Description

GEO-ACQ is an acquisition program

• GPS
• Echosounder
• OTT Radar

running on a Raspberry Pi

Windows prerequisites

Install MinGW with Msys. If you use Visual Studio Code, configure the terminal shell with msys. See: https://code.visualstudio.com/docs/editor/integrated-terminal#_configuration

Add the following line to your user/setting.json file:

"terminal.integrated.shell.windows": "C:\MinGW\msys\1.0\bin\bash.exe",

You must define Windows env variables :

GOBIN=%USERPROFILE%\go\bin

and

GOPATH=%USERPROFILE%\go

and add the C:\MinGW\msys\1.0\bin directory to your Windows path.

Test inside terminal:

make --version GNU Make 3.81

Development

Clone the go-serial git repository directly into your src folder under src/go.bug.st/serial.v1 and checkout the branch v1.

cd $GOPATH
mkdir -p src/go.bug.st/
git clone https://github.com/bugst/go-serial.git -b v1 src/go.bug.st/serial.v1
go test go.bug.st/serial.v1

Install and use package:

A fork of github.com/pilebones/go-nmea:

• github.com/jgrelet/go-nmea
• github.com/creack/goselect
• github.com/pborman/getopt/v2
• github.com/BurntSushi/toml

Compilation

Under development:

> go build

To build all plateform targets under production:

> make

To build specific targets (linux/amd64, windows/amd64, linux/arm or darwin/amd64windows) under production:

> make linux/arm
...
>  ls -l *linux-arm*
-rw-r--r-- 1  nmea-proto-linux-arm

Usage

> ./nmea-proto-linux-arm -h
Usage: c:\users\jgrelet\go\src\bitbucket.org\jgrelet\raspberry\go\dev\dev.exe [-dehlv] [-c nmea.toml] [-s value] [-t value] [parameters ...]
 -c, --config=nmea.toml
                    use specific configuration .toml file
 -d, --debug        Display debug info
 -e, --echo         Display processing in stdout
 -h, --help         Help
 -l, --log          Write log, defaut is true
 -s, --simul=value  Simulate: GPS, Echo-sounder or Radar
 -t, --trace=value  Display terminal for: GPS, Echo-sounder or Radar
 -v, --version      Show version, then exit.

Run in simulation mode, with error log to stdout and terminal mode:

> ./under production: -e -s gps,sounder -t gps,sounder -l -c linux.toml
