PIC18F67J60 questions

[edtp]

Looks like a start. (bootloader only)

Still hoping Mr. Eady comes up with something.
<br>

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 planning to buy that one

as soon as it is available...

I'm kinda addict to their board now

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.

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.

Anyone planning to use the 18F67J60 family of chips needs to study the datasheet as there are several things that are different from the PICs I've used before.

There are no clamping diodes on the inputs so you need to pay attention to max limits which are not the same for all pins.

Some pins sink/source 25mA, others only 8mA, still others only 2mA.

It's a 3.3V device and while some pins are 5V tolerant, others are not. Any other chips used in a design need to operate at 3.3V or may need level translation.

While searching for something else I came across a mikroBasic project for a UDP bootloader (using the ENC28J60) and 18F PICs.

• http://www.mikroe.com/en/projects/

It seems to be entirely in Basic so it should be possible to convert to PBP although I have no idea, as yet, what changes will be required for the 18Fx7J60 chips.

Hi, Everyone
I'm behind schedule. However, I will be posting new Ethernet MINI code this weekend on the EDTP Electronics, Inc. web site (www.edtp.com)..
The new code adds DHCP support and fixes some bugs I found..
I plan to port the TCP portion soon unless one of you beats me to it..
So far we have UDP, PING (ICMP), ARP and DHCP.. All that's left is TCP..

You can read about my exploits in this month's Nut and Volts..

Have fun,
Fred
