Let’s look at two structs which contain the same amount of data, but have different sizes in memory: If you do get the stack working, if you don’t mind, we would appreciate it if you would post a copy of it here on the forums. Direction of the Reset pin must be defined before using this function. Is this for posts prepared to work? This is DHCP module routine.

Whats going on you might ask? Otherwise DHCP will override these settings. Without ARP no other device in your network will be able to send packets to yours unless you bypass all protocols and set the MAC address manually in your packets.

In principle the first bytes in packets are part of the headers, and via the headers you should be able to determine what this packet really enc228j60, look here from bottom to top The http request headers can be found a couple of levels deeper in the stack; but you will have to traverse all layers from the figure in the above post.

I am only an observer to this thread – I think these answers should be awarded, never seen this much attention for problem up until now. Then you need to figure out what type of packet it is. My solution was to simply only use char or short types within the predefined structures I was modifying, and then use a macro to access the memory as needed.


Additionaly, all filters, except CRCenabled with ecn28j60 routine will work in OR mode, which means that packet will be received if any of the enabled filters accepts it. Hi, Nice work… Can u upload err. Is this a personal project or for work? It is a cooperation of 8 CoIDE projects, each responsible for a piece in my software.

I can’t even begin to tell you the trouble this has saved me in the past. Well since you are doing motor control the F is an excellent choice.

Every struct that is used to read or write to the pbuf payload field must be modified to use the tShort type that I defined in my last message. Hope it can help.

The lower byte of each 16 bit word contains the same data that would have been there in the buffer on the original architecture, but the upper byte is all 0s.

Jim, I just took a look at the sources and I see what you mean. For example, the npp and packet length are way too big. Could you make an example for PING. My version of the hardware driver can be found here: If this is the case, I believe you are correct in your frustration.


The hardware abstraction layer requires at least 3 methods: The incoming packets will be processed normaly during this time.

Then check the NTP modules ntp. Moving to use the real SPI peripheral shouldn’t be too difficult.

They have an onboard ethernet controller, lwIP is already ported and runs on the core, not to mention you get USB and several other useful peripherals. The way the buffers and structs are passed around is almost exactly the same as the other stack I’ve been working on.

I made 2 separate regulators switching ones for both 5V and 3V3 lines.

Once I initialized the RX buffer before everything else, some of the problem went away. This is wasteful of memory, but for now let just get something working first. Trademarks Enc28h60 Policy Terms of Use. Keep watching the TI site specifically the C area, I think you’ll find we’ve got you covered.
