    thank you for your answer.
    I think the euroshield is somehow a too limiting approach, since the number of outputs/inputs as well as the module layout, i.e. the knobs etc. is predefined.

    is this still under consideration?

    I think (especially with teensy 4.0) there is a lot of potential in building eurorack modules from teensies, as long as the audio/CV in/out is available as a...

    thanks for your answers!

    In my understanding of i2c (correct me if I am wrong), the arduino should stretch the i2c clock until its "receiveEvent" handler has finished. So in theory the teensy...

    I use the adafruit library, which I have modified quite a bit (the important difference is that the display buffer is now a member variable of each display object).
    If this has enough features for...

    storing an 128x64 display buffer takes about 1 kB of RAM. The teensy 3.6 has 256 kB, so you could have a buffer for each display without any problems. That way you only have to redraw the display you...
  6. i2c communication (400 kHz) between teensy and arduino - delay required

    Hi,

    I have a teensy 3.2 connected to an arduino mega via i2c, pullups 3.9 k to 5 V. The teensy is the master, the arduino the slave.

    The communication is working fine with the standard i2c...
  7. Many SSD1306 OLEDs plus encoders and RGB LEDs

    Hi,

    this will be a long post with a lot of questions, if it would be better to split in separate ones, please let me know.

    I want to create little modules with an SSD1306 OLED and an RGB...

    wow! Thanks a lot!

    Now I have to get a teensy 3.6 :-)

    I guess the bigger problem is to find a good and cheap usb hub with many ports

    does this mean I could connect a usb hub to a teensy 3.6 and connect as many other teensy boards, lets say LCs to the usb hub and have all communicate via their own serial object instance? Does the...

    Thanks! I'm searching...

    One thing is a bit strange though, why is the default modulation config working with the avrs and not the teensy? Does this make sense?


    That would be nice!

    Both devices use the same modulation mode for sure (I'm still using the unmodified example sketch, except for the modem setting, which is the same on both).

    ITS WORKING!!!!!!!!!!

    Searching the radiohead user forum reveals that i should use another modem config. So I changed it to GFSK_Rb55555Fd50 and now everything is working.

    oh sorry, I completely missunderstood you. Of course, this is dump to have it like that.

    I run the client on an AVR (atmega 328) and the server on the teensy. The unmodified code shows this...

    Of course, this was the code i started with.

    when i remove this delay, the teensy is not able to send any package anymore, especially no ACKs. And...

    Hello,

    I found the time to try with a new Arduino and a new RF69 Module. Using the same RF69 Module on Arduino works out of the box with the examples from the radiohead library, but when I...
