Cmd

Simple command line processor (for Arduino)

To use, create an array of Cmd::Event objects, terminated by an entry of all nullptrs.

const Cmd::Entry gCmdEntry[] =
{
  { Cmd::Args,  "args", "",           "Displays arguments passed on command line" },
  { Cmd::Help,  "help", "[command]",  "Displays help for a given command (or all commands)" },
  { nullptr, nullptr, nullptr, nullptr }
};

The functions should have a function prototype which looks like:

void SomeFunc(int argc, char **argv)
{
}

argv will be a null-terminated array with argc entries. The very first entry will be the command that was entered.

Create a Cmd object (or an object derived from Cmd):

Cmd gCmd(gCmdEntry);

For now, add a call to:

  gCmd.Run();

in your loop function. This requirement will go away once Serial events can be used.

To override which serial port is used you can either create a variable called Serial in your main app, ala:

HardwareSerial2 Serial;

or you can use an object derived from Cmd which overrides the IsCharAvailable, GetChar, and PrintChar methods.
