TinyDuino Processors & TinyShields / Re: Grief with failing Tinyduino USB boards

« on: April 01, 2015, 03:12:29 PM »

Hi Phil, if you're using the motor controller board, let us know how it's wired up, along with what revision USB and main processor board you have. A picture of the setup can help a lot.

I haven't heard about any recent USB TinyShield failures, so I would definitely like to figure this one out.

I haven't seen or heard of that message in the nRF apps. Try the nRF UART v2.0 app, which should allow you to connect and send a message to the watch- if you send a message starting with 1 or 2, it should display on the watch. Make sure you're using the latest code on codebender, and please let us know what phone and operating system version you have if it still doesn't work.

We've updated the Hackster examples to use the latest library, sorry about that! I'll take a closer look at your code soon and see if I can figure out what's going on.

You're using a very early version of the TinyScreen library. The newest version is at https://github.com/TinyCircuits/TinyCircuits-TinyScreen_Lib or our CodeBender examples. I think the version you have is old enough that the SPI is managed in a manner that can conflict with the SD card, so see if just changing the library fixes your problem and let us know.

The time doesn't tick over without a sync because of the "&& timeStatus()==timeSet" condition that is checked before updating the screen when it's on. Once it has been connected to the Android app or you remove that condition, it will update every second when the display is on until it shuts off after five seconds- you can change displayUpdateInterval and sleepTimeout if you don't like that.

If you can post more details about your Android phone and why the app is crashing, I can try to fix it. Once the app is connected, it will set the date/time and send basic text/phone call notifications to the watch. That's all the example does for now.

jpencausse, you need to download the Time library http://playground.arduino.cc/code/time and our TinyScreen library at https://github.com/TinyCircuits/TinyCircuits-TinyScreen_Lib and put them in your libraries folder.

WakeArray, thanks, and the software is at https://www.nordicsemi.com/eng/Products/2.4GHz-RF/nRFgo-Studio

You'll also need the Nordic's library at https://github.com/NordicSemiconductor/ble-sdk-arduino/releases

Open nRFgo Studio, click on nRF8001 Configuration, then open the xml file under the ble_uart_project_template in the library. You can change the advertising name under GAP settings. Then generate services.h and replace the old file in your sketch folder.

Overkill procedure for changing the name, but that's that. It looks like it's possible to change it during run time, but I can't find the function that sets the name. For now, I've just changed the CodeBender example to advertise as BLEWatch instead of URT, at least.

Unfortunately those bitmaps were created by hand. It should be possible to use GIMP or ImageMagick, but I haven't yet had time to look into it.

TinyDuino Processors & TinyShields / Re: TinyDuino BLE two BLE communication

« on: March 16, 2015, 06:58:54 PM »

Our BLE112(but not our newer NRF8001) shields can communicate between each other. I attached a very rough example of code for a controller and tank/robot, it should give you an idea of what's needed.

SD cards share the SPI bus with TinyScreen, so how and when each is used is important. Can you post or attach the full sketch?

TinyDuino Processors & TinyShields / Re: GPS Data and Failure of Tinyduino to Turn Back On

« on: March 16, 2015, 06:51:51 PM »

Hi Jimmy, a couple problems:

'Loaded no data' issue is because some of the NMEA sentences have a different header than what Google wants. There's also sentences with missing characters. Our newer code for V2 GPS chipset should fix those:

https://codebender.cc/sketch:60928

The power issue sounds like the GPS module isn't being switched on correctly. Let us know if the newer code fixes that.

Using sleep mode requires a good understanding of how the atmega328p works, here's some(lots of) information to get you started:

ainfield, we do not yet have an iPhone app, it's something we'll have but I don't know exactly when.

jpencausse, note that the name in the BLE advertisements which will show up in the app is URT, due to the Nordic virtual UART setup. The date/time update should happen automatically after a connection is made.

ble_rx_buffer is filled in aci_loop() when there is new data.

The name/ID is set through the Nordic setup code which needs to be generated with their software.

Hope this helps you get the demo working.

« on: March 16, 2015, 05:50:34 PM »

Unfortunately our new NRF8001 based BLE shield is not able to send iBeacon compatible advertisements. Our older BLE112 based shield will require being reflashed with a TI CC Debugger.

We have an example Android app that just went up. It's currently available for testing at https://github.com/TinyCircuits/TinyCircuits-TinyScreen-Android-App

It shows how to connect and pass simple notification data- texts and incoming calls at the moment.

Our example watch code is available at https://codebender.cc/sketch:91833

Unfortunately 1632 cells can't support the current draw from the OLED. A small lithium polymer battery is the way to go if you're able to solder one on.
