Epistle to the Piclist,

Naturally, this seems like a great opportunity for me to get my first
embedded project contract.  I am confident that I should have no problem in
writing the software for this, since I have already done allot of coding
(with far greater complexity) on the 16f84.  However, it seems that this
will require use of a PIC with ADC capabilities.  What is the cheapest PIC
that has this capability?  Or, should it be done some other way?  From the
stated requirements, does it sound like he wants hardware design also?  What
would be a fair way (price?) to charge for just the software.  Come on guys,
give me some input.  Surely everyone here had to have their first time.  I
sent him an e-mail, but he may not even consider me.  Nonetheless, I would
still like input (flames?) from everyone.  Please share personal thoughts on
getting your first embedded contract.  I have done allot of programming, but
never for contract.  I would greatly appreciate any input I can get.  Thanks
and TTYL

low

"B")

a

start
