Hi how can i send a hex data to a single port as serially
for example
i need to send the following data to
P0_1 = oxff;
how can i do this simply
please help me
Sending 0xff serially means to set the port to constantly "1".
If 0xff is just an example for an arbitrary value, you should use a shift instruction in your favourite programming language and run it in a loop eight times, sending the carry bit to the port (or the lowest/highest bit before the shift, whatever you prefer). To make the data stream readable to anyone, you would want to apply a specific time delay for each bit (asynchronous serial transmission) or send a clock along with the data (synchronous serial transmission).
