PIC18F67J60 questions

[dhouston]

I figure it will be worth the waiting and the seeing and the resolving of any conflicts. The Ethernet Module has its own set of interrupts (described in section 18.3 of the datasheet) which are independent of the ones used by the PIC so I'm hopeful there won't be conflicts. However, this is all obviously over my head else I wouldn't be waiting on Fred to work his magic or relying on your expertise with interrupts.

I got my Ethernet Mini Kit today.

A bit of searching turned up a commercial bootloader for the PIC18F97J60 family.

Looks like a start. (bootloader only)

Still hoping Mr. Eady comes up with something.

It should be in a forthcoming issue of Nuts & Volts.

I've assembled the Ethernet Mini kit and Brush Electronics has added a bootloader image for it to their Ethernet PIC package. There are still a couple of hardware related issues I need to solve. The board has 2x5 IDC headers for RS232 (non-standard pinout) and ICSP (differs from my EPIC and MEL USB programmer pinouts) - I'll need to design adaptors while waiting for Fred's drivers. I'm going to suggest to Fred that he include a schematic of an MEL adapter for the ICSP connector.

For anyone who wants to follow this route I recommend buying the kit with the PIC already mounted - I had to fix a couple of solder bridges on the SOIC-8W RS232 driver so am glad I didn't try mounting the TQFP-64 PIC. The other components are not too difficult, especially if you've done any previous SMD assembly. The most difficult part was in getting single 805 size components out of the itty-bitty (2-3mm wide) snips of tape. My left hand is partially paralyzed from a spinal cord injury and my eyes are in their late 60s so I usually feel that if I can manage this type of assembly, nearly anyone can.

I hope to use Fred's basic design as the foundation for a larger project. The MagJack he uses is difficult to source but PulseJack gave me a cross reference to their functionally equivalent (Pulse JP011821U) which is stocked by Mouser.

i'm planning to buy that one

as soon as it is available...

I'm kinda addict to their board now

Nice! But probably overkill for my needs.

I haven't looked at mikroBasic for more than a year. I gave up on them when they seemed to be experiencing interminable delays in supporting the ENC28J60. Now that I've taken a fresh look, they appear to have made great leaps since then - there's already support for the PIC18Fx7J60 chips, including an open source UDP bootloader, and they handle interrupts much better than does PBP. I don't think I'll wait for Fred's drivers.

I bought their EasyPIC4 board http://www.mikroe.com/en/tools/easypic4/. To be honest, I think it's quite impressive but nearly useless for anything other than educational purposes. There are no ZIF sockets. no any easy way to connect SOIC adapters, etc. nor can it readily do ICSP.

Just got the 67J60 to come online and I successfully received a frame.. Nothing but PICBASIC PRO mnemonics and one assembler instruction used.. a NOP.. Things should move along very quickly from here as all that's left is to do is enable the protocols and DHCP.. If things go as planned, you can read about my "adventures" in Nuts and Volts very soon via the Design Cycle column.. And, in a week or so you'll have some working code you can apply to your applications. I'm very impressed with the technical skills I've seen in this forum. I'm sure that some of my BASIC hacking in the MINI driver can and will be improved upon :-)

Have fun,
Fred

I'm getting really jealous of this mikroElekronika.
Anyone that ever though of making the perfect develmoent board to sell, might as well just forget about it. It's already been done.

Awesome,

Let us know which issue, so I can run down to the local electronics store and pick up a copy. (don't have a subscription)

Hi, Everybody
The first PIC18F67J60 Ethernet MINI article can be had in the July 2007 issue of Nuts and Volts. The article is geared towards the MINI hardware and the C driver. The C code that I'm translating to PBP can be downloaded from the Nuts and Volts site. You can also get the C source from the EDTP site. I'm basically taking the C code and translating it line by line to PBP.

If you are interested to see what PBP code I have right now, just let me know and I'll send it along to you. ([email protected])

The current PBP code fragment will bring the MINI online and look for an incoming packet. To use the code fragment you can use the arp -s command to stuff the PC arp cache with the MINI's IP and MAC addresses, which are laid out in the code. You must do this because the MINI can't answer an ARP request yet as it can't transmit yet. Once you have loaded up the MINI firmware and stuffed the PC's arp cache, you can ping the MINI and capture the incoming PING frame in debug mode. I am using MPLAB and an ICD2 to do the debugging. Once you capture a frame you can look at it in the file register debugger window. I have examples of an actual capture I can offer to you as well. Keep your eyes on Nuts and Volts as I will be describing the C-to-PBP port in detail there.

I've heard from many of you concerning the MINI and the code already and I'm always happy to provide to you whatever I can to help you be successful. I'm also open to suggestions and corrections to the code.

Fred -
You guys are just too cool! Thankyou for all the work you guys have done over at EDTP, and taking the time to share with everyone. I just read Peter's article in Design Cycle. Very nice work.
