ofxserial's Issues

AbstractTypes.h not found

Compiling the Basic Example under OSX results in the following error:
/Users/xxx/Documents/prj/of_v0.8.0_osx_release/addons/ofxSerial/libs/ofxSerial/include/ofx/IO/SerialDevice.h:32:10: 'ofx/IO/AbstractTypes.h' file not found

"COMx does not exist" codeblocks and windows 8

device.setup(devicesInfo[x], 9600) throws an exception in codeblocks 12 & windows 8: Exception: Specified port, COMx, does not exist.

The port does exist, as it's listed in the previous listDevices() call. Is this a codeblocks issue? I will continue googling.

Send & receive

Im using your library in a project that im working on. I use it to comunicate with an arduino

I have a listenToArdu and a talkToArdu fuctions in of

The issue that im having its that i can not call the two fuctions, if i send i can receive and viceversa

Im using a SeriaDevice objec
Thanks!

macOS 11.13 Big Sur does not show description() is n/a

I used to be able to call ofIsStringInString(deviceDescriptor.description(), "Teensyduino") but since macOS 11.13 the descriptor is n/a.

I will have to dig deeper to figure out why

can't build example_buffered_serial_device against OF 0.9

on Mac OS X 10.10.5 with of 0.9, after updating the example's Xcode project I got this error :

/Users/antoine/dev/of_v0.9.0_osx_release/addons/ofxSerial/libs/ofxSerial/src/SerialDeviceUtils.cpp:51:22: error: no type named 'RegularExpressionException' in namespace 'Poco'
        catch (Poco::RegularExpressionException& exception)

device.send() doesn't work in ofApp::setup() - PacketSerial

Hi,
I'm using this addon for an installation where I'm controlling multiple steppers and servos and it works great if the code where I send the message via serial is inside an event listener function (like mousePressed() or keyPressed() ), but not if I use it inside setup() or update().

To be more precise, this is the code that I'm using to send the osc message via serial (modelled on the OSC-SLIP packet example):

ofxOscMessage osc_message;
osc_message.setAddress("/home");
osc_message.addIntArg(1);

send_osc_bundle(osc_message, cnc_device, 1024);

If I only put these 4 lines inside a ofApp::keyPressed(), it works ok. ✅
If I instead put them inside ofApp::setup() , after setting up the serial device, it does not work. ❌
Finally, if I put them inside ofApp::setup() and also inside ofApp::keyPressed(), even the keyPressed() event doesn't work. ❌

For reference, this is my send_osc_bundle().

//--------------------------------------------------------------
void ofApp::send_osc_bundle(ofxOscMessage &m, ofxIO::SLIPPacketSerialDevice &device, int buffer_size){
    
    // this code comes from ofxOscSender::sendMessage in ofxOscSender.cpp
    // static const int OUTPUT_BUFFER_SIZE = buffer_size;
    char buffer[buffer_size];

    // create the packet stream
    osc::OutboundPacketStream p(buffer, buffer_size);
    
    p << osc::BeginBundleImmediate; // start the bundle
    append_message(m, p);           // add the osc message to the bundle
    p << osc::EndBundle;            // end the bundle
 
    // send to device
    device.send(ofxIO::ByteBuffer(p.Data(), p.Size()));
}

The append_message() is the exact same code of the examples.

Any hint would be great! I've been struggling with this for quite a while.

Thanks!

can't handle errors (app crash) when using packetSerial and usb disconnects (Windows/0.9.8)

hey @bakercp ,
I used the addon and is working really fine! (Windows 10, OF 0.9.8 with ofxSerial master branch).

But when using the packetSerial mode / example, the OF app crashes when disconnected the USB cable. (example_packet_serial and example_SLIPPacketSerial)

I used the other examples templates without packetSerial, and when the cable is disconected the OF app do not crashes. Btw I used to reconnect the serial when the cable is plugged again, and the OF app contiues working fine.

I would like to handle this errors and avoid this crash, because usually the app window can't be closed, and I have to reboot the machine to get it working again.
(I would like to use the packetSerial arduino library, so I don't have to handle the start/finish bytes by hand...)

example_SLIP-OSC/bundleOUT?

Could you provide an example for SLIP/OSC bundleOUT?
Arduino to openFrameworks.

I searched a lot, but I cannot solve this. Please, give me a little hint...

Thanks.

Serial communication not working until opening arduino serial monitor

Dear bakercp,

thank you very much for your awesome work!
I have a problem when using ofxSerial with serial communication to arduino on windows. When plugging arduino it does not work: Arduino is found ("successfully setup COM5…"), but no communication happens. "onSerialBuffer seems to never fire. Trying to send something gives me "IO exeption. Error while writing to the serial port. … |ibs\serial\src\impl\win.cc, line 343."
After opening and closing arduino serial monitor it works without problems.

