Thank you for those infos, but for example, T4.1 has passives underneath (unlike the Teensys I got so far), and I had to take this into account when modelling my project box (a work still in...

Hello,
I'm in the process of creating a 3D printed case for a project and wondered if a web page reported the boards physical sizes.
There is one but it seems it's not up to date with post-3.6...

You may have damaged your LC in another way. The only needed pins for normal usage are 5V, D-, D+, GND.
Those pins are in the right order to solder a male USB connector to the LC.
I can confirm...

I've been able to perfectly read an W29C020C-90B EEPROM chip from an Abit KA7-100 Motherboard made in the year 2000 (I kept the EEPROM "just in case") and I was able to download the BIOS file from...

But before firing it up, I'll test everything for continuity and probably make myself a test rig (essentially a...

I changed the eprom type for a 29F020, a bit bigger and easier to program. appart from the rat's nest of wire, the hardware part should be straightforward.

Thank you, I only could find some distantly related projects and the datasheet of the eeprom.
I'll try to do it and document it as well as I can.
I'll stop trying when it works or I feel that my...

Hello,

I need to flash some Atmel 29C256 Parallel EEPROM, And thought that a Teensy ++ 2.0 I have laying around would be perfect for the job (and that the commercial programmer are way to...

It doesn't. You'd have to unsolder the usb mini and replace it with a USB A plug (which is easier than with the micro plug on the teensy 3).

No rush for me (my project is not urgent in any way), nice to see it's a WIP. Thank you Paul for all your work.

Any news on this topic ? This mode could really benefit from the bigger storage available on the Teensy 3.*

Hi everybody,

just to mention an excellent video on the Applied science Youtube channel :

Not yet. But I plan on flooding the then-to-be USB Key with hot glue. I think epoxy would be a good candidate but I have none handy. Cyanoacrylate seems too brittle to me.
For prototyping, the GND...

Thank you, I was able to convert one of my Teensy's to an USB stick (ripped the reset button also, for flatness) :

Neat !

Would you consider selling a few on Tindie or elsewhere ?

Playing with some ESP8622 I had more opportunities to use and abuse the new console, and I can say that it's better in every way. Thank you !

It seems the Mouse.move(x,y) has reversed directions. To achieve the same directions as 1.20 I had to replace it with Mouse.move(-x,-y).

Not a big concern for me, but you never know...

Thank you so much for your work !

Thank you, it works flawlessly now.

Noobish question :

I downloaded the git zip, extracted in my libraries folder, loaded the Mp3FilePlayer example and got those errors while compiling :

Great !

For those of us that don't live in the negative longitudes, this website may be of help : http://www.timeanddate.com/worldclock/meeting.html

That solved it ! thank you so much !

Thank you for the advice, I removed them, but the board still stops working after the fuirst use of the interrupt.

AFAIK the pins used for SPI are on the other side of the board. This daughterboard was created to be mounted like that on a Teensy2, not a Teensy3.

It has been done before with a teensy 2, but the SPI bus is slow and the transfer speed where very slow. Maybe the teensy 3 can do it faster, but it may be a lot of work.

** EDIT ** you found the...

There are smaller flavors of Arduinos. The next thing to be aware of is the voltage needed by the device you are interfacing with. 5V ? 3.3V ?
5V => Teensy 2, 2++
3.3V => Teensy 3

does the DC-DC convertor still work ? (do you get 3.3V on the pin after pin 23 when powered from USB, when powered from vin)

you can go for 330 Ohm for extra safety (I measured mine again with 220 on a Teensy3 and it was a bit over the recommended 9mA rating). I use it with an arduino Mini Pro to drive a DSLR shutter on...

You have to use an additional chip for that. Like a DS1307 or a DS3234. The DS1307 needs an additional crystal, and both need a power source to keep time when the teensy is not powered.

Your talk about Flash wear worries me a bit. Currently the EEPROM equivalent is wiped out at each code upload, which forces me to load it back each time, writing it another time. This means those...

With no resistors at all, either your opto-isolator or your teensy output will fry. Maybe not immediately, but be prepared.

I use some CNY74's with 220Ohm resistors, it draws less then 6mA

There is only one SPI port available, with 5 Select Lines ( CS0 to CS4 ) so you can directly drive 5 SPI devices with 1 port (CLK/DIN/DOUT/CSx). That means that CLK DIN & DOUT are shared by all...

Am I really the only one having a T2 and W7 here ?
Maybe making this thread sticky maybe would draw more attention. Don't let Paul down when he ask for help !

What is involved, really I don't know, no time to read the lib myself.

To make it work you preferably have to posses a Teensy 3 AND the display, which I don't.

The solution I would find the...

Yes, it seems that you need to modify the library to support the T3, or wait for somebody else to do it. I don't have such a display so I can't help you further on that one, sorry.
