I purchased the Blend Micro from RedBearLabs. While it is a very nice device, support questions are answered at a low level; even support from Nordic in regards to the bluetooth nRF8001 is very slow & extremely patchy. You should get better support from Texas Instruments (CC2540), I would hope...

I have a Nintendo DS touch screen (4 wire) somewhere. Once I find it, I will test out the absolute positioning (Hopefully within a few days).

@peanutman. I had similar issues. This thread should help you: http://forum.pjrc.com/threads/25722-Teensy-3-1-Logic-Level-5V-tolerance :) Carlos

I just tried with Teensy 3.1 & Arduino 1.0.5 using Teensyduino 1.18. The mouse works as expected for me so far, when I plug in my Teensy 'mouse' it pick up the current mouse position, & does not reset to the centre of the screen. When I plug in a second mouse, both mice continue their positions...

Here are links to two forums I use, If you do a search in their forums for Teensy, you will find lots of useful information of people integrating Teensys into custom keyboards: http://geekhack.org/ - Keyboard Enthusiasts http://deskthority.net/ - Talk, knowledge and expertise regarding...

@onehorse - I remember reading somewhere that most people who got the Teapot demo working did so with Processing 1.5.1.

Thanks onehorse, that works straight out the box with Teensy 3.1. I think I may pick up a Nokia screen, as I see you added output functions too. This link may interest you, a video showing combined/filtered gyro & accel data to help with gyro drift: https://www.youtube.com/watch?v=qmd6CVrlHOM...

@JV88 Using the gy-521 board, I tested the MPU6050_raw.ino from Jeff Rowberg's library example, and can confirm the same issue. Serial monitor returns after disconnecting & reconnecting usb cable to Teensy 3.1: a/g: 0 0 0 0 0 0 I think it is to do with when the device gets initialised...

With the LLC connected, the voltage before the LLC across GND & TP_CLK (TrackPoint CLK) is 4.1V, the voltage after the the LLC is 2.7V. This is when the TrackPoint works, with TP_CLK on Teensy pin 16 (via the LLC). Without the LLC the voltage across GND & TP_CLK is 4.4V, but the TrackPoint...

I have moved over to the pin ranges suggested: Trackpoint trackpoint( 17, //TrackPoint DATA 16, //TrackPoint CLK 14); //RESETBut the TrackPoint doesn't respond (without the Logic Level Converter (LLC)). So I tried removing the LLC from either the DATA or CLOCK, separately. It seems that the...

Here is a diagram, that should help explain what I doing: TrackPoint, Logic Level Converter, Teensy 3.1. :)

I am using a 5V IBM TrackPoint module as a HID mouse. I am connecting the TrackPoint's PS/2 RESET, DATA, and CLK to digital pins 13, 9, 3 via a Logic Level Converter. All works well. The TrackPoint is powered via the Teensy 3.1's 5V VUSB. I am using the GND pin next to the RESET button. I've...

Hello Paul, If some people originally requested absolute positioning, and as many of us now find that relative positioning appears to be more useful. Would it be possible for you to post a fix so that we can use relative mouse positioning (or a hybrid solution), please? At the moment if you use...

Does anyone know why the mouse position get sets to the centre of the screen, when using absolute? Surely if this is because we are now using absolute positioning, and the centre is the initial start position, can't we just add the current XY mouse position to the absolute values on...

So far I have tried connecting the DTR pin from the Bluefruit EZ-Link to the RESET solder pad on the back of the Teensy, hoping that it does the same thing as pressing the button on the Teensy, but no go. Does the reset pin on the back of the Teensy require a special signal in order to put the...

Ok Paul, Thanks to your help I have a working example; so I thought I would report back. I loaded the StandardFirmata example (in Arduino IDE), and uploaded to the Teensy 3.1 board. I tested with your firmata_test app in OSX; and it works. So to get in working with node-red I installed the...

The Firmata_compiled files located here: http://pjrc.com/teensy/td_libs_Firmata.html only contain hex files for Teensy 1.0 2.0 & Teensy++. Can anyone help with Firmata files for Teensy 3.1, please? I am currently using Teensyduino 1.18

Here is a little extra info as to what node-red is: Node-RED is a tool for wiring together hardware devices, APIs and online services; it provides a browser-based flow editor that makes it easy to wire together flows using the wide range of palette of nodes. IBM researchers were looking for a...

I downloaded the node.js installer for osx here (in terminal): http://nodejs.org/dist/v0.10.26/node-v0.10.26.pkg and installed it. With nodejs installed I can run npm commands (in terminal), so now I can install node-red: git clone https://github.com/node-red/node-red.git cd node-red npm...

I am using 1.17 on OSX 10.8.5, and find the same thing as Paul, in that the mouse pointer resets to centre of the screen once, when first plugged in. But if I use Mouse.screenSize(2560, 1440, true) in my sketch, then the mouse will reset more than once. I have a few questions: These lines are...

I have started to add some components here (input devices): http://dev.rootscript.com/hid/ For the moment just a description, product video, data sheet, .ino code, and a schematic. If any one wants to contribute wiring diagrams, updated info, caveats, or Teensy specific code, they would be most...

Also as MichaelMeissner mentioned pins 0,1 & 7,8 are hardware uart serial pins, so pins 5,21 be selectable in code. Maybe someone can confirm.

If you are talking about the greyed out text, I put them in thats way as they were on the original document. As to why they are that way, I'm glad you asked, it was something I was unsure about. The most I could guess, is that these have alternate pin functions, maybe the greys are the default...

@nox771 I have ordered the breakout you suggested (I will be able to use it here or in another project, I have two purple Teensys on the way too):) When you say my "application is single-Master", and talk about "builtin bus multiplexing", I confess I am lost (I will have to study the thread that...

@ stevech I read this somewhere (is this related to buffering the I2C signals due to wire length, that you mentioned?): "I2C is a bus, with multiple slave devices on a single pair of wires. You can chain a number of devices off the same pair of wires, up until you exceed the 400 pF total...

I2C Port Expander - carrier Shield - Teensy 3.1 Project guidance Hello, I am building an aquarium controller/monitor using a Teensy 3.1. I wanted to ask for some general advice before I get my fingers burnt. I am going to use quite a lot of sensors to monitor my marine saltwater tank; here is...

Wow this deal is still going. I just ordered two. As I am new to electronics I have been very cautious about wiring up my Teensy 3.1. Everything here in the UK seems to be double in price to the rest of the world, so getting 2 more Teensy's for the price of one, will stop me from worrying...

Thank you guys for your feedback :) I really wanted to contribute something that would be useful to amateurs who are just starting out with Teensy (like me). @pictographer - Everything looked great on my 27" screen, but after I published to the website, I think I would have to agree with your...

Hello guys, I have been working on a Teensy 3.1 pinout diagram. I have tried to make a little interactive example, in order to get some feedback. Here is a link to version 0.1: external link to Teensy 3.1 Pinout Diagram (Just press the big [Grey] buttons on the example page). Any suggestions...

Hello Steve, So as I understand it, you are saying that it is not possible to upload a sketch to the Teensy via bluetooth, as the "Teensy Protocol" in the Teensy 'Firmware' is only setup to be programmed via a USB serial connection. I was hoping that I may be able to send some 'special signal'...

Hello, I am using a Teensy 3.1, and have connected the RX & TX pins on a Adafruit Bluefruit EZ-Link (Bluetooth module) to Teensy pins 8(TX3) & 7(RX3). DSR & DTR on the EZ-Link are not connected to anything. In the Arduino 1.0.5 IDE, I have selected the Serial Port...
