hi...
Ive made an interface in which PIC 16F877A and ATMEL 8051 communicate serially.
PIC has an option in PIC Basic to make the levels True(0-5V) or Inverted(RS-232) levels.
The problem is that PIC is not taking the input from 8051 directly(using True levels). I have to use an additional MAX-232 IC to convert level of 8051 to RS-232 and then PIC receives the data( then i also change PIC levels to inverted).
ive tried using another 8051 in place of PIC .... and that receives the data form the first 8051 correctly.... but PIC doesnt.
Can anyone suggest wat shud be done ??
