#161538 - Decoding SBUF contents |
Am developing a project in which an 89C51 (A) sends a byte (from P3.1,(Txd)) to P3.0(Rxd) of an 89C2051 (B) (Serial comm. in Mode2, using timer1). I undertand that data is transmitted serially with LSB (least significant bit) first. Correct?
In that case if I load "01234567" in the SBUF of A it will appear as "76543210" in the SBUF of B. How do I convert the bits back to their original order? B needs the original byte to process it. Might seem like a trivial problem , but am foxed. Rishi |
