User Projects / Code Examples / Re: Use UBLOX NEO-m8N with TinyDuino?

« on: November 04, 2017, 02:19:21 PM »

I've been googling and found this UBLOX neo library:
https://github.com/SlashDevin/NeoGPS

It compiles using Ardunio on my TinyDuino with no errors, but fails to upload the sketch due to this error:
avrdude: ser_open(): can't open device "\\.\COM6": Access is denied.

I verified through Windows 10 DeviceManager that drivers for COM ports 5 and 6 are installed. 
I also tried to upload using COM 5 generating the error:
avrdude: ser_open(): can't open device "\\.\COM5": The semaphore timeout period has expired.

Went back to google and purchased another GPS..UBLOX neo-m6.  Found another article on google
for a board that looks similar to my new one:
http://www.instructables.com/id/Using-a-Hobby-Ace-Ublox-GPS-Module-Built-in-Compas/

What is troubling about this article is the GPS RX/TX pins are connected through pins
8 and 9 on an Ardunio Uno, which us supposed to be "the same" as the TinyDuino which are not
the same as the pins I used based on the TinyGPS pinouts documented in my first post.

Any insights?

I had not noticed the baud rate, but re-setting it to 38400 and ALL the others available to me had no effect.  Any other ideas?  How do you wake up a Ublox neo-m8n?  Why would it be different than the TinyGPS?

User Projects / Code Examples / Use UBLOX NEO-m8N with TinyDuino?

« on: March 19, 2017, 02:51:35 PM »

Let me start out saying I am a NewBee.  I am trying to build a GPS-IMU logger for the hotshoe of my camera.  Has anybody successfully connected the Tinyduino to a Ublox NEO-M8N GPS Module from a UAV?

<http://www.getfpv.com/holybro-ublox-neo-m8n-gps-module.html?utm_source=bing&utm_medium=cpc&utm_campaign=**LP%20-%20Shop%20-%20Flight%20Controllers&utm_term=1104001169793&utm_content=2781%20%7C%20Holybro%20Ublox%20NEO-M8N%20GPS%20Module%20%7C%20%2449.00%20USD>

I connected the GPS module to the following pins of the tinyduino protoboard:

Proto -> GPS
VCC -> VCC
GND -> GND
A0 -> RXD
A1 -> TXD
A4/SDA -> SDA
A5/SCL -> SCL

     My understanding is that the Compass is connected through the SCL and SDA pins....GPS through RXD and TXD. 

     I am trying to use the sketch from the TinyShield-GPS that uses the TinyGPS++ object.  Code compiles and loads but can't wake up the UBLOX NEO-M8N. 
     I swapped out the UBLOX with the TinyGPS shield and it works.  I have not figured out how to connect the UBLOX NEO-M8N to the UBLOX u-Center v8.24 using TinyDuino hardware.

     Any help out there?

New Product Ideas / RTK Upgrade for TinyGPS

« on: February 04, 2017, 12:39:30 PM »

I would like to see a bigger active patch antenna sized to the Tinydurino form factor for better signal quality.  Ugrading to a RTK capable GPS chip like the U-BLOX NEO-M8P or the SkyTraq S2525F8-BD-RTK to enable 1cm RTK accuracy.  Firmware should be compatible with RTKlib implemented on PCs and Android devices.  Having a project tutorial that combines the output of the GPS shield and the 9DOF shield using a kalman filter and a dead reckoning algorithm would help solve the gps signal quality issue.  The WiFi shield, or Bluetooth shield, or a new cellular modem shield would enable connection between the TinyRover and Base stations on android phones or cellular networks.

New Product Ideas / Stackable Modular case

« on: February 04, 2017, 12:13:48 PM »

make rectangular case that fits between or individual tinydurino shields for a more finished look and keep dirt out.  Could be designed to replace screws by snapping together.  Might consider a bottom and top caps.  caps could be the mechanical interface for other devices like camera hotshoe or GPS antenna domes

New Product Ideas / 38Mpix TinyCamera

Check out this surplus camera component on eBay:

http://www.ebay.com/itm/US-New-OEM-Nokia-Lumia-1020-Back-Rear-Big-Camera-Module-Replacement-Part-/370988053340

Note the ribbon connector looks similar to that on the tinyDurino......pin-outs will probable be different, and software drivers may be an issue.
