General Discussion / Re: TinyCircuit Bluetooth Sample Code UART
« Last post by lennevia on January 13, 2020, 01:10:28 PM »

I used a TinyScreen+ and STBLE TinyShield to test the example included on this Learn Page: https://learn.tinycircuits.com/Communication/Bluetooth-Low-Energy_TinyShield_Tutorial/

and I did not encounter the same error.

Can you tell me more about what hardware you are using, and what you have selected under the Tools menu in the Arduino IDE?

Thank you,

Somehow, TinyCircuits projects would be just soooo much cooler with a wireless charger. Electric toothbrushes have tiny wireless chargers. Why can't we?

Pleeeeeeez? (for water-resistant projects!)

TinyDuino / SmartWatch hangs
« Last post by Emin on January 11, 2020, 10:55:12 AM »
Just assembled the SmartWatch kit. Before doing any tinkering (the intention is to change the functions and what is displayed) I obviously tried the standard sketch / software. After adding the missing libraries (the bluetooth board library and the Time library) it compiled and uploaded without any errors. However, the watch hangs, sometimes just after powering on, sometimes a few seconds later. I was never able to complete the changing of date and time in the menu, as it hanged during this. Unless it was on that menu some red stripes were displayed in place of one of the characters.

Is this a software issue or can this indicate that one of the boards in my kit is damaged?

General Discussion / The Hap-eRanger: a haptic TOF ranging support cane
« Last post by karl_lew on January 10, 2020, 04:00:28 PM »
I'm gradually losing my sight, so I decided to work on a project that might help in the years to come.

By way of introduction, I'll start this post with a description of what blind people do to get around. Blind people generally use "support canes for the visually impaired." These are those long, collapsible red-and-white canes one sees on the streets. These canes are remarkable devices on their own and afford tremendous mobility to people who might otherwise suffer alone in their house. The support canes represent freedom.

Yet there is one significant drawback to the support cane. As with most drawbacks, it is related to what the support cane does best. Support canes reach out and tap objects. They are touch wands that tap their way through our world, allowing us to perceive what is out there. And that tapping is horrible when one taps a person. That tapping violates their personal space. This means that blind people cannot freely use their support canes in crowded spaces with people whose backs are turned to the support cane. There will be awkwardness and embarrassment as people are tapped from behind.

I've long been a fan of TinyCircuits. And when I learned about the Time-of-Flight (TOF) ranging sensor, I was quite excited. HERE is a sensor that can be used to build a touch-less support cane. Indeed, with all the Wirelings, all of a sudden we've got ALL the parts needed to make such a support cane.

I call it the Hap-eRanger https://github.com/oyamist/om-ranger. It is a haptic electronic rangefinder that uses the TOF Class 1 laser to emulate a support cane. The Hap-eRanger uses a LOT of TinyCircuit parts. It uses the TinyZero MCU with that critically needed 3-axis accelerometer. It uses the LRA Driver for haptic feedback. It uses an RBG LED. It uses a 500mAh LiPo battery. It has a 3D-printed case.

The other thing that may be of interest is that the Hap-eRanger uses Operating system Milli (OMilli), which basically turns your Arduino MCU into a multi-threaded operating system to support all your TinyCircuit devices. :D

Anyhow, RSVP if interested and we'll take it from there! :D
General Discussion / ROMs

Short and simple. I am new to all of this and I was wondering if it's possible to put Game Boy emulators & ROMs on the pocket/tiny arcade.
TinyDuino / Text got scrambled on Tinyscreen+
« Last post by Rio6 on December 21, 2019, 06:05:39 PM »
Yesterday when I was trying to reset my Tinyscreen+ by using a needle to flick its power switch (because the case made it hard to do it with my fingers). It was a bit clumsy and I may had shorted some connections in the process. After that, the text on the bottom part of the screen become scrambled as shown in the attached image.

Does anyone have an idea on what caused that and if it's fixable?

Thanks for any help
TinyDuino / EAGLE libs for TinyZero boards

Hey there,

is it possible to download the TinyCircuits EAGLE library?

Thanks in advance,
TinyDuino / Re: IR thermal camera wireling overlay

So you would draw it after everything else. You could use writePixel, drawPixel, drawLine, drawRect... etc..

For maximum framerate, you could 'draw it yourself' in the offscreen buffer before it gets copied to the screen.
TinyDuino / IR thermal camera wireling overlay
« Last post by ahobbes on December 17, 2019, 01:31:11 PM »

I’ve been experimenting with the IR thermal camera and my tinyscreen+.

The code from tinyjohn has helped me a lot. However, I’m trying to overlay simple graphics onto the IR image displayed on my tinyscreen. Just a static triangle. Can anyone help me out with a start to how I would code this?

Here is a link to tinyJohn’s post.
