TIDA-00203: How to Enbale DHCP

Part Number: TIDA-00203

i have CAN to Ethernet demo board. The board is getting ping with 169.254.254.255 successfully.

i have source code of CAN to Ethernet  which is download from TI web site.  Now ,what do i  make change in downloaded source  code to communicate with  TIDA-00203 Board through static ip other than Default ip (169.254.254.255) , and also how can i enable DHCP for this board.   

  • Hello bhupendra,

    This demo code was only built to work for static IP functionality and showing the TIDA-00203 TI design is working.

    To better understand how the lwip stack works please look at the documentation SW-TM4C-UTILS-UG-2.0.1.11577.pdf and SW-TM4C-UTILS-UG-2.0.1.11577.pdf, which can be found in the folder:

    C:\ti\TivaWare_C_Series-2.0.1.11577\docs

    As a Ethernet example software with detailed explanation see the example project "enet_lwip".

    This example shows how to setup the lwip stack in different configuration modes according to the documentation from the pdfs mentioned before, this example can be found in the folder:

    C:\ti\TivaWare_C_Series-2.0.1.11577\examples\boards\dk-tm4c129x

  • Hello ,

    How can i used UDP protocol in the source code which i have downloaded from TI website.

    could you please send me any sample source code which gives data of can to Ethernet in UDP protocol .

  • There is no direct example showing this data transfer.

    The following thread explaining udp data transfer with code example using the lwip stack:

    https://e2e.ti.com/support/microcontrollers/other/f/908/t/723207

    From here you need to connect the CAN and the UDP packet payload.
