PIC16F877A + Serial LCD issues

[nem]

Hello all and thanks for reading!

I am very new to PIC programming and am having some issues with a recent purchase of LCD. I have the following:

It is a serial 16X2 LCD. I have information on how to connect a parallel LCD with my PIC but not how to interface this LCD properly...there are only 3 pins --> VCC, GND, and RX. RX is the signal pin.

I just realized that I may not even need the serlcd-v2.c in my project space...is this simply the code provided that is on the PIC16f688 chip that translates the parallel LCD into a serial LCD?

So would I simply need to obtain a serial routine for my PIC16F877a and output data according to the data sheet of the LCD through a single output pin? I would appreciate any clarifications or confirmations! Thanks

**EDIT**

I realize that I really don't know what I'm talking about with this application, but I'm trying to grasp it. I have been able to interface with the LCD through using the usart_write() function but am only able to transfer what appears to be garbage on the LCD side. i have tried sending integers, single characters, the hex value for the characters. None of which has worked. I can post some code if that would be helpful, but I'm shooting in the dark here. Thanks

Hi,

You should connect TX line from MCU to RX line on your serial LCD.
Also you should read carefully datasheet for your serial LCD.

I can suggest you that you should search on our forum topics about serial LCD.
I believe that you will find a lot of useful information on our forum.
