'Advise reg. Programmer'

Hello all

I am new on the list, and new to the PIC- We are soon starting a project
using the PIC16c93 and therefore I am looking for some advice regarding :

Purchase of a PIC programmer; We are currently looking at the PRO-MATE II
from Microchip - are there any third-party programmers we should consider
instead ? prisewise cheaper is better however support for the full serie of
PIC's is essential.

I have been looking at the Microchip homepage and seen references to the
windows based development environment MPLAB ? is this for free or ??

Reg the 16c93 with build in LCD driver ; Is the driver any good ? and Can we
drive a 20x4 char LCD on it ? I have tried to look in the datasheets however
for me some parts are a bit cryptic and I am therfore in the dark here.



Any help would be very much appreciated

TIA

   Peter:

   If you need the programmer only for relatively low-volume
   programming during development, Microchip's Picstart Plus is
   probably a better choice... It's a LOT cheaper than the Pro
   Mate, and it programs all the PICs.

   It's free; you can download it from Microchip's web page.

   The 16C93 drives LCD segments DIRECTLY; it's intended for use
   with raw LCD displays like the sort you'd see on a digital
   watch.

   The 20x4 character-based LCD displays contain their own driver
   chips (usually made by Hitachi); they're controlled by sending
   commands and data over a parallel bus, so all PICs are equally
   suited to driving them... The LCD-driver hardware in the 16C9x
   doesn't provide any advantage.

Peter,

Have a look at the EMP-20 from Needham Electronics. It can program most
of the Microchip devices as well as micro's and eproms from alot of
manufacturers. I've had one here for years and it works great.

PRO-Mate is quite expensive - you can probably find a programmer to do
PICS AND heaps of other devices for the same price.

I presume it works, although the data sheet isn't too clear on how low
you can get the power consumption.
> and Can we drive a 20x4 char LCD on it ?
Not directly - it wont handle the high multiplex rates to drive a 20x4
char matrix glass direct. If you're talking about a 20 x 4 offf-the
shelf LCD module, all you need is 7 bits of normal I/O as these
modules have built in display controller and RAM, so almost any PIC
will do.

I second the vote for the Needham's EMP-20. If you were considering the
ProMate, the $449 for an EMP-20 isn't bad. It also qualifies as a
"production" programmer, since it verifies at the limits of supply
voltages. It will always take a few weeks for support of new chips, but
eventually they are all covered. Parallel port. Digi-Key throws in the PIC
personality module free(though you'll still need one or two others to
cover the whole line, at $25 each)

The Picstart Plus is a good choice for an inexpensive, development
quality, pics-only, windows-only, serial port programmer. I think the $149
price is still valid at Digi-Key.

I have never had trouble with either of them.
