i have to transmit data through P1.1 pin. Why specifically that pin? Why can't you use a UART? Must it be only a single pin, or could you add another for a clock signal? How much data? How fast? How often? Does the receiving device impose any restrictions? Does the transmission medium impose any restrictions (eg, some require an average DC level of zero)? As Richard said, Manchester encoding could be an option: http://www.8052.com/forum/read.phtml?id=140213 You could implement the transmit half of a software UART You could look at how something like Dallas 1-WireTM works. what should be the code in Bascom8051 ? Impossible to answer on the information given. Even with sufficient information, I'd echo Richard's doubts as to whether BASIC (or, in fact, any high-level language) is appropriate: http://www.8052.com/forum/read.phtml?id=140213 |
