Teensyduino 1.27 Beta #1 Available

Not open for further replies.
Paul: I pulled 1.27b1 down to my Win10 w/IDE 1.6.6 and compiled my recent serial and scrolling and touch examples - No problem.

One Issue with the TOUCH PULL. I'll go issue a new pull request ASAP. <edit: done>

I didn't see this on your merge but "#define Z_THRESHOLD_INT 75" got dropped or I did a bad pull request <edited> missing "#define Z_THRESHOLD 400" - this regularly leads to breaks in the interrupt functionality.

It was a specific fix that helped greatly taking 80 lines of 'sketch' code to 20 when I moved it native to the 'library', made the INT code stable and prevented forced "over reading". Since the interrupt only comes once per touch - any failed touch return (without this 'conditioning' below) prevents future readings [on that 'touch'], i.e. "isrWake = false". 400 is valid minimum for a real touch, but the hardware doesn't have that limitation - a touch is a touch. A light finger on its way to full pressure registers a light initial touch under 400, then ramps up. Likewise a sliding finger may go 'light' of 400 without 'untouching' Once the touch is rejected - the interrupt 'read/update() enable' [i.e. "if (!isrWake) return;"] is distinguished even though the touch never was 'lost' to the hardware to generate a new interrupt.

Admittedly the '75' is arbitrary though worked 100% in my testing after I picked it, and it returns to working as soon as I put code below back As soon as I uploaded the compiled 1.27b1 code I was seeing the failure to sense touch, with the lines below restored so was full functionality.

Code: 
#define Z_THRESHOLD_INT	75

		if (z < Z_THRESHOLD_INT) { //	if ( !touched ) {
			if (255 != tirqPin) isrWake = false;
		}

<edit> On Win10 I've been using 1.6.6 so I decided to try 1.6.7 - TD_1.27b1 then installed properly to that fresh unzipped directory and recent sketches compile.

Is there a reason why this code gets a compile error, it worked with 1.25rc2. Or is this Arduino issue? Using Arduino 1.6.7 an this threads teensyduino for this error.

Code: 
void setup() {
  // put your setup code here, to run once:
}

void loop() {
  // put your main code here, to run repeatedly:
}

#ifdef __cplusplus
extern "C" {
#endif

void test() { 
  Serial.println("test");
  delay(1000);
}

#ifdef __cplusplus
}
#endif
error:

but this works:
Code: 
#ifdef __cplusplus
extern "C" {
#endif

void test() { 
  Serial.println("test");
  delay(1000);
}

#ifdef __cplusplus
}
#endif

void setup() {
  // put your setup code here, to run once:
}

void loop() {
  // put your main code here, to run repeatedly:
}

Also if I get error using the top c linkage code in a new tab.

Yup, they massively changed the build process in Arduino 1.6.7.

Most of the changes are a huge improvement, but automatically extracting function prototypes is still a bunch of tough trade-offs. Obviously ctags isn't very aware of "extern C".

You should probably move this sort of thing into its own .cpp and .h file. Long-term, that's the only way that's likely to keep working with all versions of Arduino.

They updated the mac version this morning. That's a good thing. The mac version they've had for download these last few days has a mysterious difference from the published source code.

I'll prepare 1.27-beta2 soon.

Paul: can you look at including my TouchScreen Interrupt pull (post #2) for beta #2? It seems my weak GitHub skills got you an incomplete version the other week. Without that the int code is inclined to give disappointing results.
 
The multicast support provided by the standard Arduino Ethernet library is missing from the Ethernet library provided by Teensyduino 1.2.7b.
I've updated the EthernetBonjour library to work with Arduino 1.6.6 out of the box and it wold be nice to see this in Teensyduino as well ;-)

I merged a ton of updates to Teensyduino's Ethernet library.

https://github.com/PaulStoffregen/Ethernet

I tested several of the examples and things seem to be working. Some of the API updates I can't really test because none of the examples use them.

I compiled EthernetBonjour's DiscoveringServices example and it's running, but not discovering anything on my network. I'm really not familiar with how it works or what string I need to give it.

Please give this updated Ethernet a try and let me know how it works for you?
 
I've tested the service discovery and it works here.
My network router is an Airport Time Capsule and the Bonjour browser on my iMac shows these Bonjour services to be available:
Screen Shot 2015-12-26 at 10.55.53 PM.png

So if you have the sketch look for _http or _ sbm or _atp it will discover these services.

