Does the Linux-side offer any services to easily access Key/Value-DB's or processes like the Arduino-Yun Bridge does?

Hi Under https://www.pjrc.com/teensy/troubleshoot.htmlit is noted that every teensy has a special VID/PID. Is there a list somewhere for reference? Thank you, Dani

Thank you for the answer, I'm so impressed with what happens behind the curtains. I think, the teensyloader is the best way to upload code for the moment!

Michael, thank you very much for your detailed ideas – I just ordered some of them to give them a try.

Hi Paul, hi everybody I've been using a Teensy - hardware serial - RPi - setup using Mattias Schlenkers "nuage" for a while (http://www.arduino-hausautomation.de/nuage/). It works very well. It would be very interesting though to be able to program the teensy using hardware serial. Is that...

Thanks for mentioning the ESP8266 – I like that one too – bot only for certain applications. What I like about the setup with the Pi ist the ability to use a real webserver and the Bridge which includes the JSON data storage, the mailbox, the ability to fire shellscripts, use wget or curl...

For the record: At the moment, my favorite alternative to the Arduino Yun is a Teensy 3.5 with a Raspberry Pi 3 (because of the included WIFI), connected over Serial1 using Mattias Schlenkers «nuage» (http://www.arduino-hausautomation.de/nuage/) and Paul Stoffregens generalized Bridge...

Hi Paul, hi everybody I have been teaching begginers classes called «web of things / robotics» for the last two years using Arduino Yuns. I'm teaching 18/19 year old students. I'm not very happy with the yun, because it is badly and inconsistently documented and the AR9331 with it's bridge is...

By mistake, I gave A10 5V - and the pin seems to be alright. Given 5V, it returns 1023 to analogRead(A10) which is ok with me. Will the pin «break» over time? Thanks for clearing the electronics behind analog only pin A10. Dani

Nuage works quite well with a Raspberry Pi 3 and a teensy 3.1 using Serial1. Of course teensy 3.1 cannot be (re)programmed over Serial1. Would it maybe be possible to reprogram one of the newer Teensies (3.5/3.6) over serial, so that the combination of the two systems would be a real alternative...

Of course it's not windows but probably even less stable since I've programmed it! I generally find it a good idea to be able to reset a microcontroller - it will probably get stuck where you've expected it the least. Thank you for your code, but I want to be able to reset it by button. As far...

I have an installation that includes a Raspberry Pi and a Teensy 3.1. They share a power supply. I want to be able to reset the teensy from the outside of the casing without having to cut the power (because the RPi would suffer from a sudden power loss).

Did I get this correctly from the discussion: The best way to reset a teensy 3.1 into the user program is to take RESET to Ground? Too bad it is so hard to reach. Thanks for confirming it. Dani

Thanks! A also like Ctrl-A and then :hardcopy -h <filename> to save a transcript of all received bytes. Dani

Great, thank you very much. To conclude: stty -F /dev/ttyACM0 cs8 57600 ignbrk -brkint -icrnl -imaxbel -opost -onlcr -isig -icanon -iexten -echo -echoe -echok -echoctl -echoke noflsh -ixon -crtscts & followed by screen /dev/ttyACM0 gives me a great monitor to look at USB-Serial of the teensy...

Hi I have successfully installed teensy_loader_cli on a debian jessie machine to upload .hex-files to a USB-connected teensy 3.1. I would like to be able to «listen» on that USB serial port similar to the «Monitor» in the Arduino IDE. According to...

Does anyone know if a teensy 3.1 will be damaged if 5V is applied to a pin if the teensy has not been powered? What about applying 5V while it is being powered up? Thank you, Dani

Thanks for you replies. At the moment, I don't dare trying many more things with my relay. I ordered one of the pololu switches mentioned above (https://www.pololu.com/product/750) and will work from there. And I've started to look for a simple digital oscilloscope (I'm now waiting for a Rigol...

Indeed, I'm trying to do something like the pololu-product - but tried to invent it myself (with things I hat at hand) (with obviously no luck). Interestingly the circuit worked for quite some time while I had no other consumers as a led. The trouble started, when I added more load (like the...

Well here are my schematics (I just cut the Vin-USBpower connection but yet fried and lost my fourth and last teensy 3.1, I'm devastated). The machines startup is initiated by pressing the power button, which turns the relay on and hence the teensy is powered. As soon as the teensy is running...

Is there any change to rescue the chips?

Thank you! I should have asked before ... But out of curiosity: What did actually happen to my fried teensies? How will the setup behave differently once VIN is seperated from USB power?

Hi guys I'm frustrated because I just fried my third teensy 3.1 and still don't know, what happened (at least I have an idea). Every time one broke it took me a while to realize that the teensy was fried (when powered it get's very hot, isn't registered by the system anymore and it can't be...

Hi, I tried to use pin 8 as an input. It worked well, as long as I didn't start any SPI-communication. From that moment on, all I ever got, was a high on that input. I measured 1.635V which made me think that it could be the mean of normal SPI chattering (0 V - 3.3 V). On the pin out card, pin...

Great! I added some resistors (100 ohm, I had done it before I heard about the 200 ohms) to the MISO and the SCK pins (close to the source of the signal), reduced the clock frequency by factor 2 and now it works! THANK YOU VERY MUCH. Since I have already soldered so much - I'll stick to my...

The beaviour of the setup at the moment is as follows: When I unplug the SD card I can use all seven displays without problems. When I unplug the displays from the wirenet, I can access the connected SD using SDFAT library without problems. Connecing two or three displays and the SD card, I can...

