[PD] pdp: Handling pdp_v4l VS pdp_v4l2 and possibly updating the examples
All the examples in pdp use pdp_v4l.

Anyhow - Maybe the examples for pdp should also exist with pd_v4l2. Or maybe pd_v4l and pd_v4l2 could be encapsulated into, say, an abstraction which enables to chose.

[PD] The final question about Arduino
Hi, At the end, in order to figure out all the weridnesses regarding the apparently different behavior of the Arduino on different platforms, I only need to answer a simple question, well two simple questions: 1. Does the StandardFirmata firmware send the firmware name and version every time it accepts a connection on the serial port, or only when it is powered up or reset? 2. Is the action of opening the connection (i.e. the open message you send in Pd to the [arduino] object) supposed/expected to cause the arduino to reset? This is slightly OT but it is relevant for working with [arduino] in Pd. Thanks m. ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Does the StandardFirmata firmware send the firmware name and version every time it accepts a connection on the serial port, or only when it is powered up or reset? From looking at the code it only sends the digital pins on startup, not the version. Probably it's the Pd patch that asks for the version. 2. Is the action of opening the connection (i.e. the open message you send in Pd to the [arduino] object) supposed/expected to cause the arduino to reset? that might depend on the driver for the FTDI chip, which is different from a regular USB serial connection.

I guess it is this, in Firmata.cpp:
void FirmataClass::begin(long speed)
{
#if defined(__AVR_ATmega128__) // Wiring
Serial.begin((uint32_t)speed);
#else
Serial.begin(speed);
#endif
blinkVersion();
delay(300);
printVersion(); // -- this!
printFirmwareVersion();
}
This function is called at startup.
So, if arduino only sends this at startup, and if startup is not
guaranteed to (re)happen when connecting to it, what is the correct way
to ensure that you send the necessary configuration messages (such as
pinMode stuff) just after opening the port? Other than putting an
arbitrary delay I mean.
If you just send the pinModes immediately after the open messages,
you're almost sure they're lost, but there doesn't seem to be any safe
way to be informed of when you can send them...
Any idea? Or do I have to put a few second delay and hope it is always
enough?
The open 1 message is only triggered by sending the info message,
but then the same problem raises: when do I send the info message?
Thanks
m.

That would ensure you're not talking to the Arduino's bootloader. Opening the port reboots the Arduino. From reading the bootloader code, it does not pass the bytes received before its timeout to the application.
