Hello
Sorry for
the spam but I have a very simple question that I haven’t been able to find an
answer to:
I need to
read in some data to a computer from an ADC I already have.
The communication
is a parallel connection and should work as follows:
The ADC
puts the binary number on the data lines when it is ready it activates the
ready line.
When the computer
sees the ready line it should read the data lines, transfer it to a buffer and
then activate an Acknowledge line.
After which
the ready and Acknowledge lines are deactivated.
This should
then be repeated and possibly quite fast so I would like it to be done without
direct interaction of the control program and only by reading the buffer.
When I read
about different IO cards I would like to call this handshake is this correct or
does it mean something else?
If a card
is specified as supporting handshake does it then automatically support the
buffer part or should I look specifically for this too?
Thank you
for your help
