I just received a DT006 programming board form Dontronics fitted with a 2313-10. When I try to program the chip with a simply led routine I constantly get a verify error.

I can erase the chip, read oxff's, write the chip but on reading it back there are always a couple of bytes off from the original program. Chip Ident (from BASCOM software) also works fine.

Could the uC be defective or am I to look for something else?
Has anyone else out there had this kind of problem?

Thanks for any help I can get. It's not a fun way to get started in micros.

I emailed him a couple of days ago and haven't heard back.

I thought I'd see if anyone here had the same experience (not with Don but with the 2313). I guess my suspicion is whether any static could have damaged the chip. If the chip were damaged in some way, could it still erase, read and write but only have some errors at specific memory addresses?

Is it always the same bytes that are different, or is it just a few random ones?

Can't tell. I'll have to do a couple of tries and compare the results. It seems that it's the same location for the same program but different locations for a different program... puzzling.

Also, would a consistent memory location be an indication of a defective chip. I just got this stuff in and some extra 2313's but I don't have any static discharge equipment and don't want to chance damaging another one.

Any suggestions on a cheap way to stay static free until I order a wrist band?

Thanks for the help.

Thanks to all for help. I found out that my problem was a defective resonator. As soon as I wiggled it I got all kinds of LED activity. I replaced it with another and all works perfectly!

Now I'm smiling and ready to get in the microcontroller world!

Staying Static Free

1, Do not wear man made fibres
2, spray the carpet with water
3, Before touching a component touch something connected to ground. I was going to say discharge yourself but thought better of it.
4,Do not move!

"1, Do not wear man made fibres"

Or silk underwear, especially combined with wool:

*Work in your bathtub.

Preferably on high-voltage circuits with no current limiting.

I've decided on the bathtub with the high-voltage circuits. I thought I would tell my eleven year old son that this is the first step in learning to work with mircos.

Either that or invite my wife to join me for a jolt of a time!

Thanks,

BUT, if you are going to work in you bathtub better read the thread on M128:s and moisture...
