Introduction

Le CRCconnect est un dispositif qui permet d’envoyer des commandes au CRCduino à l’aide d’une manette de jeu. Le CRCconnect sert de relais pour les données; il prend les informations par USB, puis envoie l’information au CRCduino sans fils.

Il a été conçu pour permettre une utilisation flexible. Le module CRCconnect peut être attaché par velcro directement sur le contrôleur. Il peut aussi être dans la poche du conducteur et connecté à la manette par un fil USB plus long. Plusieurs écoles ont même des manettes modifiées pour intégrer directement le module. Il peut finalement être connecté à une banque d'énergie externe pour allonger sa vie de batterie.

Manettes compatibles

La beauté du CRCconnect est qu’il permet à une équipe de contrôler son robot avec des manettes de jeu standards. De cette façon, chaque équipe peut utiliser la manette avec laquelle elle est le plus confortable.

La manette doit être connectée au module CRCconnect à l’aide d’un fil USB-A vers:

• Mini-B (pour les manettes PS3), comme celui-ci de 6".

• Micro-B (pour les manettes PS4), comme celui-ci de 6".

• USB-C (pour les manettes Xbox One), comme celui-ci de 6".

Storage Mode

Like almost every electronic gadget, there is a very small current that leaks from the battery of the CrcConnect when it’s not in use, even when powered off using the power button. This undesired battery drainage can be avoided by putting the CrcConnect in Storage Mode. We recommend to put the CrcConnect in Storage Mode when you know it won’t be used for 2+ weeks. This will extend the CrcConnect battery life! Storage mode physically disconnects the battery from the control board, effectively cutting any possible leakage current.

• Storage mode is enabled when the jumper is removed from the board, or when it is plugged into the left and center pins.

• Storage mode is disabled when the jumper is plugged into the center and right pins.

Jumper OK; CrcConnect will work

Ports & buttons

The CrcConnect has 2 ports a one button on its side. From left to right:

Status LEDs

The CrcConnect has 4 LEDs that allows to learn about the state of the CrcConnect and the CrcDuino:

Robot LED

Indicates the voltage of the power supplied to the CrcDuino to which the CrcConnect is connected to, witha refresh rate of 10s. This therefore feedbacks the charge level of the 12V battery on the robot.

CrcConnect LED

Indicates the voltage of the internal CrcConnect battery. This therefore feedbacks the charge level of the 5V battery inside of it.

Communication LED

Indicates the connection quality between the CrcConnect and its paired CrcDuino. Is also used to indicate a successful link between a remote controller and the CrcConnect.

Typical interference causes include and are not limited to: too much metal around the CrcDuino, robot frame electrically connected to the battery negative pole (lose wire, faulty wire isolation), etc.

Charge LED

This LED, on the backside of the CrcConnect, is lit when it's charging, and OFF when not charging.

Power management

The CrcConnect module can be recharged throught the Micro-USB port. It can even be recharged when in use!

No need to worry about recharging the remote controller itself. The remote controller, when connected to a CrcConnect module, is powered by the CrcConnect internal battery pack.

Auto-shutdown function

Auto-shutdown functions have been programmed into the CrcConnect to avoid permanent internal damage.

Voltage shutdown

If the internal battery voltage falls beneath a certain threshold, the CrcConnect won’t power up or will shutdown immediately after being powered up.

Temperature shutdown

If the internal temperature gets so hot that it might lead to permanently damage the internal battery, the three main status LED will flash Orange 5 times and the CrcConnect will automatically shutdown right after.

Button and joystick mapping

The remote controller buttons and joysticks state can be retrieved using CrcLib::ReadDigitalChannel() and CrcLib::ReadAnalogChannel() using the appropriate nomenclature.

The following pictures show the physical mapping of the different members of the enum classes for typical remote controller arrangements.

Still not sure? Upload the following code into your CrcDuino and open up a Serial Monitor at 2000000 baud to witness the state of the different buttons of the remote controller on your computer screen.

//CrcConnect Remote Controller Test Sketch
//Valid using CrcLib_1-1-0_Release

#include <CrcLib.h>
//------------------------------------------------------------

void setup() {
  // put your setup code here, to run once:
  CrcLib::Initialize();
  Serial.begin(2000000);
}


void loop() {
  // put your main code here, to run repeatedly:
  CrcLib::Update();
  Serial.println();

  if (CrcLib::IsCommValid())
  {
    CrcLib::PrintControllerState();
  }
  else
  {
    Serial.print("No remote controller successfully communicates with the CrcDuino");
  }

}

  Introduction

  The CrcConnect is a device that allows to send commands to a CrcDuino using a remote controller. The CrcConnect serves as a data relay; it takes information from a controller (using a wire), and sends this information to a CrcDuino wirelessly using a pair of Xbee Modules.
