Disorganized workspace, organized mind (I hope)

Posted on January 12, 2012 by engineerzero

Today I verified that the Arduino sketch still runs the servos, and then I did some organizing and planning. The note card on the left shows the listing for GIRC control codes (so far). On the right, I wrote out … Continue reading →

PC to Arduino: Serial BOF and EOF control codes

Posted on January 8, 2012 by engineerzero

(First of all, I’ve tried to train myself to refer to the data sent over the serial port as ‘command codes’ but I always find myself lapsing into calling them ‘control codes.’ So I give up for today.) Here’s what … Continue reading →

PC to Arduino: Hello, are you still there?

Posted on January 7, 2012 by engineerzero

I wrote these two sketches to confirm that yes, serial port communication still works between Processing and the Arduino under the new Arduino IDE. The sketch on the left is written in Processing and writes to the serial port. The … Continue reading →

Sending Serial Data from Processing to Arduino

Posted on January 5, 2012 by engineerzero

I want to send data from my laptop to the Arduino-based robot. Processing is running on the laptop and Wiring on the Arduino. In Processing, the serial object is being called ‘myPort’ (it could have been called ‘Joe’ for that … Continue reading →

Arduino Pin 13 as low-res serial monitor

Posted on January 3, 2012 by engineerzero

Now that I have data to send from the computer to the arduino, I’d like to verify that it has gotten to the arduino. My original assumption was that I could echo back the data and read it on the … Continue reading →

GIRC: Reviewing Output in the Processing Console

Posted on January 2, 2012 by engineerzero

After I generate a path and convert the data into turn-and-move format, I want to send the data to the arduino-robot. For this I will use the USB/serial cable. But before I send any data, I want to make sure … Continue reading →

GIRC Distance Commands

Posted on December 31, 2011 by engineerzero

In the above illustration, the first Command Element has a command code of 44, which tells us that it is a Move command, and that we are to move 360 plus whatever is in the second Command Element minus 33. … Continue reading →

GIRC Turn Codes

Posted on December 30, 2011 by engineerzero

Here we make a 76 degree right turn in GIRC, and this information has to be sent over the USB/Serial cable to the microcontroller aboard the robot. This communication is done with a control code pair. As shown, the first … Continue reading →

GIRC Path Data Conversion

Posted on December 29, 2011 by engineerzero

The user inputs path data to GIRC by clicking points on the screen. Processing then draws segments between the points and calculates x,y coordinate data. This data is then converted into distance and turn data which will then be sent … Continue reading →

Five Stages of Programmer’s Grief

Posted on December 28, 2011 by engineerzero

I knew this, but I forgot it yesterday when I was working on GIRC. This convention of inverting the y-axis for screen display isn’t peculiar to Processing, it’s common to many programming languages. There is a way to change the … Continue reading →
