You can use a 16x2 LCD display working with serial or I2C interface.
A basic 16x2 display is hard to use directly with ldmidro because it use many pins and has timing constraints.

claro, creo que no especifique, quisiera usar el pic 16f72 con comunicación i2c para enviar textos, pero parece que no es compatible en ldmicro y si no es compatible usaría otro pic 16f877 como lo haria, un ejemplo

PIC16F72 does not support the master I2C mode required to drive a display. You can use PIC16F876 or 877 instead.

To do it you'll need ldmicro32, external libraries, and HTC Compiler for Pic16.

All you need is on Github:

Here's attached an example of ladder working with PIC16F876 driving an I2C 16x2 lcd display..
