Here, you will learn how to interface 16×2 LCD to PIC18F4550 microcontroller which is of family PIC18F. PIC18F4550 is an 8bit microcontroller and uses RISC architecture. PIC18F4550 has 40 pins in PDIP (dual in line package) and 44 pin in TQFP (Quad flat package). You may get detailed information about this circuit by reading the post - How to Interface 16X2 LCD with PIC Microcontroller.
<p>Hello I need to use parallax RFID Reader Serial with WiFi<br>module esp8266 and LCD using pic16f877a. every time I run the circuit the RFID<br>doesn&rsquo;t work</p>
<p>The code you gave does not seem to be working fine. It compile with no errors but does not work on the hardware. I found a well explained working code for <a href="http://innovatelogics.com/blogs/tutorials/15072977-interfacing-lcd-with-pic18f4550" rel="nofollow">Interfacing LCD with PIC18F4550</a> and circuit diagram along with software simulated video.</p>
