    I converted the images to C and loaded it into Progmem Then I used the Adafruit GFX.h library's bitmap routine and that seems to work well. I used: const uint16_t Border PROGMEM = { 0x0000, 0x0000, 0x0000,...

    Thanks. I will look at that. This is supposed to convert images to C source code..... but of course, it doesn't work https://github.com/bitbank2/image_to_c

    These examples are great (such as the https://github.com/bitbank2/JPEGDEC), but they don't appear to show you how to get the images into the flash memory to start with. There always seems to be some critical piece of...

    Wow. I have to say at this point I am baffled. Just adding a PSRAM chip to the smaller pads, as I think that will be enough. But I have literally found about 6 different ways of implementing LittleFS and I just...

    We always put the audio board on the Teensy. However in this instance, we didn't have the headroom. Pretty sure that isn't the issue, as we have the problem on several other projects where they are stacked. I am...

    No it's not the SD library. Well, maybe it is in this case, but the screeching noise has been a constant on several much simpler projects. At first, we thought it was a power supply issue, but we ruled that out. ...

    It is a shame. I do like these modules, but we used them for several large installations on some commercial projects and had nothing but issues with them (those were all 3.2's + audio boards). I am not the main...

    OK. Decided these Teensy Audio boards suck. Having so many problems with them that I just can't rely on them. This weird screeching issue is affecting a ew of our projects. Seems to be some issue with the comms to...

    Hmm. Not sure how to fix this. I always put a line in to make sure the sound file has finished playing (+ a slight delay), before it tries to retrieve an image from the SD card (where the sound files are also...

    Hi all I'll dig out the code tonight, but I am having consistant issues on many projects with 3.2's and their associated Teensy sound boards and 4.1's and their sound boards. They randomly emit a horrific screeching...

    Could I simply put a single sacrificial RGB led in the actual controller box as the first led? Am I wrong in thinking that first WS2815 RGB strip individual driver chip will then output a 5v level signal onwards?

    Hello all I have a Teensy 3.6 outputting Fastled data. Reasonably simple project. 12v RGB strip by the way. I need to extend the cable to the leds, and at 3m I am starting to get data issues. I believe it is...

    Putting this in fixes the issue.. dmxTx.setPacketSize(100); dmxTx.setRefreshRate(40); What the heck in means, who knows. I just don't understand why they bother to give you a text list of Keywords, and no...

    Hmm I am starting to think this is something to do with the entire TeensyDMX library. We used DMXsimple on another project and it worked fine. But DMXsimple doesn't compile on a 4.1, it throws up an error

    Hi all I am using TeensyDMX.h on a 4.1, with a CTC-DRA-01-R2 DMX shield. Daisy chain of 8x DMX lights on the system, and they all work fine... except two lights of a particular type. These two don't play ball...

    Hi I know Teensy's don't support OTA programming, but do you think it would be possible to remotely implement? We have multiple controllers running 3.2's and the customer now wants OTA capability. That means...

    We have abandoned Teensy's unfortunately and gone over to ESP32's with WAV boards. A lot of our prototypes were based on 3.2's and they are just not available and we can't wait any longer. Also, we kept having...
