RTCzero library found here: https://github.com/arduino-libraries/RTCZero

Hi,
    I tried modifying the sample TinyGPS shield sketch to write the encoded NMEA sentence to a file on a microSD card.  I think the problem is in the modified smartdelay routine that never finds a satellite fix....or a valid NMEA sentence.  Hardware I am running:
    TinyScreen+ processor
    TinyGPS Shield modified to have chip select pin set to 8
    Tiny SD microSD shield

    Anyone see the problem?

General Discussion / Micro SD Documentation
« on: March 15, 2018, 11:24:30 PM »
Hi,
    Could you verify the MicroSD pin documentation posted on you web site matches the hardware implementation?   I think I read that the CS data line in the SPI interface should be unique to the individual device and the shared data lines (MOSI, MISO, and SCLK) should be connected to the same pins of when using multiple SPI devices?  Looking at the Tiny Circuits Micro SD shield documentation, I noticed that pins 11 (labeled SCLK) and 13 (labeled MOSI) are swaped relative to the documentation for the Nordic BLE, BLE St, WiFi, and other communications shields in the Tiny Circuits store.  If the MicroSD documentation is correct, then I think it means the MicroSD shield is not compatible with the other SPI devices.

TinyDuino / Re: IDE Uploader Issues
« on: February 25, 2018, 02:36:33 PM »
I to am getting the same error when building a sketch for my TinyScreen+ SAMD board:

C:\Users\ranal\AppData\Local\Arduino15\packages\TinyCircuits\hardware\samd\1.0.7\cores\arduino/Arduino.h:47:17: fatal error: sam.h: No such file or directory

 #include "sam.h"

Difference is that I was running the Ardunio IDE 1.8.5 on Windows 10 when it happened.  Can you tell me what files I have to place where to fix this issue?

General Discussion / TinyScreen+ SmartWatch Compile Error
« on: February 15, 2018, 09:11:30 AM »
I tried to compile the standard TinyScreen Smartwatch sketch on the Learning website without success.  After much searching through the forum, I found Ben Roses sketch enclosed in a reply to a person having similar difficulty.   The header in Ben Rose's sketch identifies the version as:

//  TinyCircuits TinyScreen+/NRF8001 Smartwatch Example Sketch
//  Last Updated 3 March 2017

Is there a latter version somewhere? When I compile it I get the following compiler error:

F:\TinyDuino\TinyScreen_Smartwatch\TinyScreen_Smartwatch\TinyScreen_Smartwatch.ino:25:21: fatal error: RTCZero.h: No such file or directory

 #include <RTCZero.h>

                     ^

compilation terminated.

exit status 1
Error compiling for board TinyScreen+.

...with your motor control boards....and some design work, you could build a Lidar Scanner!

New Product Ideas / Universal Modular Sketch Template
« on: January 28, 2018, 11:31:42 AM »
Hey!  You used compiler directives to make your sketches compatible with your processor boards.  Why not use compiler directives to activate portions of a "universal" sketch of all tiny circuit shields that can be toggled using compiler directives based on the users tiny circuit configuration.  It sure would be easier for us to customize and would solve compatibly issues right out of the box!

I was thinking that 3D printing an individual case for each board with custom cutouts or clear windows where appropriate.  These would be stacked with pins replacing the screws/spacers now used.  The TinyScreen or TinyScreen++ would be one of the ends of a stack.  Battery could be in a housing at the other end?  The TinyGPS antenna could be a little 3D printed rotodome stacked on one side of the stack to orient it properly.....IMU, compass too!...a side stack!  Got to use the ribbon connector to connect it all together. All modular and customizable....compatible with LEGOS!?

General Discussion / TinyScreen+ Nordic BLE Paring Error
« on: January 14, 2018, 10:52:26 AM »
Hi,
     I have a TinyScreen+ and a Nordic Bluetooth Low Energy TinyShield in my stack. I successfully compiled and am trying to run Ben Rose's "TinyCircuits NRF8001 UART Example Sketch updated" 27 May 2016 on the TinyScreen+

The only device I did not recognize in the Bluetooth setup on my android phone is named "URT". When I try to pair to the device named "URT" on my cellphone it says "Unable to communicate with URT".

I had a strange problem with the Ardunio IDE standard Serial Terminal flip-floping between COM 9 and COM 10 identified for the TinyScreen+ when the code was uploadig.

When I am successful uploading the code, the "standard" Serial Monitor from IDE outputs:

Evt Connected
Evt Pipe Status
Evt Disconnected/Advertising timed out
Advertising started

when set at either 115200 and 9600 baud rates.

Any idea what is going on?

New Product Ideas / Upgradeable GNSS shield
« on: December 17, 2017, 09:05:48 AM »
Many of the GNSS solution providers like UBLOX and Telit have families of devices with the same pin-outs and form factors supporting various features.  In the case of Telit the SL869, SL869-V3, SL869-ADR, and SL869-3DR.  UBLOX has the neo-5, -7, and -8 generations of families that are pin=compatible upgrades.  Personally, I am interested in Untethered Dead Reckoning (UDR) as implemented in the UBLOX Neo-8U and the Telit SL869-3DR; and RTK as implemented in the UBLOX neo-8T.  It would be cool for TinyCircuits to offer an upgradeable GNSS shield using one of these pin-compatible GNSS families...especially if you implemented the shield with a socket so it could be tailored by the customer for their application!
