# ATTMapper (WIP)

A TTN Mapper based on the ATTNode v3.

**Everything in this repository is work in progress, use at your own risk!**

## Hardware

  * Attnode v3 with PCB-Edge SMA Antenna Mount
  * Powerpack, LiPo Cell (500mA), LiPo Charger Board (You can use any 3,3V Power Source)
  * NEO M8N GPS Breakout (Any 3.3V-Capable Module which is NMEA-Compatible should work)
  * SSD1306 128x64 OLED-Display
  * Button

### Connections

Connect the AttNode and Modules as follows:

#### GPS

| ATTNode | Module | 
|---------|--------|
| Vin     | VCC    |
| GND     | GND    |
| Tx      | RX     |
| Rx      | TX     |

#### OLED

| ATTNode | Module | 
|---------|--------|
| Vin     | VCC    |
| GND     | GND    |
| SDA     | SDA    |
| SCL     | SCL    |

#### Button

The Button has to be Connected between PC2 and GND on the ATTNode

## Software

This repository contains the PlatformIO project with the mapper firmware. Copy config.example.h to config.h and insert your keys and DeviceID from TTN. Compile and upload as normal (See AttNode v3 dokumentation for details).

### Usage

If a Button is connected you can use the following functions:

  * **Short press:** Schedule an imideate send, regardless of interval | In Setup Mode - cycle through Settings or Change Activated Setting
  * **Long Press (>1s):** Enter Setup Mode, Activate a Setting in Setup Mode

In Setup Mode a '>' in front of a Line identifies the selected option, a '>>' identifies an activated setting (can be changed by short press). Use long press to deactivate an activated setting
