Have anyone of you guys ever using a HC11 with an ethernet card? I'm doing my project, in which I intended to connect the microcontroller to my PC using an ethernet interface. I search the web and found such a card made by edtp(http://www.edtp.com) called packet whacker. Does anyone ever used that card? Any comments or suggestions are appreciated. I'm really kind of need information for my project. Thanks.

I managed to get a read-and-write-a-udp-datagram back and forth from the pc program working. Our company has a board we built with an hc11f1 and a 32k ram and a 32k rom and a cs8900a ethernet chip. I think Tech Arts has a neweer eth card for thei hc12 boards... maybe it will work with their hc11 cards too.... [Non-text portions of this message have been removed]

So I don't want to waste money buying an eth board with a chip on it. Your company's solution is interesting to me. Does it comply to hc11e9 chip? Is there any detailed manual or instructions included in your product package? If so, could I have a look at them beforehand?

I'm really kind of need information for my project. I haven't used the card, but I looked at the site and see that they are using the Realtek RTL8019AS. We had a bad experience with this chip on a project a few years ago. Basically, its input sensitivity is nowhere close to the Ethernet standard. The heartbeat detector says "no heartbeat" if there is even 4 or 5 dB of loss from the hub/switch. The standard specifies a frequency-dependent loss model of roughly 11 or 12 dB. We observed that the chip seemed to work fine with short cables (read: in the lab) However, on customer sites and especially with certain brands of hubs - and even with short cables - the heartbeat detector would say "no link". This switched the chip over to it's coax input (the chip supports both UTP and coax for NE2000 cards). The effect was that our box would go blind for a few seconds or a few minutes at random intervals. Took most of a summer to figure that puppy out. Realtek eventually admitted that the chip didn't meet specs, and we switched parts (actually, ISA Ethernet cards back then) Best regards, John Hartman NoICE Debugging Tools http://www.noicedebugger.com [Non-text portions of this message have been removed]

Hi Venkata, > I used Embedded 10-BaseT Ethernet card from > http://www.embeddedether.net/ > You may want to look at my project > http://mason.gmu.edu/~svenkata/m68hc11/ Very interesting. Did you roll your own UDP/IP stack, or did you port a PL stack such as lwIP?

Forum, I used the Seiko S-7600A chip for internet access. This is a simple SPI device to interface and the code is not 'to' difficult.

Hi, I've made a 68HC11 board (E1 version) with an IEEE 10BaseT interface (CS8900) these are few years ago. It works with uC/OS II and with help of students we have developped a restricted TCP/IP stack (just TCP incoming call, UDP, ARP, ICMP). All is available here (HW and SW and report): http://www.enseirb.fr/~kadionik/68hc11/carteether_enserb/carte_68hc11_ether.html See this too: http://www.enseirb.fr/~kadionik/68hc11/68hc11.html May this help you; Pat. wrote: >Forum, >I used the Seiko S-7600A chip for internet access.

Yes. I wrote my own UDP/IP stack. Very simple and lean one. Initially, I looked at a viable simple free UDP/IP to port (like, http://ucip.sourceforge.net/) but, with all "microC-OS-II + ethernet driver + UDP/IP stack" is not fitting into 32KB of mem (even after, removing some unwanted code from kernel, like message passing code, stack sizes etc) Venkata.

I too second John's opinion about RTL8019AS. Its a complicated chip with a 30+ page documentation. we also interfaced the 68HC11 with the NIC card (packet whacker) from www.edtp.com but i ported the code written for CS8900 for 68HC11. we implemented telnet and ping program. CS8900 has a good support with all the required documentation. you also get a board from www.edtp.com which has cs8900. -anand --- "John Hartman (NoICE)" <> wrote: --------------------------------- >Have anyone of you guys ever using a HC11 with an ethernet card?