The lengths of the wires (I try to connect 9 devices) differ from about 10cm to about 65cm. I'll try with 100ohm, but am interested - let's say it still doesn't work: how would I check the influence of the resistors - would I have to use an oscilloscope? Might I have to use different resistor...

Hi In https://www.pjrc.com/teensy/td_libs_SPI.html#ss Paul mentiones 100 ohm resistors to be placed between the teensy pin and the long wire. Is that important for all SCK, MOSI, MISO and SS cables? Simply in series with the cable? Thank you for your advice, Dani

Hi all I'm still stumbeling over issues with using the Ethernet Shield with SD-card with teensy 3.1 and dare asking another question. I'm not completely sure I read the teensy 3.1 pinout correctly concerning the SPI bus. I have connected seven RA8875 displays using SPI. I tri-state their...

You saved my day. Partially. Thank you. Setting only the INPUT_PULLUPs enabled only the ethernet-test (code see above) dispite inserted SD card. With additional physical 10k pullup-resistors, the SdFat SdInfo-sketch started to work as well. BUT: When trying to read different SD cards using the...

That is right - I remapped it to 9 (I tried it with 4 as well - same result).

Teensy 3.1 and ethernet shield: Ethernet only working as long there is no SD card Hi all I'm trying to use an official ethernet shield (R3, with W5100) with a teensy 3.1 (using pin 10 as W5100-CS). Ethernet runs well by itself. But I run into trouble as soon as I insert (!) an SD card into it's...

Guys! In the light of the RPi getting faster and faster (http://thepihut.com/blogs/raspberry-pi-roundup/16970168-raspberry-pi-2-vs-model-b?mc_cid=1ca958643b&mc_eid=098a4792a9) (but with still only two SPI-ports), wouldn't it be sooo cool to be able to use it with a teensy using the bridge?! Has...

Connecting a Teensy 3.1 to an Arduino YUN using USB and the bridge I tried to connect the teensy 3.1 over USB to an Arduino Yun. I thought that maybe that would make for a faster bridge than over UART. Therefore I replaced the original run-bridge with Paul's run-bridge from Github...

Today, I connected the teensy 3.1 to a «real» debian (running an a laptop called ibm). Again connecting the devices over USB. The debian has Paul's Bridge running. This system however gave more information over syslog when connecting: Dec 28 00:27:27 ibm kernel: [ 6510.824074] usb 3-1: new...

Hi Paul! Have you, by any chance, had a moment to let the teensy 3.1 try to talk to your new raspberry pi? Best regards, Dani

Oh, how could I have forgotten that. Thanks for pointing that our! Dani

Hi I'm using a teensy 3.1 to drive three TFT's over (hardware-line-driven) SPI. That works like a charm. However, to my device, I have also a pushbutton attached (with 10k pullup resistor), connected to pin 16. However, when running the following code, digitalRead(16) always returns 0...

Listening to SerialUSB of teensy connected to RPi (with bridge) over USB. I'm a step further. When I use the following script to see what happens at Serial (USB), I get the response below. Script:void setup() { // put your setup code here, to run once: Serial.begin(9600)...

I tried root@pi:~# /sbin/getty -8 -c -L -a root 9600 ttyACM0 and root@pi:~# /sbin/getty -8 -c -L -a root 9600 /dev/ttyACM0 No difference on the teensy 3.1 side: Hanging at «Trying to start bridge». Is there a way to output what's happening over Serial on the Serial1-Arduino-IDE-Serial-Monitor?

Thanks, so that's not it and getty should be listening. Still I have the Bridge.begin(Serial); not returning.

Could there be something wrong with the code of /usr/bin/run-bridge-udev towards it's end: When adding a write-out to: DEV=${DEVNAME##*/} echo DEV > /tmp/dev.txt (while test -w $DEVNAME; do /sbin/getty -8 -c -L -a root $baud $DEV done) & All it says in /tmp/dev.txt is «DEV». And then in...

First try USB-Bridge between teensy 3.1 and RPi (jessie) I found some time to play: I installed the newest Bridge on my Arduino IDE 1.0.6, installed the bridgeclient on the RPi (running jessie) as described on github. I also connected a FTDI-cable to have at least some output from the teensy...

That is so cool! Unfortunately, I'm very (like day and night) busy this week with my payjobs - but I'll give it a thorough try as soon as I can! Thanks already! Dani

There seems to be a lot of work ... please only invest time if you yourself are interested in the porting as well!

Paul, as much as I would like to use a teensy3.1 together with a RPi and a bridge in between them - I have not heard of anybody who feels like porting the bridge to RPi or of anyone who has done it already (http://www.linino.org/forums/topic/porting-the-bridge-linux-side-to-other-linuxes/...

That is unfortunate for the community, that's true. Thanks for the post.

Renaming class File to MyFile to avoid conflicts with the SD library. Hi Paul I just altered your Bridge library version renaming the File class (in FileIO.h/.cpp) to MyFile to avoid conflicts with the File-class of the SD library. It works well and allows me to copy files from the linux to...

I just connected 3 RA8875's with corresponding 5" TFT's (800x480) to a teensy 3.1. When using the MISO tri-state buffers and the pullup resistors on the CS- and RESET-lines, the setup works like a charm. However - the displays draw quite some power, each of them about 250mA @ 5V. Since the...

Paul, you should send that link to adafruit support or post it in adafruit's forum!
