I have a new project coming up that calls for a data acquisition board (wot I have to design) to deliver said data over ethernet at a minimum of 6.25Mbytes/second (not including packetisation/checksum/TCP/protocol overheads). I confess to some trepidation. Now, I'm an old hand at comms and microprocessory. However this is a couple of orders of bignitude larger, bandwidth-wise, than I'm ...

I have an embedded box that talks to a PC (a controller for an industrial device which is used to detect its state and also control it). I am using TCP (Ethernet). The way I understand, there are two ways to architect this: 1. Either the box is always the Client and the PC is always the Server, and then the only way the box will respond it when it is polled 2. Or both can act as both Client ...

Hi all, I am in the very early stages of writing a multi-threaded sockets application to enable me to communicate using TCP/IP to several (upto 255) embedded Ethernet controllers in VB.Net. Does anyone have any suggestions for where I could start to look for ideas for such an application? Many thanks, Jason.

Currently, I use AJAX to provide a near-realtime display of data for a device (basically data acquisition and some control). The box contains a 16-bit processor, TCP/IP stack, but no OS (I use timer interrupts the same way car companies use them in engine controllers). The user interface is a table of values read/set, some alarms when something is out of spec., and a few configuration ...

Hey y'all -- I'm throwing this post out on behalf of my poor beleagured programmer. We're starting to migrate over our new designs from using the Lantronix XPort for our network needs to an ARM9 with an onboard MAC (NXP LPC3250) and handling the network in software. The goals is going to be to keep things small; I'd love to manage to consistently keep code+data in the on-die RAM (256K) r...

Hello, I'm working with a 450-MHz SH-4 core. The architecture reminds me of the original Pentium in several ways, in that it is dual-pipeline with some restrictions on which types of instructions can be paired. When the system is receiving a 100-Mbps TCP stream (thus, at the same time also sending roughly 2 Mbps of ACKs) approximately 13-15% of the CPU is busy computing the internet chec...

Hi, I'm sure this is a trivial question, but since I'm just starting out, I'll ask anyway. I have a PIC18LF series MPU which I've succesfully mounted on a socket and demo board.

Can anyone recommend some ready to buy boards that are close to having these requirements: -Count 8 digital inputs (at upto 8KHz) -Periodically store counts to memory and reset the counts (say every 5 minutes) -Make that data available via FTP or some other easy and standard TCP/ IP protocal (must not be 'custom' PC side software). Due to small quantities I prefer just to by existing bo...

Hi all. I'm making a protocol for communication between a PC and a peripheral device. The protocol is expected to, at first, run on raw Ethernet but I am also supposed to not make any blunders that would make it impossible to later use the exact same protocol on things like IP and friends. Since I saw these kinds of things in many Internet protocols (DNS, DHCP, TCP options, off the t...

Hi all! I read a lot of discussions about Netburner vs. Rabbit.
