My name is T.D.S.Varma. I am unable to complete my project in 8051 i.e, Microcontroller. I am unable to find some Library codes I think these are related to 8051 and 8052 mostly. If anyone find them please give me the website or the syntax of those functions. Kindly send the reply as early as possible.
my mail id is durgasrinivasvarma@yahoo.co.in


______________can you elaborate the library codes:_______________________
