Hi,

I want to create a button-pad and therefor I have got me some of this Velostat.

In first experiments, simply two wires with a slice if velostat as a bridge/switch over it, worked fine.. ...

good point, thank you.

Hi

I need to choose a battery for my Teensy3.6-Waeable-Project.

Here is some criteria that it needs to have:

1) as small as possible
2) long duration and much power
2) need to be...

Hi

I had my first tries on T3.2 and the AudioShield. Everything worked as it should. So I changed the T3.2 with a T3.6 and now only big noise gets out of the AudioShield.
I loaded the...

I am playing around with TeensyAudio and have some questions for which I cannot find anything in the web.

1) can a raw/wav/mem be played from a certain position? (sampleStart)

2) I am...

that did it :) thank you :)

I try to build a simple looper.

There should be 4 samples that a user can trigger via button and the play/stop/rec-buttons for the looper. In rec-mode, the looper should record when the user is...

Hi

I am very new to Teensy-Audio so please be patient with me :)

I want extend the Audio-Example: "Part_2_03_Samples" so the sample-playing is beeing recorded.. a simple looper.

1) when no...

#metoo :D

.. seriously, I would love to see how you did that.

this seems to work perfectly :D

thank you very much.

Hi,

for my project I need to have control over 16x WS2812B (or a other RGB-SMD-LED with same size) seperately.

I have bought some of these to test, but I can't figure it out, how to control...

bro .. works:) ! .. thank you

Hi

I somehow have serious trouble sending vars through serial between my Teensy and Raspi.

(I want to send strings like: "myVar:1;")



int i = 2;
Serial1.write("myVar:");

hi,

i had a first try ever and got my first PCBs delivered .. while equiping it turns out, that i made a mistake in the blueprint for my slide-pots so I had to be creative.. the holes are too...

I did.. (I use T_3.6)



const int ShiftPWM_dataPin = 28;
const int ShiftPWM_clockPin = 27;

but it is not working.

Hi,

something I really don't get.. in the shiftPWM-lib i have to uncomment the following lines to get it working


#define SHIFTPWM_NOSPI
const int ShiftPWM_dataPin = 11;
const int...

Hi Paul,

thanks..


I mean for example this B10K18.. sorry i can't find the datasheet.

hi,

- can someone explain the difference between common potentiometers with 4 pins, and thos with 4 pins?

- I need 38 potentiometers in my project, and I am looking for good (reliable) ones,...

Hi guys .. thank you for the advices.

I have now tested EVERYTHING .. and now I found out that it really was wires.. i have ordered me some more jumperwires and breadboards from amazon and after...

Hi


yes, with a 10K resistor.


Oh, i'm sorry.. forgot to change the pinMode back after I tried various things.. it is both pinMode/digitalRead on pin 14

Edit:

is my Teensy broken? ..oO

I unplug everything and load the pushbutton-example

void setup() {
Serial.begin(38400);
pinMode(7, INPUT);
}

Hey folks,

i apologize in advance for this, .. this is really stupid, but don't know what to do anymore :/

i am working on a bigger project (some of you may know me because i often ask...

that is a great idea!! .. I am now working on a other problem of the project, but I will make this for sure. thanks bro :)

thanks :)

.. it is not the converting, it was the timer-resolution :) with micros() everything works like a charm :)

@Paul
.. yes I know, sorry :/ .. I'll try to follow better. I am really thankfull for the help here. Without this forum I would be able to do nothing :) I try to learn as much as I can, but...

Thanks I tried around a little bit, and now it works. Adapred the last example from the thread:

Hi

I do initialize some classes and a button called "btShift":



#include <Arduino.h>

#include <cfg.h>
cfg cfg;

thank you very much :) .. trim() works perfetly :)

you are right ..oO .. there should be 20 chars in the string, but there are 21 ..

is there a easy way to trim that in c++? .. I am searching my ass off but all I find seems way to complicated.

@Theremingenieur .. nice thanks :) ..

should I have an eye on what tolerances the components i use in a ciruit have? maybe choose components with the same tolerance? .. of course there are not...

Hi

I heard of platformio and thought I should test it out.. I use VisualStudioCode anyway so...
first impression looks very cool, but I have some issues I cannot resolve:

did i understand it correctly?

many components in a circuit do many things, which means they consume current. the more components there are, the more does the current vary .. so one corrects this...

but how come? .. I mean, when I do the schematics .. then when soldering and wirering.. äi thought I have to take care, that everything is stable(?) .. I don't get it why there would be a need to...

Hi,

so now the point has come at which I have to deal with coding a sequencer for my project.

this has nothing to do with the thread-question but as I want the sequencer to be very feature...

oh I just typed it in here.., these are not there in the output.



I have deleted the file and written everything again from scratch, no whitespaces or nothing.. simply:

hi
so the content of startCfg.txt is:


MappingPreset:Default
Pattern:Default

hi

on my SDCard (T_3.6) I have the following structure:

| - startCfg.txt
| configs \ default.txt
| configs \ myConf.txt
| pattern \ default.txt
| pattern \ myPattern.txt

Hi,

I don't understand why it sometimes works and sometimes not, but after formatting the SDCard with the SDFORMATTER the problem is gone :)

Thank you :)

yes I can use it in a raspi without any problems
the teensy is powered via usb

in the examples there is also this line

if (!SD.begin(chipSelect)) {
on which sometimes it fails..

Hi

how can it be, that the SD-Card sometimes works, and sometimes not?
(in this case I have to plug-off the Teensy, and plugin it again,... sometimes it works again and sometimes I have to repeat...

yes I already saw those.. also took a look at those spy-pens, which are nearly exact what I need..but there always some problems.. I would need to hack them, or the resolution is not good enough....

ok, cool thanks for the explanation :)
will correct that.

Hi guys.. I just found out, I took 22Ohm resisors instead 220Ohm. .. I mean, it works.. should that bother me? should I change that?

Hi

thanks so much :)

unfortunately all those cameras have a too low resolution and they are too big :D

what I want to do, is to put the tiniest camera i can find to an end of a stick (a pen...

I would like to take a really small camera, maybe from a smartphone, and output the signal in realtime to a TV.

Is that possible?

What are the smallest cameras available?

yes I got that working with two tennsys now, but raspi just wont read anythig :(

the curious thing about it is, that I got that wokring a while ago.. I wanted to check out if I can use the Raspi...

oh.. thanks.. now that seems to work now.. on the recieving T 3.6 i println the incoming Byte and something comes in.

now back to the Raspi, still nothing coming in -.- .. I know this is the...

yes I did wire it that way:

Teensy 3.2 .................. Teensy 3.6
RX0 ------------------------> TX0
TX0 ------------------------> RX0
GND -----------------------> GND

Hi

I once got had the communication from Teensy to Raspi working, but since a few days I got back to work on it and it just does not work whatever I try..
So I went now to test it between Teensy...
