LibLanc

This Arudino library allows to control a Sony Lanc enabled camera.

Since the Protocol has very strict timing requirements, the application should normally block during transmission (see LancBlocking class). This class is designed so that it loops until a complete communication exchange is completed. This is triggered by calling the loop function.

There is a non blocking variant of the Library available (see LancNonBlocking class). This variant simply checks whether there is anything to do and immediately returns. Be aware that you must call loop very quickly. It is recommended to call loop at least every 25us.

Example usage

The following example shows how LancBlocking could be used:

#include <Commands/ZoomCommand.h>
#include <LibLanc.h>

#include <memory>

// LibLanc
// by Simon Ensslen <https://github.com/sensslen>
// This example illustrates the usage of the liblanc library in blocking mode

#define LANC_INPUT_PIN 2
#define LANC_OUTPUT_PIN 3
std::unique_ptr<LibLanc::App::Lanc> lanc;

void setup()
{
    LibLanc::LancBuilder lancBuilder;
    lancBuilder.UseTwoPinPhysicalLayer(LANC_INPUT_PIN, LANC_OUTPUT_PIN, LibLanc::Phy::OutputType::PushPull);
    lanc = lancBuilder.CreateBlocking();
    lanc->begin();
}

void loop()
{
    // get next command to execute
    // call lanc.setCommand(LibLanc::CommandFactory::zoom(3));
    lanc->loop();
}
