Greetings.

When I have the time, I will translate each of the sections you mentioned. I currently have an English version of the AX12 Library Manual and the documentation for the XY Motion Control. Once I have finished all sections, I will email them to you! I need a couple more days

Also, thanks for sharing your code with me on this project! It has helped me understand how to transmit bytes between programs and write code more efficiently!

Thanks,
Trey

I added a download link to XY motion control source code, in the ‘downloads’ section. Note that the Arduino code is based on version 2.2 of the AX12 library, which has some differences with the current 2.3 version.

Yes, I’m interested in that English version of the documentation! In fact, I would like to have all my site translated into English, but especially the following:

1) the AX12 library manual version 2.3
2) SAMSA “classic” documentation
3) the article on Speech Recognition
4) the article on Minim 2.02 Palmer Edition

Thank you very much for your insights.

Greetings, P.G.

Thank you! I understand the problem now and I have made the necessary changes to send information between the programs. I now have a working version of a pan/tilt camera with AX12s, but I hope to improve my code.

I have read the documentation you posted many times but still have trouble understanding the method you use to send bytes between the programs. I intend to keep researching this process until I find an efficient way of transmitting data. I would enjoy reading your code to better understand your process and method!!!

I also created an English version of the documentation. If interested I can share or post for your English readers.

Thanks again for sharing your knowledge, I am very appreciative!

You need to implement a little more sophisticated protocol over the serial, for ensure data is properly interpreted. Consider the following points:

1) initialize serial at same speed at both ends (Arduino and Processing). In this case 115200.

2) it’s not possible to send a ‘int’ value through serial, all traffic consist in ‘bytes’, so you need to encode large numbers as several ‘bytes’ and make sure to cast the values ​​that you are sending to ‘byte’.

3) is highly recommended to have a special value that signals the beginning of the message, such as “255″, to prevent read errors.

Look at any example involving communication between Arduino and Processing. If I can, later I post my own code.

Thank you very much for your comments.

P.G.

I use four keys in processing to control the Pan/Tilt direction (Up, down, left, right) and then I send new value to the Arduino. The Arduino receives the data and applies the setPos command to the AX12s. This is where I get an error! Servo moves all the way to the right (looks like position 1024 on the AX12s) I do not know what the Arduino is reading or how I should debug it.

here is my CODE:

#include
#include

NewSoftSerial mySerial(2, 3);

AX12 servoPan;

void setup(){
AX12::init (1000000);
servoPan.id = 5;
servoPan.SRL = 1;
servoPan.torqueOn;
servoPan.setVel(512);
mySerial.begin(115200);
}

void loop(){
if (mySerial.available()){
int serialData = mySerial.read();
servoPan.setPos(serialData);
delay(10);
}
}
_____
In processing:

port.write(motorPan);

where motorPan is an integer and writes the value (ex. 512 or 700 or 353)

If you could help me I will be very thankful! Great site by the way, I’ve learned a lot.
