Arduino UNO - Adafruit FingerPrint

Projects Programming
1

Good morning, I'm working on a project with Arduino Uno, which integrate WebServer, ClientServer, biometric reader and LCD. I use the Ethernet Shield W5100 LCD KeyPad Shield (SKU: DFR0009) and Adafruit FingerPrint. Previously, I had done a code in which did not use the fingerprint, however, recently decided to integrate the fingerprint system, but I'm having some problems, I'll quote them:

  1. I can not use the integrated fingerprint with the webserver, for reading the digital, however, can use the webserver to register property in the digital fingerprint.

  2. Arduino hangs when running code that has integrated webserver and biometric reader.

I wonder if there is some sort of incompatibility between components, for testing each one separately they estam working perfectly.

Then you need to post links to the hardware, not part numbers and text.

What code? I don't see any code.
