Great. IS62WVS5128GBLL arrived here and soldered on teensy audio

Now I'm trying to update effect_delay_ext.cpp, it is the only effect which uses external RAM.
I'm reading the datasheet and from...

outstanding. everything working now

Thanks @tonton81.
I've updated with some pullups and data is transmitting but interrupt pin stopped working. should I do something in that pin too?
I've changed IC VCC to 3.3v now so I use pullups...

I'm trying to use the PCF8574P port expander with Teensy 3.2 but I can't receive the transmission yet.
I'm posting the wiring and the code.
interrupt seems to be working, but no transmission yet. ...

I hear this is the same chip, only Newstar brand use NS as a prefix

I've been testing the new chip HD107S which seems to address most of the issues descibed in APA102 in this compreensive Paul's analysis

Thanks for the detailed explanation @Blackaddr
I'll be ordering some of the IS62WVS5128GBLL-45NLI and I'll report here after installed

I'm wondering if they newer SRAM chips are compatible with Teensy Audio

Thanks for the answer and sorry about the duplicate

quick question:
Is Audio Adapter compatible with Teensy 4.0?
Thanks

Quick idea: Try to take a look on browser identifiers
navigator.appName, navigator.appVersion, navigator.platform
sometimes in the past most of the spam come from the same engine, returning a very...

Thank you @BJB.
About full encapsulation you mean a sealed box or equipment wrapped in something?
Maybe a good thing it doesn't have temperature variation, it will be always 10°C

Thanks. In this case I'll prefer to coat everything.the thermo rectratable option have this problem of holding humidity inside.
I'll try to spray with everything plugged so there are no holes...

Hello, I'm developing an installation meant to be in a high humidity environment (91%) and I want some advices of how to protect the electronic equipment on it.
It is meant to run during one year.

Sometimes I've buy 10 or 20 Teensy 3.2 or 3.6 directly from PJRC store.
It would be great to have a version without headers and pinout sheet, Teensy only. Maybe grouped as 10 items in the same...

I use my computer as a server to distribute the firmware (fixed ip, something like 192.168.0.10/firmware.bin )
esps are ready to receive an udp command and that starts the update process (check...

Hello, I've been using OTA on ESP8266 to update about 50 devices at the same time.
Is there some similar library out there to update Teensy firmware via Ethernet?
Thank you

Are you using a Midi In and Out cable in the same device?

Just wondering about some methods to track a video camera position / orientation in a live show, outputing something near enough "absolute" coordinates during some time.
I know some sensors tends to...

Hello, I'm just wondering here if there is a planned life cycle for Teensy 3.2.
It is my favorite Teensy, talking about form / function, handling etc.
Love the 3.6 too but for most projects I don't...

A quick question: with this library I can handle more "universes" like having 4 DMX Outputs in one Teensy board?
Thank you @shawn

Sorry I've just noticed it is another form factor: it is WSON-8 instead of SOP-8.
Do you think it fits in Teensy Audio Shield PCB? I've noticed the alongated rails :)

Winbond recently put an...

Yeah! I've bought the last one :)

Outstanding project, I want to order one to Brazil, I can pay you directly via Paypal @Blackaddr
Tindie site doesn't have shipping to Brazil.
Thank you!

Would you mind sharing the updated sketch here @StefanPetrick? Thank you!

I dislike the Arduino IDE and use sublimetext, and a typical setup for me is:


#include "DmtrPixelnode.h"

void setup() {
setupPixelnode();
}

void loop() {

I've just built a nice dmx controller for a party, with bpm tap, lots of scenes and color palettes, nice and smooth fadein and fadeouts (customizable with knobs)
for convenience I've made an Arduino...

Thanks @chipaudette. Yes it would be great to try out this board, but one thing I like a lot on Teensy Audio Board is I can extend it with RAM or SerialFlash (which I'm using a lot lately).
I know...

Hey @chipaudette, I've just signed up there. do you think it will be a nice platform to develop realtime instrument effects?
Thanks

Hello, I'm here asking for security advices.
I was thinking of using a Teensy + ethernet to make a security layer, permit a specific kind of interactivity using internet to get to the computer, but...

Quick question : to make two identical midi Out ports can I just use the same teensy port and split it to the second?
I suppose yes. thanks

Hello, I'm trying to calibrate sensors on Prop Shield but "Send Cal" and "Send Calibration" are greyed out.
Do I have to collect more data to be able to send calibration or there is something...

I'm using Sharp PC-900V and working flawless.
From what I've seen from the Midi documentation both are acceptable
"opto-isolator (a light emitting diode and a photo sensor which share a single,...

I've tested both Midi spec for 3.3v (10 and 33 ohm) and Paul's recommendation and both work well in my devices.
I've struggled a lot until discovering my volca beats receive Midi In well only if...

Midi in is actually working! Please let me know if I mounted it right, the diode position, etc.
Thank you

Just to let you know it is working great here.
I'm actually erasing SerialFlash files (writing 0xFF) in a different thread.
Thanks!

Yeah the upside-down plus front vs. rear panels can make the pins goes in the same side but it is a lot of confusion.
Other than that I think the center pin (2) is ground, so it only makes sense if...

I mean, upside down doesn't explain because pin 5 is always on left side

I mean, not reversed, but in the photo it says pin 2 is "shield", and schematic is "ground" and I find it being a little confusing. thanks

I've seen this reference and it seems a little bit confusing what to do with pin 5, it seems to be reversed on the photography and schematic. Or I need to understand better what is happening...

Thanks a lot! Didn't know and I was looking at the wrong place. :)

It would be great to have a way of actually erasing files on SerialFlash without calling eraseAll. Would it be possible?
Wondering if one can find all blocks allocated for a specific file and erase...

Hello, I'm looking for some advices regarding APA102 LED Strip.

I've used a lot FastLED library but it now lacks support to Teensy 3.5 and I've researched some options.
One of them is this one...

Sorry I think I've hijacked my own thread.
I choose the path of the Flash chip, faster than SD card but still takes a lot of time to erase everything.
I'm using right now the W25Q128FV with...

Beautiful! Let me know if you will sell any prototypes. I'm interested.

Other question, is it possible to use a NAND chip instead of a NOR chip?
Thanks

Hello, I'm building a proof of concept for a big led installation (about 37000 pixels)
and I'll be using lots of teensies to handle it, I think between 12 and 20, each one with its ethernet...

Thanks! in fact in my application I dont' mind losing packets, I'll use a tiny TTL setting because I'm pushing pixels to LEDs.
I'll soon try this version of Ethernet library just to see if it works...

Thanks for the prompt answer @manitou. I'll definetly take a look in this option.

Hello, I'm working on a project and everything is running smoothly.
I've made an array of EthernetUDP and noticed the project always freeze when a certain number of EthernetUDP objects are created....
