First of all you have to decide which gsm module you want to connect to your uC. I might help you in case of 16F877 (16F887) micro and Telit GM862 gsm module.

We will do it step by step...
first search to forum for lcd interfacing, and u will get code on - The Online 8051/8052 Microcontroller Resource - for LCD interfacing...
Later we will deal with gsm interfacing..

I am doing a automation project to unlock door via SMS.
I am using an Arduino UNO and SIM300 with a max232circuit in between.
The gsm module to hyperterminal interaction is working, ARDUINO - MAX232 to hyperterminal is working.
But when i combine them all, I don't get any result.
I am using SoftwareSerial mySerial(2, 3) in my program.

I am facing a problem interfacing ATMEGA32 & JHD161A(16x1) LCD.On searching the net, i have found 2 types of connections:
1. Connect DB4-DB7 pins of LCD to a port & RS,RW,E to same port (DB0-DB3 are not connected.)
2. Connect DB0-DB7 to a port & RS,RW,E to other port.
I have tried both but have failed to get anything displayed on my LCD.
