i have an 89S52, i need to read from the pc 2 bytes.
1 in ASCII and 1 of binary 8 bit. As far as the 8051 UART is concerned, they are all just 8-bit bytes. However, the PC's configuration may restrict sending non-printing ASCII codes - are you sure that the PC is correctly configured, and is correctly transmitting both bytes? my question is if i need any delay between the readings? What do you mean by "readings" here? - between the 2 bytes of each pair? - between pairs? - or what? right now it dosent work. That tells us almost nothing! You need to describe precisely how it "doesn't work" - what, exactly, happens? What testing & debugging have you done? What conclusions have you drawn?
