Biblio...Serial(3pm)

💖 Biblio::RFID::Reader::Serial — bestie edition 💖

okay so this is Biblio::RFID::Reader::Serial, from the User Contributed Perl Documentation section, and she's on 3pm. she's the base class for serial RFID readers — and also for serial-over-TCP ones, because she contains multitudes ✨

🌸 NAME 🌸

Biblio::RFID::Reader::Serial — the base class for serial readers, or serial-over-TCP readers. she's the blueprint the other reader classes build on, and she ate 💅

🎀 METHODS 🎀

🦋 new

Opens the serial port (if that's even needed) and inits the reader. that's it, that's the whole job. she's lowkey doing the most important part 🫶

🦋 port

she goes looking for USB serial ports at /dev/ttyUSB* and regular serial ports at /dev/ttyS*, and tries to open them. no cap, she's out here doing a whole vibe check on your hardware 🔥

my $serial_obj = $self->port;

only want her to try one specific device? iconic, just set the environment variable:

RFID_DEVICE=/dev/ttyUSB1

and if you're feeling fancy and want a serial connection over a TCP socket instead, you have to export this environment variable:

RFID_TCP=hostname:port

fr fr, it's hostname:port — the hostname, then a colon, then the port. don't skip the colon bestie 😭