Code: 
>>Send to /dev/tty.usbmodem451371: "_smb"<<
Discovering services of type '_smb' via Multi-Cast DNS (Bonjour)...
Found: 'Peter's AirPort Time Capsule' at 10.0.1.1, port 445 (TCP)
	txt record: netbios=
Finished discovering services of type _smb

>>Send to /dev/tty.usbmodem451371: "_http"<<
Discovering services of type '_http' via Multi-Cast DNS (Bonjour)...
Found: 'EyeTV Peter Doering’s iMac' at 10.0.1.4, port 2170 (TCP)
	txt record: path=/eyetv/
Finished discovering services of type _http
 
Registering a Bonjour service record, for example an OSC service (_osc._udp) works as well:

Code: 
Connected to /dev/tty.usbmodem451371 at 9600
My MAC is: 04:E9:E5:00:B0:51
Starting Network using DHCP.
My IP is 10.0.1.32
Setting Bonjour Host Name : 04:E9:E5:00:B0:51.local
Bonjour Service Record added successfully


Thanks for adding this!!!

I'm trying this with Arduino 1.6.7 on OS X 10.11.2. When I run the Teensyduino installer and select the Arduino directory the "Next" button of the installer stays ghosted. Clicking on "?", I get:

@Headroom - Any chance you could give my latest edits to Ethernet a try? I don't have any realistic way to test if UDP multicast is working.

https://github.com/PaulStoffregen/Ethernet

Over the last few days, I've made some major changes & optimizations. TCP should be much faster, especially for the case of reading 1 byte at a time.
 
I have not tested intensely, but Bonjour service registration per UDP multicast and OSC protocol per UDP transfer function fine.
This was tested against Arduino 1.6.6 and the Arduino Eclipse plugin as I mainly have stopped working with Arduino IDE.
 
I just tried Arduino 1.6.7 with Teensyduino 1.27 and Paul's new Ethernet library on github and I can't get the EthernetBonjour Library to work at all.
I tried the RegisteringServices example and it doesn't seem to register and I can't ping the device.

Any ideas ?

I do get some warnings when compiling:

Update:
Using the standard Ethernet library in 1.6.7 I could get the library to work but it doesn't seem to work with Paul's latest version.
 
I'm not very familiar with the Bonjour protocol. I do have some Apple devices that use it for network discovery. I also have an Arduino Yun.

Can you give me any hints about how I might use these and examples from that library?
 
@nleclaude, thanks for the help. I'll take a look at the examples and try to test against Arduino 1.6.7 tonight and over the weekend.
I usually don't work with the Arduino IDE but use the Arduino Eclipse IDE (mac user here ;-) so i am oftern a version or more behind in the Arduino IDE.

I have tested service registration successfully with Paul's updated Ethernet library against Arduino 1.6.6 using the Arduino Eclipse IDE but I have not tested it agains the Arduin 1.6.7 IDE.

My standard test rig is a Teensy 3.0 or 3.1 connected to a WIZ820io , which is connected per Ethernet cable to an recent Apple Airport Time Capsule. This I testet successfully with service registration (TCP & UDP) and service discovery.

I've also previously had success registering services connecting a wireless mini router to the WIZ820io but the service discovery did not work in that setup.

The Bonjour browser app is very helpful and is also available for the iPhone I believe..

Testing multicast, Bonjour, mDNS and DNS-SD

I successfully tested two of the 4 examples from the Arduino EthernetBonjour library with Arduino 1.6.7 and Teensyduino 1.27 from the main download here (not from the beta threads from the forum). In both cases I simply loaded the code into the editor and compiled and uploaded to a Teensy 3.1 without any modifications. This tests the two main parts of Bonjour, service Registration via mDNS and service discovery vis DNS-SD.

1. The RegisteringServices.ino registers a _http._tcp service and a little web site called "Arduino Bonjour Webserver Example" shows up in Safari:

Screen Shot 2016-01-11 at 7.48.52 PM.png

When selected it simply displays text: "Hello from a Bonjour-enabled web-server running on your Arduino board!"
It shows up in the Bonjour Browser with the same name.

2. The DiscoverServices.ino attempts to find specific registered services on the network. The Bonjour Browser indicates which services are registered at the moment:

Screen Shot 2016-01-11 at 8.02.57 PM.png

To find these series, once the sketch is compiled and uploaded to the board, open the serial monitor and type one of the device types into the entry line and hit enter. For example "_http" will discover all http services:

Here is a returned result:

Screen Shot 2016-01-11 at 8.00.29 PM.png

It works the same with _smb and _daap:

This hopefully helps to test whether multicast works as expected.
