PIC programmer

Hello,
I need help to acquire a programmer of PICs that works perfectly.
I have Warp-13 NewFound Electronic and another of the manufacturer Olimex,
neither one assist my demand. I am wanting to program 16F628, 16F874 and
16877.
I would like to know where I can buy a programmer to be reliable, because up
to now I spent money without having a satisfactory result, only a mistake.

TIA
Fernando Carvalho

Hi, Fernando. As to your Olimex programmer (you don't mention which
one) you might want to try the US user group for the programmers:

Browse thru the old posts, and you might find your problem solved.
Also look at the tutorials and the FAQs on that site.

I'll bet you've already spent all the money you need to program PICs.
But without any specific information, I'd just suggest that you first
look to your cables. The contacts do wear out. Borrow a new one and
try it. Also try to use a test bed computer with a minimal system and
no other concurrent programs. I've seen "development beds" which have
so many programs running, they hang themselves up whenever anyone
presses a key or clicks the mouse. It's best to reformat and reload
from scratch. Make sure the BIOS settings for the PC ports are
correct. You don't need the fastest computer, but you sure need the
most reliable. Look also at the port pins on the PC. If some are
wobbly, that might cause problems.

Good luck
Chris

 

Jameco Electronics has one for about $60 American. I have not tried it,
but have found that they are very good about products they have sold me
over the last 25 years or so.

OK, a few questions:

1. ICSP? If so, LVSP or HVSP? In any event, anything else hanging on
MCLR, clock, or data programming lines?

2. Vcc = 5V or something else?

#2 is very important - officially a programmer is supposed to verify at
min and max operating Vcc. Few (no?) hobby programmers verify at other
than 5V.

#1 is moderately important for ICSP. Simple parallel ports drivers or
even most buffers won't have enough drive current if there's other
loads on the pins.

Hi Fernando,

I'm using Picstart Plus (that I got from Digikey), and have had very good
luck with it. It will program the three Pic chips that you mentioned. It
uses the serial port for communications. I am very happy with it.

I sell some rpogrammers, but if you just want to program those types
but can not succeed using the programmers you mention IMHO you are
doing somthing seriously wrong. Get help, from one of the forums,
maybe www.piclist.com can help.
