Hello Dharmani,

I have tried to build simple temperature controller with AVR, this is my project, but failed. The AVR based controller with keypad and LCD display, I'll give a teperature limit, lower and higher through keypad. A sensor (LM35) connected to port measures temp and controller compare with the range and will give me warning..those are whole bunch of task my comtroller will do..pls help me with schematic and code in C.
Thanks for now.

Regards.

i already compile it with avr studio.i choose avr 32 simulator but when i try to run it, there are lot of errors.
when i run it,the errors show that PORT A,PORT B,PORT C,PORT D,MCUCR and TIMSK are undeclared.

Please, sir send to me the correct .h files and how to include it because i am not good to work with AVRstudio because i am working with Micro c.

Hi
All your posts were very much useful to me. I am working with AVR controllers for the past 2 months. I have successfully completed the 8bit LCDHD44870 display, But I am not getting the result with 4bit mode. Can you provide me some example codes, and some explanation regarding the same. I am working with AVR studio 4. Looking out for your help

Thanks and regards
