    glad you got the BMP showing with the 'real' code. not sure where your original code came from, but whatever the case, you need to break it down into smaller parts and check the flow, otherwise its just garbage and you...

    your code in post #1 never calls the leds to show their colour status, even if the colour status is updated from the buffer. also, in that code (which isn't mine), there are a bunch of other issues related to image size...

    Hi, we all have to learn, and hopefully are still doing so. Exactly which test (rainbow / fire / etc) worked with your leds? under the teensyduino file menu > examples (Fastled or octows2811 or other)? from the above, I...

    Hi, I don't recognise chunks of the code you posted. Do you get the serial monitor print statements from the drawbmp functions. Also, I can't see anywhere where the programme sets the leds, whether its leds.show() or...

    Hi, I think that KurtE was actually saying that the signal and the power need to be of the same (or similar) voltage. Even though you are using 5v separate power supply, the teensy is still only outputting 3.3v data...

    a classic use of sample and hold in modular synth is to sample a noise signal to obtain a random voltage value and use this to set something like the resonance or cutoff value of a filter. If you set the rate of...

    Glad it's working. Also, just a reminder, that zerois counted as the first file in your loop, so 20 files would count 0 to 19 as your loops are written starting from zero. You can also write code that counts the...

    possibly five tracks has been hard coded into the code? you have several places where button count is reset to zero or four if it crosses those thresholds in the incremental loops. I suggest changing the hard code "4"...

    ah yes, check all if() statements, as = must be == when doing a compare. they are there throughout the control change routine

    glad you got it working. state machines are building blocks of many projects, so its good to understand them. Had a quick scan and it look good, the difference comes from there being two leds per colour, and my...

    Stick with the state machine approach for now, its worthwhile. below is the kind of thing you need to do, but i am a bit rushed at the moment, so its the concept rather than the specifics below Firstly, you need to...

    HI, this "For example if I tweak a CC the LED strip will turn on to that value, regardless of the fact that there has not been a noteOn message." relates to my suggestion in the pseudo code with the line //add lines to...

    This: "This is working OK in the sense that MIDI CC#18 will now effect the brightness level of the LED when it turns on, but once it's lit the brightness level is fixed at that value and CC#18 has no more effect on the...
