e128 irda to palm/pocket pc

Started by eeetee2000 April 1, 2005

hi:

i'm using the e128 processor that supports irda. i can take two of
these devices and communicate back and forth with a standard i/r
transceiver on each. scoping the signals (tx and rx) indicates that
it is indeed 3/16 pulse time as per spec. so i'm assuming the
hardware and code are working as they should.

i need to be able to communicate with a pocket pc, so i purchased a
communications utility called vxHpc that features "capture text"
and "send text" routines. i can't seem to get the communications
between the pocket pc and the e128 established. my task is quite
elementary, i just need to send to (and receive from) text between
these two devices. has anyone been down this road?

thanks in advance! regards,

ed taylor

I haven't used IRDA, so I can't offer specific advice, but in my
experience, if you only know that the pulse timing is OK, you don't know
enough to assume anything. Can you try sending the same data string on the
E128 and the Pocket PC, capture both strings on the scope, print the
results, and compare the two? I am assuming that you have a storage scope
for this, if not, you're pretty much up the creek.

hi gary:

thanks for the reply!

great idea .. missed it entirely. i'll monitor the data from the
pocket pc at the receiver of the board. too simple, thanks! regards,

This is the 1st time I see your message, so it's good that you sent it again.
I want to work with the IrDA, so I learnt a little the issue, but I did not communicate
with PC yet.
I can send you several specifications that might help you
If you need it please write to my mailbox, and I will send it to you.
