Code writing/comms problem with PIC programmer 1

[haggisbasher]

Hi all,

I have just purchased a pic programmer tutorial kit from Velleman. It is called K8084 PIC programmer. it has a PCB that you have to populate and programming software on disc. I'm using an Advent7340DVD laptop.

Here's what I've done and the problem i'm having now:

(1)Populated circuit
(2)Powered up OK
(3)Installed and unzipped software to a desktop shortcut (file characters have to be under 63 to assemble code)
(4)followed instructions for compiling (successful)demo.HEX file created (using MPASMWIN.EXE)

Problem comes when I try to write code with PCB connected via 9 way serial port with chip in IC plug (pIC 16F627).

Using PICPROG2.EXE and following instructions for setting software, when 'write' is selected a warning comes up saying 'K8084 not found at COM1'? This is where I am unsure what to do next. The com port1 in device manger is on address 03F8-03FF and IRQ4 and on generic bus.

I have checked base I/O address in F2 set-up, it is 3F8 IRQ4 on 'user'.

I have no idea what to do from here. The PROGPIC2 software has a selection for COM1-COM8, none of the others (2-8) work. Error message COM-INIT-ERROR comes up if any of these others are selected.

I have also used a tower PC and it does exactly the same i.e. 'K8084 not found at COM1'.

The instructions say that any other device shouldn't be using IRQ3 or 4. How do I find that out?

Hope someone can help..?


Regards


Andrew

Haggisbasher, Guys, lets keep this in motors where it was mistakenly started.

Sorry for the run-around Haggisbasher. [flush]

Furthermore Haggisbasher I would post this type question in either ELECTRICAL/ELECTRONIC ENGINEERING or CIRCUIT ENGINEERING not PROGRAMMABLE LOGIC CONTROLLERS.

Haggisbashe; Someone got torqued and blew off your original post. Hope you read it all first.

With respect to the Hyper Terminal, instead go to my site and get MTTTY.

It's a great little Terminal program and has none of the baggage present with HT.

On the left there is a "DOWNLOAD" box. Hit that, then on the new screen download MTTTY. It is pretty self explanatory and a definite tool to toss into your bag of goodies.

I like the MTTTY. Good to have in the computer. This one I understand - not always the case with other terminal emulators.

Glad you can use it skogs.

Yeah that was a MSFT C compiler demo program. I hacked it a bit. I use it all the time for stuff. If you need it to do something just check the boxes until it does what you want..

Hello itsmoked

I suggested he post in this forum and did not mean to lead him in the wrong direction I am looking forward to comments about this post as I have a similar problem w/Allen
Bradley hand shaking with my 1747PIC and com 1 I will keep an eye on further comments.

Also I'm not requesting to address my issue as I do not want to hijack this valuable post.

Thanks for MITTY it looks interesting.

Thanks, Chuck

Howdy machmech;

Glad you too can find some use for that tool.

Haggisbasher seems to have dropped off the radar so what's your problem? What is a "1747PIC"???

I'm sorry for the slang, I was referring to the 1747 - pic interface module Allen/Bradley uses to communicate from an rs232 device (modem) to an SLC 500 processor.

I have a rack at home and it is a Father/Son project so I am not under the gun to get it going! I have gathered some information and need to check some things out, but until I have exhausted all my efforts and were not having fun anymore..

Then I'll bring it to the big court to see what you guy's can advise.

Thanks, Chuck

machmech; use MTTTY and a cable. Jumper the cable to get echoing back working using loopback.

Then hook it up to your card and try catching output and cramming chars back in.
