sir i want to know about the role of microcontroller here...
Reply to this  


Microcontroller ebooks Projects codes examples Ajay Bhargav | 18 Jun : 07:25
role of controller is to control LCD, Control and read ADC, do calculations on digital value and convert it to readable voltage.

I wanted to compile the lcd.c file to hex, but when I compile it using sdcc there is an error.
lcd.h:4:20: REGX51.H: Invalid argument

is there a solution.
Reply to this  


Microcontroller ebooks Projects codes examples Ajay Bhargav | 15 Dec : 03:47
use keil, or change header file for SDCC. there might be other changes too. Use forum incase of help.

Microcontroller ebooks Projects codes examples Anonymous | 15 Dec : 08:49
Thanks for your reply,I just started using keil.....I was using SDCC and Top view simulator to simulate my project and it was going fine, but all of sudden there is no output in the lcd ....is there better option for top view simulator
