Raymaxime-display

Raymaxime is a multifunction display dedicated to sailing more specifically for sailboats, it allows to display values ​​(ex: wind direction, wind speed, heading, GPS speed, etc).

The Raymaxime was created with an M5Stack so it has a LCD screen of 320x240 pixels, 4 buttons including a destiny to restart the device, a WiFi chip and Bluetooth, a 150 mAh battery that can be upgraded, a USB type-C port and an SD card reader.

The M5Stack is connected to a Wi-Fi Raspberry pi 3, which has the Openplotter operating system, the raaspberry also has a GPS and an ultrasonic wind vane.

SignalK values ​​that can be retrieved

SignalK	Json
Heading	ap.heading
GPS speed	ap.gps_speed
Wind speed	ap.wind_speed
Wind direction	ap.wind_direction
Pilot mode	ap.mode
Pilot status	ap.mode

Get started :

Step 1 : Go to Raymaxime-display folder and src folder and modify WiFiParameters.h file with your parameters.

Command for Linux :

nano ~/Raymaxime-display/src/WiFiParameters.h

#define WIFI_SSID "Your_SSID"       //ex: Wifihome
#define WIFI_PASSWORD  "Your_Pass"  //ex: Mypassofmyhome22
#define TCP_HOST  "Your_TCP_Host"   //ex: 192.168.0.2
#define TCP_PORT Your_Port          //x: 11111

Step 2 : Go to Raymaxime-display folder and src folder and modify Setup.h file and uncomment the default pilot mode that you wish and comment the active mode.

Mode	Value
Compass	compass
GPS	gps
Wind	wind
True wind	true wind

Command for Linux :

nano ~/Raymaxime-display/src/setup.h

//Choose your default mode of Pypilot

const char* VALUE_PILOT_MODE = "compass";
//const char* VALUE_PILOT_MODE = "gps";
//const char* VALUE_PILOT_MODE = "wind";
//const char* VALUE_PILOT_MODE = "true wind";

Step 3 : In this same file choose the parameters of the display

‼️ : If you modify this file you must also modify the last 4 lines in the file main.cpp so that it matches.

const char* TEXT_ZONE_1 = "WIND DIR";
const char* TEXT_ZONE_2 = "WIND SPEED";
const char* TEXT_ZONE_3 = "HEADING";
const char* TEXT_ZONE_4 = "TARGET CAP";

nano ~/Raymaxime-display/src/main.cpp

display_text(TEXT_ZONE_1, Wind_direction, 1);
display_text(TEXT_ZONE_2, Wind_speed, 2);
display_text(TEXT_ZONE_3, True_heading, 3);
display_text(TEXT_ZONE_4, Target_heading, 4);
}

Step 4 : In this same file choose the value of TACK .

‼️ : The value of the TACK enter in this file is gale : your_final_value - 10°.

const int TACK = 90; // your number + 9 + 1 || here 90 + 9 + 1 = 100°.

In my exemple my final TACK is 100°.

Controling autopilot :

The autopilot of pypilot will be activated/desactivated when "button B" was released.

Button A increases the target heading by +1°, +10° and +100°

Pressed For	Result
500 ms	+ 1°
1500 ms	+ 10°
5000 ms	+ 100°

Button C increases the target heading by -1°, -10° and -100°

Pressed For	Result
500 ms	- 1°
1500 ms	- 10°
5000 ms	- 100°
