Hello newsgroupers! I have an embedded ( 32bit ) processor which shall have an IP connection to the outer world. I looked at a few IP-Stacks like CMX / FUSION / IOSOFT and OPENTCP. Can anyone tell me his experience he made with the stacks? A link to an comparison report? Any help is appreciated. Kind regards Peter

Does it even matter? I've been doing the smaller micros (PIC, 8052, etc) in assembler for quite a while now, and I'd like to tinker with some ARM type stuff using C (gcc will be fine). I want to be able to use TCP/IP on the board. Looks like Olimex makes some pretty decent looking dev boards for cheap, but I don't know if I should lean towards the LPC line or the SAM7. What say ye? ...

Hi, Could anyone lend some light into which protocol or technique is used to actually send I/O from a legacy serial port device onto a TCP/IP network? I see there are many products out there, but none of the product sites describe the actual protocol used on the IP network side. An RFC search also came up with nothing, though I could have missed it as well... I know that on the client s...

Can somebody help? How is TCP/IP stack usually designed in OSes if different physical drivers with different physical maximal size of frames need to be transferred? Does IP stack do any interrogation during startup procedure to investigate how much is maximal length of the frame of particular device - e.g. Ethernet, FDDI, WiFi? Thanks.

We have a product which uses a heavily modified, somewhat custom, TCP/ IP stack. One of our university customers is reporting problems, which appears to be caused by some sort of traffic on their network. I think it might be some sort of exploit scanner...

Does anybody know of a cmos based camer that has an intergrated microcontroler which can be programed to process images, background subtraction - point tracking and then stream custom data across tcp/ip? It just seems so wrong to be using usb cameras, I'm streaming 4 into my computer at the moment and the bandwidth on my usb2 is already critical - what i want is a cloud of customisable visi...

Hi. I'm looking for a 32-bit kernel with preemptive multitasking (realtime is not required). It should be simple & lightweight, and be written in hardware independant C (with full sourcecode). Considering that my project requires a TCP/IP stack, I would prefer a kernel for which such support modules have already been ported. This is for replacing an 8-bit system to PowerPC. While I do...

Hi all, I want to be able to use Ethernet in my projects but I'm so overwhelmed by its complexity that I don't know where to go. I've read and watch most of the information at microchip.com. I'm aware of the new PICs that have a MAC built-in and the ENC28J60. I'm also aware of the TCP/IP stack and the rest of the ... stuff (DHCP, ARP, etc.). The reason I say "I'm aware" is because I d...

Hi All, Just wondering if anyone using the CSB337 has done any ethernet benchmarks? Preferrably through a TCP/IP stack. We are using uCOS-II but Linux (or any other OS) would be fine.

I have a couple of interrupt drivers to write that have ...
