Having Serin Serout problems

[Elusiveinc]

Demon: with just a slave and a master. It still only works most of the time not all. Thinking about adding a pull up resister to connecting lines. Kind of been wondering if the internal pull ups are not enough to keep logic high while the serin processor is waiting for serout processor.

mackracket: The "a" gets reset later in the program. Each micro only makes the loop one time. a cycle of serin and serout. If my logic is correct it won't matter in this section.


This is my first time playing with serin and serout. at 9600 baud on a 8mhz chip. Should be extremely reliable right?