I can produce the problem on a Computers running Windows 10 with both OF 0.9.8. vs and OF 0.9.4 vs as well as on another Computer running Windows 7 OF 0.9.8 vs. ofxIO is stable branch and ofxSerial is master branch in all three cases.
Ubuntu OF 0.9.4. works without any problem.

It's not completely sure this problem is specific to ofxSerial, still I can reproduce it also in example_buffered_serial_device, while ofSerial example works well.
I'd be happy if you had any advise. I'm ready to do further testing of course.

thanks and have a good day!

cant' make work the example_SLIP-OSC

hey @bakercp , thanks for the addon and the new improvements!

I had errors of out of memory on the Arduino code (using the Arduino IDE ). Then I uploaded the code with the Eclipse Arduino IDE and then upload worked. But the LED do not switch his state.

When the OF app is not linked to Arduino, it hangs blinking like if it was looped on the setup function. When they are linked, nothing happens on Arduino when clicking the OF app. Seems that LEDcontrol function is not called to run...

I am using an Arduino Mega.

packet serial

I want to take a look at the packet serial example, but im not able to make it work.

Im using an arduino mega, uploading just the example, and im running OS X oF0.9, everything compiles and runs ok.

The arduino example also upload to the board without issues, but i see no data coming back from the arduino, onSerialBuffer function never get called.

What can be wrong?

Changing Custom Baudrate

Dear. bakercp

This time it is related to baudrate. I needed 250k speed, so I looked around and fixed it in /home/pi/openFrameworks/addons/ofxSerial/libs/serial/src/impl/unix.cc.

ofxSerial/libs/serial/src/impl/unix.cc

Line 266 in 7a02ff9

#ifdef B256000

#ifdef B250000 //orgin was B256000 case 250000: baud = B250000; break; #endif
But that was not working. and Ive got SerialDevice::setup: IO Exception (95): Operation not supported, file /home/pi/openFrameworks/addons/ofxSerial/libs/serial/src/impl/unix.cc, line 332.`

I am wondering if baudrate is not supported in rpi3 b + or if there is a way to do it.
oFserial can make 250k. Is there any method?

Thanks, and sorry for lower question..

sending data through OSC to 80 servo motors is too big?

Hey@bakercp,
I am making a project which needs to control 80 servo motors (daisy chained) from OF to Arduino, I was trying your 'example_packet_serial_slip', the example didn't work with Arduino Mega but worked with Arduino Uno.
I therefore changed to 'example_SLIP-OSC' as I need to use Mega to control something else as well. It worked with 20 servo motors, however, it will have some sort of unstable data for the servos if I increase the number of the micro servo motors (more than 25). I guess it might be the data I was sending is too big to send via OSC? Any suggestions would be really appreciated.

what example is expected to do ?

There is no description of what example_buffered_serial_device does.
out-of-the-box, it doesn't do anything very exciting... (I'm at 8280052)
but after un-commeting line https://github.com/bakercp/ofxSerial/blob/master/example_buffered_serial_device/src/ofApp.cpp#L145
it does something more interessant :-)

WIN support

Finish writing windows support. Very close. Just need to finish it.

CodeBlocks Win32

I'm having a bit of an issue getting a simple project to compile under codeblock (win32, gcc).

I get the following error:

hello bakercp !
at first, thank you for this great addon.

I can compile example but when I try running, it crashed.

is there anything I missed..?

onSerialBuffer is blocking

I am noticing that when ever I receive a serial signal from my Arduino in

void onSerialBuffer(const ofxIO::SerialBufferEventArgs& args){
}

My app freezes for a split second.

Is there a way to make this event non-blocking?

Thanks for any advice.

Here the whole function:

   void onSerialBuffer(const ofxIO::SerialBufferEventArgs& args){
        // Buffers will show up here when the marker character is found.
        ofLog()<<"serial args.buffer() "<<args.buffer();
        vector<string> splitStr = ofSplitString(args.buffer().toString(), ":");
        
        if(splitStr[0] == "s"){
            //states
            ofLog()<<"serial state:"<<splitStr[1] <<" splitStr[2] "<<splitStr[2];
            if(ofIsStringInString(splitStr[1], "upper")){
                
                upperSwitchState_str = splitStr[2];
                if(splitStr[2] == "ON"){
                    upperSwitchState = true; 
                } else {
                    upperSwitchState = false;
                }
            } else if(ofIsStringInString(splitStr[1], "lower")){
                lowerSwitchState_str = splitStr[2];
                
                if(splitStr[2] == "ON"){
                    lowSwitchState = true; 
                } else {
                    lowSwitchState = false;
                }
                
            }
            
        } else if(splitStr[0] == "i"){
            //info
            ofLog()<<"serial info:"<<splitStr[1];
            
        } else if(splitStr[0] == "a"){
            //alive
            aliveTimer = ofGetElapsedTimef();
            aliveCounter = ofToInt(splitStr[1]);
        } else {
            
        }
        
        
    }
