SerialPrintChannels Usage

Creating the printer

Create your print object:

SerialPrintChannels print;

By default, the active capacity is 10 channels.

You can also choose a different default capacity:

SerialPrintChannels print(16U);

Configuring the printer

The active number of printable channels can be changed with:

print.setCapacity(16U);

The separator used between fields can be changed with:

print.setSeparator(":");

To remove all registered channels:

print.clearChannels();

Connecting channels

Channels are connected directly from float variables using:

print.connectChannel(variable, "channel_name");

For example:

print.connectChannel(app.variable.V_high, "V_high");
print.connectChannel(app.variable.speed_ref, "speed_ref");

Channels are printed in the same order as they are connected.

Printing the header

To print the registered names:

print.printHeader();

Printing the values

To print the current values:

print.printValues();

Each call prints one full row terminated by \n.
