(Sorry, the formatting is not behaving. Try this file if you are having trouble.)
- Download and install Arduino for your target platform. (More details can be found here.)
- Navigate to the Arduino download site: http://arduino.cc/en/Main/Software
- Download Arduino for your platform.
- Unzip the file to the directory of your choice. (We will refer to whatever directory you choose as <arduino_dir>). I use c:\arduino\ on Windows or /home/justin/arduino/ on Linux so that (for arduino 22 for instance) the path extracted executable is c:\arduino\arduino-0022\arduino.exe on Windows or /home/justin/arduino/arduino-0022/arduino on Linux.
- Download and install ClockTHREE source code
- Download the latest ClockTHREE library source code file from here: http://code.google.com/p/clockthree/downloads/list
- Unzip the library source code file in your home directory. I use “My Documents\sketechbook\” on windows and /home/justin/sketchbook/ on linux. We will refer to the directory you choose as <sketchbook>.
- Point Arduino to your newly extracted library files.
- Start arduino (look here if you have trouble with this step)
- Click File->Preferences to pull up the preferences menu.
- Leave “Use external editor” unchecked if you plan on using Arduino as your editor.
- Click the “Browse” button and navigate to your <sketchbook> directory from step 2.
- Click “OK”.
- Close and restart Arduino
- Click “File->Sketchbook->libraries”. If “ClockTHREE” is listed you’ve done well.
- Using a text editor, edit source code: set compile options and language
- On or about line 55 in the file <sketchbook>/libraries/ClockTHREE/ClockTHREE.h, uncomment (for ClockTHREEJr) or comment out (for ClockTHREE) the following line.
#define CLOCKTHREEJR // uncomment this line for ClockTHREEjr
- On or about line 32 of <sketchbook>/libraries/ClockTHREE/examples/ClockTHREE_02.pde, comment out all but one of the following lines depending on language and hardware.
// #include "english.h" // only need one language at a time // #include "german.h" #include "english_jr.h" // #include "german_jr.h"
- On or about line 292 of <sketchbook>/libraries/ClockTHREE/examples/ClockTHREE_02.pde, comment out all but one of the following lines depending on language and hardware.
// English faceplate = English(); // Only need one at a time // German faceplate = German(); EnglishJr faceplate = EnglishJr(); // GermanJr faceplate = GermanJr();
- Compile and upload
- Connect the FTDI cable to ClockTHREE (mind color labels) and to your computer.
- Click Tools->Boards->Duemilanove
- Select USB port Tools->Serial Port (this may take some trial and error if you have several devices connected).
- Compile and upload <sketchbook>/libraries/ClockTHREE/examples/ClockTHREE_02.pde.
Click the arrow button, second from the right. Right when the black message area at the bottom of the Arduino window displays the message “Binary sketch size:…” click the reset button on ClockTHREE. The timing can be tricky so you may have to experiment.
- Congratulations! That is it. Now you can customize the code to your hearts content!
