CDP sniffer for Arduino
CdpSniffino Arduino based CDP sniffer. Currently this is a work in progress. More details are on my blog http://qistoph.blogspot.com/2012/03/arduino-cdp-viewer.html Requirements: - Arduino Ethernet Shield - Serial connection - DebounceButton library (https://github.com/qistoph/ArduinoDebounceButton) Received CDP packets are (partially) interpreted and extracted information is send on the serial connection. Future plans include displaying the CDP information on an attached (I2C?) LCD.
When running the LCD branch on an Arduino Duemilenova (with ATmega328P), the Arduino seems to freeze after a few seconds. Sometimes it seems to take as much as 30 seconds, sometimes just 3. Maybe it has something to do with incoming packets that aren't handled properly.
'class W5100Class' has no member named 'getRXReceivedSize'
'class W5100Class' has no member named 'recv_data_processing'
Getting both of these errors. running a W5500 with standard ethernet.h on a ESP32
Ideas for the control of the LCD backlight:
I have an arduino Ethernet with poe module, I am using an FTDI friend for serial connectivity. I just checked out commit 020bf1e verified and uploaded to my board.
When connected to a cdp enabled switch and using serial monitor to get cdp results I get gibberish:

What could I be doing wrong? should I check out a different commit?
