Hello, I am using a Keil MCB2300 evaluation board with LPC2378 and Keil's =B5Vision3 IDE (evaluation). I want to send blocks of data via TCP/IP to another computer and vice versa receive data from that other computer. Just this, nothing else (regarding ethernet). Now, I know that the ethernet subject is a very complex one. I am looking for a simple solution that doesn't force me to dive...

Hi, I'm looking at the LPC23xx datasheet , but I'm not really sure if there's an hardware way to calculate CRC for Ethernet RX/TX frame(like the one on the microchip ENC28J60 controller even if it doesn't work :) ?? Kind regards.

hi, everyone, Is there a kind of MCU that includes at least one on-chip CAN transceiver(like LPC11c24), plus the following features? 32-bit ARM7 architecture, 128K flash, 16k SRAM, two SPI interfaces, RTC, UART, IAP, watchdog. It would be best if it contains one ethernet port, and be able to run uclinux. ------------------------------------

Hello everyone, Would an LPC2000 device be fast enough to act as a voip interface (i.e. ethernet in one end, one channel of audio in/out at the other)? All the VOIP software stacks I can find seem to based on Linux so I presume it would have to run uclinux. It doesn't have much other work to do so can be pretty much dedicated to this task. If anybody has had any experiences in this area it...

Hi, I'm regarding a project for a HMI + communications. I do not want to use BGA components and keep all on a two layer board, so the only single chip solution I found is the all-in-one LPC2478. Initial idea for GUI is uCLinux + Qt4, but can this ARM7 handle such a thing? I'm talking about QVGA or 480x272 screens and controlling ethernet, USB and RS232/RS485. Some advice?? Thanks, Oscar ...

Hi everyone, I'm currently having problems with the MAC_MAC1 register on a board similar to the MCB2300. I'm trying to run the easyweb keil example but it crashes when MAC_MAC1 = MAC1_PASS_ALL; I'm debbugin with the ulink2 but when I run that line it crashes with error "Could not stop arm device! Please check the JTAG cable". Has anyone solved this problem? Thanks in adv...

At last! An ARM controller with all of the peripherals I need (with the possible exception of CAN). For the last 18 months I have been in search of the holy grail when it comes to ARM + peripherals... and it seems that NXP have finally found it for me. My research has shown that (previously) ARM9 processors by the likes of NXP, Cirrus Logic and Atmel all had one key component missing - suc...

Hello, Every network equipment has a unique MAC address for it. Does the Wiznet NM7010A ethernet controller also have a MAC address of its own. If no what should the address be, as the MAC register needs to be set. Regards, Vineet. --------------------------------- Yahoo! Photos Got holiday prints? See all the ways to get quality

Hi all. I have a problem with lpc2478 and lwip 1.3.0. I can not see ping replies after requests, but scanner like ethreal or wireshark gets all replies OK. Host always retransmits tcp packets while telnet session but lwip replies only some of them with great delay... I use board form embedded artists and ethernet driver from micrium.

Hi I'm about to start develop a new system using the brand new LPC2478 (LPC2468 with a LCD controller) I have a dev board from Embedded Artist So before I use $$$ on development tool, j-tag etc. I just whant to ask some Q here. My needs are as following: - Good supply of samples for the interfaces (USB Host, Ethernet, UART, SPI, LCD etc) Prefered is that the development tool c...

Hi all! I am trying to use the SRAM on LPC1768. I modified the LD script and put the attribute to the variables that I want to put in to it. Also I enabled the power to the SRAM, but still it is not working. Am I doing something wrong? LD script (the important sections): *************************** ...

hello, I need to interface someLPC with Lantronix Xport (UART to ethernet gateway in an single RJ45 connector). The max baudrate for the Xport is 900000kbaud/s. Can I obtain it with LPC ??(I don't find the max in the user manual :( ) thanks in advance.

Hello Geeks ! I am trying to interface LPC2368 ethernet with the National's PHY DP83848. The selected mode is MII. But the PHY is sending 0xFF whenever i try to read the status register and for ID query, ID1 it gives 00 and ID2 it gives 0xFF. So.....its easy to say that its not working. Any ideas ? The connections on each pin are as follows : 1> Pin 1,5,6,8,9,10,11,12,20,21,38,42,45,46 ---

Hi, Actually we're developping a board with the lpc2378. We're using an RTOS with ethernet,can , sd card,serial port, and all of thet eat a lot of memory ... I have just saw the LPC2388 with 32+8 KB more . It's seems pin to pin compatible with the lpc2378 but can I expect the same bugs than the lpc2378 (for the peripherals of lpc2378, so excludinf dac and otg) ? I really don't know if i...

Hi group, I have a demo application here doing network IO over the ethernet mac that works like a charm with 10Mbit speed. However, if I hook the board up to 100Mbit, the best thing I can get to is a very much delayed processing of 100Mbit frames. It seems like the MAC gets the frames with a delay of several seconds only from the PHY. The funny thing is no frames are lost! They just a...

I have been having intermittent problems with an LPC2368 design in that the processor sometimes fails to start up when power is applied. There is an ethernet MAC on the same power plane that does start up (indicated by speed & activity LEDs), but on the 2368 my code does not run, and attempting to connect via JTAG fails. I have observed this on several different units, it is not particular
