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 progress). In the same vein, from the photos, I didn't realize that the Ethernet pads on T4.1 weren't...

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 teensys : https://www.pjrc.com/teensy/dimensions.html I will get my caliper out and measure the few...

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 than unsoldering the micro-USB from a Teensy LC and soldering the USB plug to the pads under the LC...

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 this exact version and they MATCH ! \o/ If by any chance it would be usefull to anybody, here is...

Continuity PASS Testing gadget PASS https://youtu.be/XdCpBaHFeb0 \o/

Soldering done. But before firing it up, I'll test everything for continuity and probably make myself a test rig (essentially a fake DIP40 with leds on every pins).

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 time is more valuable than the first Chinese programmer I can find :)

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 expensive for my 4 chips need), but after some searching everybody seems to use some multiplexers and less...

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 : Ben Krasnow explains how he captured images from his analog electronic microscope using a Teensy LC to convert and send the data over USB.

The link to your inbox will not work for us ;) http://www.visualmicro.com/

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 and VCC is sturdy enough. I can pull on the board or connector with confidence, but won't tilt it...

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 ! On a tottaly different subject, in the Adafruit_SSD1306.h line 142 should be void dim(boolean dim); and not void dim(uint8_t contrast); It only poped as...

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.

[Solved] T3 hangs with SD & interrupts Hello, I have a fairly complex (for me) project : make a fully automated astronomy photo mount. This means : - A teensy (3.0, may be upgraded to a 3.1 if needed - I already have them) - A Sparkfun LSM9DS0 IMU Breakout - 9DoF wired in I2C mode (official...

Just if it is of any use to anybody, I made a small program to set the Teensy 3 time, according to http://www.pjrc.com/teensy/td_libs_Time.html#teensy3 Win 32 Binary Delphi 7 source code

Redone all my wiring, now it seems to work reliably. The CC3000 software still needs some work but it does the job.

Hello, I'm in the process of creating a (very) small (30*8) led display that should be able to be driven remotely, but I'm facing instabilities using Adafruit's CC3000 breakout board. I don't know if it's my wiring (likely but checked many times), the CC3000 power draw (it never exceeded my 5V...

If, like me, you don't have any Idea what pacific time translates to for you, an easy way to know is http://www.timeanddate.com/worldclock/converter.html?year=2013&month=11&day=29&hour=9&min=0&sec=0&p1=137&p2=0 Just select your place and click convert time.

Hello, I'm in a project that uses all (yes, even the E4 & E5) the teensy 2 ++ pins, so I needed a reference table to remember all the pins while soldering. It's based on the Pins PDF + the Wire & SPI application notes. as it's a Excel file (I use OpenOffice) you can modify and sort it as you...

Yes, and yes.

I don't know if it wasn't fixed in a recent update, but the sketch I'm working on does exactly that (define the pin again every time I need to switch modes) to address this issue (which may or may not be corrected since). I never changed PWM frequency, but I know it can be done in the latest...

1) desolder the adapter 2) bridge the 3V jumper with a blob of solder 3) solder wires according to their usage : +5V goes to 3.3V Ground goes to GND MOSI goes to DOUT (pin 11) MISO Igoes to DIN (pin 12) SCLK goes to SCK (pin 13) SS goes to CS0 (pin 10) the teensy3 led should flash when you...

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 project I was thinking about yourself.

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 the other end and served me well for many month now. I use isolated resistor networks (on ebay) to...

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 cells are overwritten a lot (I use EEPROM.write) while I write and test my code (the final project...

THT, this picture is the old, wrong one (I know it's on the KS front page, but Paul explained that he can't change anything there after the ks was finished. this is the one you get with your teensy :

The problem is that the internal sensor is ... internal, and will be subject to fluctuation depending on the core use. I bought a pack of 30 no-name crystals for 3$ and they work fine. The thing is I don't need super-duper precision for the projects I'm working on. I'm getting less than 1s per...

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 devices, but CSx is specifit to each device. The light gray SPI pins are, as JBeale just said, just an...

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 most elegant is ask "PaintYourDragon" if he could do the mods (which should be trivial for him) in...

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.
