Just to have a good closure on this.

I have been in contact with TinyTronics and at first they did admit that yes they had have cards but they were all gone.
The also told me that Paul...

Hi Paul Stoffregen,

Thank you very much for the offer, much appreciated!

Although it would be nice to have original cards, I do not want to put extra costs on you. I can manage with the print I...

LOL,

Bob Pease, that's a name I haven't heard for a long time.

Always enjoyed his stories in ElectronicDesign.

Hello Paul,

I can confirm it is working for mee too!

Thanks, Otto

hello,

Funny thing, I'm also living in Belgium and have been banned. i can not go to the forum using my GSM on telenet mobile, I AM able to get to this site from my main computer also on telenet....

Hello,

I'm actually living in Belgium and there the was a story about the fact that over here in Europe every country seems to do what they think best and that there is not any real consensus how...

Hi Gill,

hmm, you are using software serial?

why not use the hardware serial ports on the T3.2 I did and it works very well.

like this:

Hello Shadrach,

It is not easy to answer your question because you give very little about your power setup.

What kind of 12 V Lithium battery are you using determines how long you can run, is...

LOL,

the faster the chip.....The quicker it can die?

Yes mistakes are generally not cheap, either in money or in time. Been there and done that for sure and as Frank B said... I will probably...

Hello,

Hmm, what speed are you running? Oleds can be very tricky @high speed and the Teensy3.5 is a lot faster than a MEGA.

Regards, Otto

Hello,

hmmm, I just started again with this display (1.54" 200x200 dots)
Have been playing with the demo code from the library on Teensy 3.6 together with Ultimate GPS and Lipo batt etc.
Yes,...

@MolsonB

Hmm could you specify which Teensy you use?
Some can only handle 3.3V, others are 5V compatible.
About the 3.3V =/-0.3V you are going 9% over the maximum voltage. I would suggest not...

Hello,

here my setup, it's a small GPS system for the car/bike. This is version 2, version one had a ssd1306 128x64 SPI Oled.
This time I wanted a bit more real estate and went for this screen....

Hello Magma,

I'm also using one of these waveshare Oled's on a Teensy 3.6.
I also use the Lib from Sumotoy.
What I found is that I have to select max 96MHz for Clockspeed of the T3.6 to keep it...

Hello,

Looking at your code I see some strange "spaces" in the lines where you set the Conversion speed & Sampling speed.
Is this also in your actual code? Do you get compiler warnings/errors?
...

Hello Paul,

thanks for your code. I can confirm this code also works unchanged on a Teensy 3.6 running @240MHz.
I also have the 1.54" e-ink screen from Waveshare and later this week I will try to...

Hello,

what about one size smaller, a 26500 lion would that fit the bill,

regards, Otto

Hello All,

Why not circumvent the SD card altogether and boot/run from USB SSD? this is possible on Rpi3.

regards, Otto

Small, simple and working! i use it on several 3.2's and lc's

regards, Otto

OK.

looks strange indeed, maybe NOT an original ATMEL part but second source or even worse a dud.

Any luck getting something to work with it? if not able to get anything to work I would suspect...

Hi,

google for "ATRF212B-ZU pdf" and he presto.

regards, Otto

Hi,

look at it this way, with a lipo @4.2V connected to the 3.3V of your Teensy means that you apply an ~27% higher voltage than you should apply.
Even when the lipo is at 3.7V the voltage is...

Hi,

One thing what i did in a gps project with teensy 3.1 was going down in cpu frequncy.
My runtime on a single lion 18650 cell more than doubled. Maybe an option?

Regards, Otto

O, I forgot to include a link to the board.

Here it is:https://www.adafruit.com/products/2927

It is supposed to be compatable with the "bigger" board except for the Servo connectors.

Hi,

I just stumbled upon this thread.
I'm trying for a couple of days now to get the combination Teensy-LC with the smaller V2 Motorshield from adafruit to work together but had no success.
...

Hi Foyd,

hmm, one thing comes to mind, what is the default update rate of your GPS?
I use the Adafruit Ultimate GPS breakout boards and they default to 1Hz.

Regards, Otto.

@Andreas,

Thanks for the reset suggestion. My teensy 3.1 was also "dead" on the USB bus, connecting reset to GND while inserting the USB cable brought it back to life.

Thanks, Regards, Otto
