Not understanding OF to arduino communication

[onurkalaycioglu]

ive looked at the stackoverflow parsing string delimiter thing and im a bit confused. what would a basic arduino sketch for serial.read look like. i found a youtube video that makes more sense, but not enough.

also im getting errors in my OF code, it wants to change mySerial to eSerial and im getting an error of "member reference base type '<anonymous enum at /Applications/Xcode.app..... "

int numBytesWritten = mySerial.writeBytes(outputBuffer.getBinaryBuffer(),

Could you clarify this question with some code ... screenshots or other information? I'm assuming you have seen all of the examples in this repo?

Using ASCII encoded strings:

Using bytes rather than strings:
https://github.com/bakercp/ExperimentalMedia/tree/master/Week6

Also, the video you found does things a slightly different way, so just keep that in mind when comparing.

o i think i completely missed the week 6 simpleserialprotcol sketches. i was going off of this from the assignments page should i not use this code?

// in void setup()
ofSerial mySerial;
mySerial.setup(); // fill in your data

// ...

// in void update()

ofBuffer outputBuffer;

outputBuffer.append(ofToString(VALUE_0));
outputBuffer.append(",");
outputBuffer.append(ofToString(VALUE_1));
outputBuffer.append(",");
outputBuffer.append(ofToString(VALUE_2));
outputBuffer.append("\r\n");

int numBytesWritten = mySerial.writeBytes(outputBuffer.getBinaryBuffer(), outputBuffer.size());

if(numBytesWritten != outputBuffer.size())
{
    // warning ... something probably went wrong ...
}

You can use either one. It depends on what kind of data you want. You can read the code / comments for a clear description of when you would want to use one vs. the other. The week six example just demonstrates another way of doing it (without ASCII encoding).

cool thanks, it works. the week 6 sketches were more of what i was going for. the arduino is ok sending and receiving data simultaneously?

[onurkalaycioglu]

*at receiving

[bakercp]

Yeah, the Arduino can do both at the "same" time. Of course it's not actually happening at the same time, because a Serial.write() will either happen before or after a Serial.read() (and vice versa) in sequence, but it all happens so quickly that it effectively does both at the same time.

ok just making sure its not a damaging process because my "arduino" is a "little" more expensive than a standard board.
