Thanks for all the responses to my previous question.
I have a circuit that basically has 5 inputs, which have to
be periodically polled and the on/off nature recorded to
a serial eeprom.
Currently, I am using a 16F628A, but I am wondering
whether it would be possible to downgrade to an 8 pin
device.
I use 2 lines to connect to the serial eeprom.
Since 5 + 2 is greater than the # of I/O lines on an 8 pin
device, is it easy to make one pin bidirectional? I am
thinking that one pin could do double duty, but since
all I did was cut and paste the code to interface to the
serial eeprom from a website, I'm not quie sure how to do it
exactly.
Thank you.
