Overview

What it does: Robotheca's summary

Reads NMEA GPS strings to record and map position information for agricultural use.
Provides up to 16 section control with unique widths, or up to 64 sections of equal width, to prevent over-application.
Outputs pure pursuit steer angles for AB line, AB curve and contour guidance.
Offers automatic headland turns (UTurn) on curves and AB lines, with loops for narrow equipment.
Can add background mapping.
Consists of two programs: AgIO, the communication hub, and AgOpenGPS, the application, which is only needed for the simulator.

Ag Precision Mapping and Section Control Software

AgOpenGPS is 2 programs. AgIO is the communication hub to the outside world and AgOpenGPS is the application. You can run either and within each, you can run the other.

You only need to run AgOpenGPS if you are using the simulator.

The software reads NMEA strings for the purpose of recording and mapping position information for Agricultural use. Also it has up to 16 sections of Section Control that can have unique widths or up to 64 same width sections to control implements application of product preventing over-application.

Also ouputs Pure pursuit steer angles from reference line for AB line, AB Curve and Contour guidance. Auto Headland called UTurn on Curve and AB Line with loops for narrow equipment. Mapping as a background can also be added.

Included in this repository is an application, and source folders.

See the PCB repo for PCB layouts, firmware for steering and rate control, machine control, GPS and simulator.
