Methods

void ALLeds::createGroup(const std::string& groupName, const std::vector<std::string>& ledNames)

Makes a group name for ease of setting multiple LEDs.

Parameters:
  • groupName – The name of the group.
  • ledNames – A vector of the names of the LEDs in the group.

Python:

# Replace "127.0.0.1" with the IP of your NAO
leds = ALProxy("ALLeds","127.0.0.1",9559)
# Create a new group
names = [
"Face/Led/Red/Left/0Deg/Actuator/Value",
"Face/Led/Red/Left/90Deg/Actuator/Value",
"Face/Led/Red/Left/180Deg/Actuator/Value",
"Face/Led/Red/Left/270Deg/Actuator/Value"]
leds.createGroup("MyGroup",names)
# Switch the new group on
leds.on("MyGroup")

C++:

boost::shared_ptr<ALLedsProxy> leds = boost::shared_ptr<ALLedsProxy>(new ALLedsProxy(getParentBroker()));
// Create a new group
std::vector<std::string> names;
names.push_back("Face/Led/Red/Left/0Deg/Actuator/Value");
names.push_back("Face/Led/Red/Left/90Deg/Actuator/Value");
names.push_back("Face/Led/Red/Left/180Deg/Actuator/Value");
