      Thats a nice looking enclosure. I don't think there is an audio design tool to do speed or reverse playback. I think you could read the wav file and manipulate the data however you need to to and use the queue tool from the audio design system...

      Is it possible in ANY way for successfully compiled code to cause a failed upload like you are saying? I don't think so. Is it possible running code could cause an electronic issue say pulling a supply low and cause uploads to fail? I think so...

      Correct. And the Program button on the Teensy is wired to the Program pad. Either one of them is fine to put the Teensy into waiting-for-new-code mode. Paul

      Occasionally when i go to upload a program it doesn't work. This happens in windows and linux and I have my theories as to why but... regardless I press the button and without having todo anything else the code is uploaded. That same...

      Ok. So I think I will put a pushbutton from this “program” line to ground through a 1k resistor sound good? Then if things go wrong I can walk over and give it a push.
    • G
      The pushbutton is wired to connect the reset line to GND.

      Correction, a power cycle did fix it just now.. I think i have a diode/cap setup that needed a longer discharge.

      Thanks Bri. I overlooked this. (didn't look at all :( ). so does the active-low reset pin do the same as the program pushbutton? I know power cycling doesn't allow me to re-program.

      I have a teensy 3.6 in an LED cube that is a bit of a hassle to get at. I have a raspberry pi zero connected locally that I use to upload new code to the cube. Sometimes I get the following error when uploading using teensy_loader_cli version...

      Again, just another guess without being able to look at your complete code: what is after the code snippet that is shown ?? The second instance of Serial.println(retrySBDIX); is terminated with a semicolon, but there is also an opening brace...

      It could be the battery voltage going too low under load, it could be the current limit on your buck converter. Invest in a variable current limited power supply and do some more testing is my advice. Gaivn.

      It’s probably been 10 years but I should ask for my money back

      For example I just copied your post #27 into chatgpt. No changes. The answer it fired back is correct and pretty clear.. if it wasn't you could ask "hey i don't get that bit explain in more detail" and it would. Just be aware it can lie sometimes...

      I find chat gpt quite good for this sort of stuff. When it does give me something that doesn't work right i just tell it and it fixes the issue. If you haven't used it for this sort of stuff it is quite amazing.

      I have a feeling allot of the blanks in my knowledge could be filled in efficiently with a few face to face conversations but forums don’t really do it.

      But when your program is big I think it makes sense to seperate headers and definitions because it makes it easier for me to look at what function prototype is without searching through heaps of code for it.
    • G
      You know the ide may not care what the file extension is. Although I think if you include a “somename.h” and fill it full of function and class headers (is that the right word) and then. Use one of those functions or classes I’m thinking the...

      See how briComp did it. #include <AccessPublicVariables.h> Because he made a file with that file name. As far as I understand it just cooies that file and puts everything in where you place the #include line.
    • G
      am I right in saying you started with one 4000 line “.ino” file and want to make your code more readable. You could just separate the file however it makes sense and put them in seperate files and just “#include” those.

      The Nextion is a learning curve, but works very well if you implement it correctly. Shame they are so expensive (still). I design all my pages in Photoshop in both 'states', and then you can achieve some pretty sweet looking (and working)...

      Teensy Nextion Library Linked above is a library that I have developed for the Nextion Displays. In realty it is NOT limited to only Teensy but anything using the Arduino IDE.

      Hi Steve. Several things about your post have me interested and would love to see those 4000 or so lines of code. Interesting bits: For eight years I've updating hardware and software on some christmas lights (about 3000 ws2811 leds) which has...

      Hello Everyone, Hope you all having an amazing day. Just joined this forum and wanted to say Hi to you all and get connected with you all. However I didn't find where to post first so posting here :)

      If you can do it on a keyboard or joystick I’m going to guess yes.

      Gibbedy replied to the thread Voltage level of gpio input.
      Do these work by driving each row gpio output low sequentially and checking all the column inputs to see if any of them are pulled low?. If so what voltage are the column inputs pulled up to? What value of pull up resister are you putting on...

      Hi jack. I would suggest reposting your question with the smallest complete code that can be compiled and give the fault you describe. I would also suggest providing a link to the library that you are using. Sincerely Gavin.

      Hello Luis. I’m currently using 11 outputs on a board I made for 14 outputs.. I’m not sure if I chose that number because of a hardware limit but I’m pretty sure 14 will work. I only use 300 leds per strip however for what it’s worth I just...
