    AndyA replied to the thread MTP file dates.
    I suspect our issue could be resolved by calling the loop function more frequently and so preventing the receive buffers from filling up as much. But the system is doing a lot of other things at the same time so that's not the easiest thing to...

    Not really a matter of skill. Its from experience working with the I2CDev lib. The lib actually supports a few different methods for I2C, one was standard wire, another was a fast wire type and a couple of others from what I remember. Its been...

    Minor background comments: CS Pins: Most libraries do not do anything special with the CS pin. That is they typically use something like digitalWrite to set and clear the state. However, there are some libraries, like some of our display...

    Yes, it would be nice to convert all of that code that is setup for each of the displays into a table each. It might make it a lot easier to detect things like what is different between ILI9488 and ILI9486... At some point maybe someone will do...

    To access a teensy file from a program, you need some SW that lets you mount the file. I use windows and there is no easy way to get the device letter assigned to Teensy disk without another interface layer. Also one needs very likely partial...

    Thanks for reply jmarsh, I have one question in the attached program I have configured channel one to produce pulse of width 32 1588 clock mode. I am observing this on pin no 24 of teensy. I am not getting the pulse can you please help in this.

    You must use at least 1 rev D board (for channels 3-4). The other can be rev D or rev D2 (for channels 1-2). Instructions for Teensy 4.0 and Teensy 4.1 are virtually identical. The rev D audio shield which becomes channels 3-4 needs to be...

    Very nice @WMXZ. My program compiles now without any warnings and SD.h (@h4yn0nnym0u5e code) is unaffected. All tip-top :) Bless you. I wonder if you guys ever play or open files directly from the Teensy/SD card via MTP, or rather always copy...

    As you can see, I've designed a new Teensy that is more user-friendly.The project is based on Teensy 3.2 . I added a step-down module that supports up to 17V input and 3.3V@3A output.Two pads were added for EEPROM and FLASH.The new Type-C port is...

    The comments in the example file tell you how to switch to other SD cards.

    Thanks for your message. I know that, but this one uses the sd card reader on the audio board. I would like to use the sd card reader on the Teensy 4.1 and not the sd card reader on the audio board.

    Odd for it to be LOCK'able related. Would be the first report of something acting differently AFAIK?

    royontog replied to the thread SPI pins of each ports.
    I appreciate the reply. That made me look at it a little harder. The answer (for me) is to use SPI1 with the alternate MISO1 and CS1 pins. That leaves TX1/RX1 available. Thanks, Kurt!

    I've used analogue multiplexor chips (4051 8 input / 4067 16 input) to read multiple touch pads from one pin. It costs you the addressing pins and an enable pin but you can share those pins among a few multiplexor chips and read many capacitative...

    @fan_2021: Take a look at <this> post. Note that you will need at least one original Rev D audio shield to go along with your Rev D2 in order to do quad audio. Hope that helps . . . Mark J Culross KD5RXT

    @joepasquariello , Thanks for the reply. But that thread doesn't mention anything about teensy 4.1 audio shield rev D2 mod.
  • J
    Do you mean you want more analog inputs? There are many A/D converters out there with I2C and SPI interfaces. You might start with the Adafruit website.

    Hi, I just bought Rev D2 audio shield for Teensy 4.1 Can someone point me to the instruction for modifying rev d2 for teensy 4.1 to do Quad i2s audio? Most resources online show rev D. Thanks!

    Spot on! I have the touch working now as well thanks to your lib, seems to be working exceedingly well to me. I'll keep an eye out for the new branch as well.

    I thought I did :unsure: After a few distractions I am back working on it. I would like it to fall more inline with the way the FT5206 is used in the RA8876LiteTeensy library. I'll start another branch on GitHub for that...

    You're right. Probably it's the best way. Which Teensy card is compatible with the REV D audio card ?

    Yes, simply buy a Teensy board.

    Is it possible to have just the code for configuring the LINE input to the I2S_OUT output ? So that I can visualize ?

    No, it will not work. That library is for Teensy.
