t3andy, Could the IMP handle high quality audio? I would like to wirelessly stream music from a "base station" to a teensy 3.x and output it via the Audio Shield. Thanks

I think I have it backwards. It would be easier to have local storage and use a wifi module to access it rather than stream audio wirelessly. Can the latter be done also?

Hi, I have been messing with the Audio shield for a little bit and now want to dive into wireless transmissions. I have been looking at various rf modules like the Xbee, IMP, and bluetooth modules. The Xbee is not ideal due to its low throughput. I also don't want to use bluetooth as I want...

Your instructions at times can be confusing because some of them are unnecessary for specific applications. For example, I did all the steps as stated in your arduino eclipse plugin instructions as well as the teensy extension file instructions (minus the 'skip to step 9' part). I am...

Figured it out. Put the extension file in the arduino_1.5.2/hardware folder

I did try doing that but the teensy 3.0 does not show up in the list of boards. I also cannot get the right board.txt file in its appropriate place

Ok, I have my first question: How do I upload the blinky example to my teensy 3.0? What (if any) files need to be imported to my workspace? I set my workspace as the same location that my sketches were being saved originally

ahh ok, that is why I thought we made the extension file for. Ive been following the eclipse IDE and plugin V2.2 instructions, hopped over to the extension file instructions after the first 4 steps, then back to plugin instructions up to step 9 and then changed the directories in 'preferences'...

So I chose 1.0.5 but it is saying this plugin is for Arduino 1.5.x and to use V1 of the plugin for earlier versions. Am i missing something? I may have messed up by following the 'install new software' steps instead of going straight to preferences. Should I uninstall the new software from...

I have followed all the steps on your guide and am now in preferences defining the path of the Arduino IDE. I have on my computer 1.0.5 and 1.5.2. In this step should I select version 1.5.2 as the path in my applications folder?

Hi Stevech, I just read through this thread: http://http://forum.pjrc.com/threads/24015-help-with-interrupts-on-t3 It sounds like if I have a serial stream on a data, it is automatically put into a buffer. I then need to parse that buffer for a specific byte. If that byte occurs I need to...

Im thinking I could use one of the ISR() macros to service the interrupt, but how would I trigger the ISF flag in order to execute the ISR?

How do you implement a more complex interrupt? For example, if pin 15 receives 11001110 then the interrupt is triggered. In my case, attachInterrupt is too simple to detect if an interrupt service should be executed.

I have a feeling setting DC high is asserting that pin as the SPI bus and then something in the SPI library "follows" that pin and that is the line transfer is sending its bytes. Is this correct?

If I were to connect the MOSI pin on the controller to say pin 11 on the teensy, how would the library know which pin on the teensy to send the data out? Could you point me to the section of code that takes care of that? I understand the CS is active low and the CLK needs to pause during the...

Questions regarding the Adafruit_ILI9340 library In the following code in the Adafruit_ILI9340.cpp, why does_mosi = _sclk = 0? // Constructor when using hardware SPI. Faster, but must use SPI pins // specific to each board type (e.g. 11,13 for Uno, 51,52 for Mega, etc.)...

If the ILI9340 is the driver for the TM022HDH26 display, how would the ILI9340 library work on the ST7735 controller for a different display?

say you want to put a message on the CAN bus, does the controller automatically frame the message or do you have to write functions/libraries to do so?

Additionally, What would have to be done to make a CAN library?

Hi Paul, I just noticed the 3.1 is CAN enabled. Ive done my research and understand more or less how a CAN network operates. With the CAN controller integrated into teensy, all I would need is a transceiver like the MCP2551/2561 to take the differential signals from the CAN bus and transmit a...

Thanks Paul. I will look into that but I think I may just go with another controller with CAN built in

Paul, Would my next step be to purchase the MCP 2515 and 2551 along with the shield? Then setup a basic network to see if the teensy supports CAN? I am really excited to work on this project

Ok now I understand. There are going to be quite a few inputs and outputs but here are a few: throttle sensor, brake sensor, traction control system, BMS error, Emergency kill switch, ready indicator, battery temperature sensor. Those are the more important ones of a long list. Pretty much...

