qeustion

Dear friends,

Today my question is, what kind of communication protocoll is used through the (intra-processor) jack.

Is it RS-232?

I must connect an oscilloscope to see it, but I need a few weeks.
It could be very useful to connect any other apparatus, and so, very useful for electronic profesionals (and even hobbyists ;))

Thanks!!!!

    1 - we don't know if the OP is talking about I2C.
    2 - RS232 does not automatically imply any XON/XOFF.
    3 - why do you think I2C at say 400kbit/s would be much faster than RS232 at 400kbit/s?

    I2C may be good for talking to some types of peripherial chips, but SPI is normally way better when having two processors talk with each other.

    But most serial transfer methods requires the user to define a protocol - what the transmitted data means. So for example for RS232 you need to specify this protcol before comparing with something else.
