<x-flowed>I am a newby to PIC's,the last processor I used was the 6502. I have a
project which I need a 10 bit A/D and some number crunching. I have
tentatively picked the 16F873/4/6/7 as it has flash program memory.
1. Do I need a programmer or can I just program it in circuit?

2. I am tying on a ISD Voice Chip onto it and I notice some come with a
SPI/Microwire interface. What is this and is it messy to program?

3. I have downloaded MPlab. What else do I need to program? I would prefer
to program in Basic rather than assembler, is there a shareware or
inexpensive compiler on the net.

I would appreciate any help with the above. Thank you in advance

You need a programmer to program it in circuit at least for the first time
You can write your own downloader and then get the chip to self program.
I have this idea working very well over a RS232 link.

Hi Geoff,
have a look at:
http://www.dontronics.com/pickaxe.html
http://www.dontronics.com/auto.html
http://www.dontronics.com/dt106.html
http://www.dontronics.com/p16pro.html
http://www.dontronics.com/piclinks.html
http://www.dontronics.com/picbasic.html

This will give you a bit of a run around with the 877 and several
basics.
There are some interesting basic compilers around.
I am just adding another freeware one that I was informed of today on
this list, to my piclinks page now.

<x-flowed>I have pic basic pro if you are interested.  You can get a lite version
from http://www.melabs.com for the 16f84 only... also, i have the PDF file that is
the instruction book.. this basic is extremely compatible with parallax's
pbasic.

You might want to look at the PicBasic Pro compiler (ME Labs). You can use
it from within MPLab. Get Microchip's PicStart Plus programmer to go with
it. The code samples that come with the compiler include serial routines
for I2C and A/D on the 16C7XX. Not sure whether this will be completely
adequate for your application but the compiler does also accept inline
assembly code.
