i have worked on lpc2388 ethernet. I have used RTL library and ethernet interface UDP protocol example file is tested, found ok.
I have replaced lpc2388FBD144 IC with lpc1788FBD144 but i am unable prove ethernet interface UDP protocol using KEIL examples.
Please look into this matter
How should someone 'look into this matter' without knowing your hardware and application? There are so many configuration options, such as clock tree configuration, external oscillator or external PHY.
We have one example project for a LPC1768 in the folder C:\Keil_v5\ARM\Boards\Keil\MCB1700\RL\TCPnet\LEDClientThis example handles a UDP protocol. You can compare your application with this example. Then you can evaluate some differences.
If you were using a LPC23xx device, I suspect you were using the Keil legacy Keil RL-ARM libraries. See: www.keil.com/.../rlarm_tn_tcpip_prot.htm
If so, from this page: developer.arm.com/.../Use-MDK-Version-4-Projects
...under "Legacy Pack Download" please download and install Arm "Cortex-M" (MDKCM525.EXE) into the C:\Keil_v5 folder.
Once you do that, you will find premade TCP examples in the folder: C:\Keil_v5\ARM\Boards\Keil\MCB1700\RL\TCPnet
==========If you want to use a modern version of the Keil middleware, There are CMSIS-PACK examples for the LPC1700
Open the Pack installer, C:\Keil_v5\uv4\PackInstaller.exe
- On the top left of the window, for "Search", type "LPC17" - the list below gets filtered. - Select the device (entry with a green icon) from the list below – on the right side of the dialog updates with Software Packs relevant to this device.- For the "Packs" tab, install the Keil:LPC1700_DFP pack (if necessary).- On the top right of the screen, select the yellow "Examples" tab.- On the "HTTP Server (MCB1700)" row, click the "copy" button - a dialog pops up.- Pick a directory, click both the check boxes, and press OK - a new Keil µVision session opens with the example.- Build the project, Connect a USB cable to the board and start the debugger.
