Hi Dear Friend ,
Do You Can Description About Code?

 

[ckshivaram]

there is description for every line.... please look into that.. what description you need???

have you done simple serial comm programs for avr controller?????

if not write a simple program for serial comm and transmit some data to lcd.....

 

[hamsaeed]

Hi My Friend
I don't simple serial comm programs for avr controller?

Dear Friend ,
Is It Project For ATMEGA 32 ?

---------- Post added at 11:29 ---------- Previous post was at 11:25 ----------

Where Is My Friend???

 

[ckshivaram]

i am in office and cant spend time with you....download AVR tutorials and do some example programs given in it or see the example in the avr installed directory for serial communication.... i cant be online for more time.....