Thanks for the link! Just to clarify, the shield allows communication between an Arduino and the 2515 controller with SPI interface and the 2551 transceiver? Please bare with me as I am very new to CAN. For each CAN device (sensors, actuators, etc.) there is a host processor that will send...

Teensy as a CAN bus controller Moderator Edit: I've merged the many CAN bus threads and made this topic stick to the top of the Suggestions forum. Current CAN Bus Status (June 2014): Teachop's FlexCAN library works on Teensy 3.1. :) Please use this thread to discuss CAN bus for Teensy 3.1...

Heres a quick video from my phone: http://www.youtube.com/watch?v=ZQLKfoieOjo

I have fixed the issue with one line of code: if (!leds.busy())leds.show(); And now I have a functional visualizer.

Also... I used the serial library to blink the led on the teensy whenever a 'hit' is registered and it worked fine

Completely forgot to post the code! sorry! Processing: void setup(){ String portName = "/dev/tty.usbmodem8061"; myPort = new Serial(this, portName, 57600); } void draw(){ if (bassAvg > 100) myPort.write(1); else myPort.write(0); } Arduino IDE: void loop() { if (Serial.available()) { //...

I have a solid program in Processing doing some spectral analysis. But im getting problems using the serial library to communicate between the arduino IDE/teensy. It takes about a half second to register a 'hit' before the strip lights up. It must be the code I have written to the teensy...

As Quwat said it is a common terminal. I finally took a voltmeter to it. I was very confused by the -V notation. I am also going to connect the +5v directly to the led strip instead of the breadboard due to the large amount of current and heat. I wrote a little sketch in processing to due...

@Quwat How do I feed arrays of bytes to the teensy? can I do it in the arduino IDE?

just put 15 and 16 together and it worked! but it only when i had the same connection, -5v to the ground bus. I had all 240 (4m x 60/m) going but I stopped quickly when I smelled something burning. My breadboard is pretty warm on the supply bus. What do you think of this situation? why might...

I have a 5v 10a switching power supply. I cut the end of a 3 prong surge protector off to connect from an outlet to the supply. I have black to Line, white to Neutral, and green to Ground. I then connect the +5v from the power supply to the +5v terminal on the LED strip. I have tried...

I am struggling just to power this thing. I must be doing something wrong.

Im using the teensyduino. I have a 4 meter long strip and was planning on cutting it into 4 pieces but not until I figured this out. I can use USB to power my lights? Just connect it to Vin?

Oh and theres also a feature that can convert your code into C

Thanks for the links! I am still in school but its summer so I have a lot of time when I get home from my internship. I think I want to get into embedded systems and firmware and stuff. Ive taken one class in C and Ive been using matlab at work and for multiple classes. I have an ar

Im using teensy 3.0 and I soldered some header pins to it and put it on a breadboard. I got the lights running using the neopixel library. I know this is wrong but I have the -5v supply connected to the ground bus on the breadboard and the ground pin from the teensy to the bus. It was the...

I am actually in the process of creating this vector in matlab. You think this is a good idea?

I wish I could help but I dont know enough. Do you suggest any sites or books to get going on well any of this? Like bitbanging and hardware description or communication. I really want to to take the time and learn about this but I feel lost and overwhelmed. I dont really know the...

Has anyone found that connecting the -5v on the ground bus worked to power the ws2811 strips? That was the only way i could get my led strip to work and it only works with adafruits neopixel library. I am having a hard time with power. Can the way i have it hooked up damage my teensy and/or...

Hi all, First post here. Anyways, I would like to sync a strand of addressable led's to music. I know in processing you can use the minim library to do all the audio processing, but where would I begin for the teensy? Thanks, Chad
