    I2C error 4 for Wire.endTransmission(true)

    This is my complete code wich runs on the arduino uno. #include <Wire.h> #include <SoftwareSerial.h> const int SUNRISE_EN = 8; //serial EN pin const uint8_t SUNRISE_ADDR = 0x68; // communication address const int ATTEMPTS = 5; // Amount of...

    I2C error 4 for Wire.endTransmission(true)

    I tried another teensy 3.2 too to be shure it's not the controller. Same result there.

    I2C error 4 for Wire.endTransmission(true)

    I have a "Senseair Sunrise" CO2 sensor and i got a reference code for that. It works perfect an an arduino UNO with the following connections I soldered the two connections on the sensor itself directly there. So just 5 wires go to the controller. Then i connected the same sensor to a teensy...

    Teensy 3.6 & RFM69HCW

    The Whisper Node Code works without changes on the Teensy 6.6 too. The Values from Whisper Node are beeing received too. ============================= Bat: 2427 mV Pow: 5118 mV Tmp: 2696 °C Hum: 3983 %rH ============================= Bat: 2427 mV Pow: 5110 mV Tmp: 2694 °C Hum: 3978 %rH...

    Teensy 3.6 & RFM69HCW

    Oh i missed that IRQ PIN. I was not aware about that one somehow. :confused: The full connection now is: RFM69HW GND*2, NC >> all to GND RFM69HW 3v3 >> Teensy 3.3V Out RFM69HW MISO >> Teensy pin 12 (same pin within Whisper Node AVR) RFM69HW MOSI >> Teensy pin 11 (same pin within Whisper Node...

    Teensy 3.6 & RFM69HCW

    I see your point, but i wanted to check first if somebody has a solution already. Here are the infos. I used the Talk2 Library and the Radiohead library to connect two Whisper Node-AVR: https://bitbucket.org/talk2/talk2-library/src/master/ I used the example sketches "Voltage.base" and...

    Teensy 3.6 & RFM69HCW

    Hello I managed a working connection between two "Whisper Node - AVR" (with RFM69HCW 868Mhz) easily with the help of the take2 library examples. But i want to have a teensy 3.6 on the server side and a whisper node on the client side (a sending low power measuring node with deep sleep...

    Runtime errors maybe

    I wrote a quite complex code for a clock application. I have the very sporadic situation the teensy 3.2 stops working in a random situation. After disconnecting and reconnectiong the teensy from the 5VDC source, it works again. I don't know the cause for that behaviour and it seems not so easy...

    Compile issues on Windows Arduino IDE 1.8.1 (Windows 10), TD: 1.35

    I found the nasty trap. The CPU speed was set to "8MHz (non USB)" from a previous project. It needs to be set to 24MHz or higher, to include USB functionality of course. No reinstallation was needed. I found it while comparing to a second new setup in a VMware-Image. It compiled immediately...

    Compile issues on Windows Arduino IDE 1.8.1 (Windows 10), TD: 1.35

    Thanks Im not shure about the answer, but i wrote that i chose "Keyboard" from the USB-Type menu. Are we talking about the same? Regards.

    Compile issues on Windows Arduino IDE 1.8.1 (Windows 10), TD: 1.35

    I can't get the examples compiled. For the example "Buttons" from menu File\Examples\Teensy\USB_Keyboard i get the error C:\Program Files (x86)\Arduino\hardware\teensy\avr\cores\teensy3/Print.h:86: undefined reference to `Keyboard' collect2.exe: error: ld returned 1 exit status Error compiling...

    Atmel Studio & Visual Micro / Compile error

    Have you looked here? http://www.visualmicro.com/forums/YaBB.pl?board=ArduinoVisualStudio10 ;) Why do you post timeconsuming needless rubish concerning other IDE-implementation when you say you don't support that. Then better don't post at all. That'd be more helpful.

    Atmel Studio & Visual Micro / Compile error

    Well i looked at it. Very unclear description what to do. "teensy31.build.flags.ldspecs=" or "teensy31.build.flags.defs=", comment this uncomment that, twiddle this and twiddle that, not clear where to post in the text file, not clear how to seperate from other enties. That post is simply a...

    Atmel Studio & Visual Micro / Compile error

    Is there really nobody with any solution? I tried the teensyduino 1.22 meanwhile with the same error. A colleague recommended me the teensy instead of the regular arduino boards. But i'm not shure if that was a good idea because it compiles only in this arduino crap editor. :(

    Atmel Studio & Visual Micro / Compile error

    I installed Arduino 1.0.6, Teensyduino 1.2.1, Atmelstudio 6.2 and the current Visual Micro to work with a Teensy 3.1. Those should fit together according what i have read on the Visual Micro Site. Newer Arduino and newer Teensyduino is not tested or recommended at present to be run in Atmel...
