PIC programmer



because up


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?

  1. 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.

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,

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
