LAUNCHXL2-570LC43: Assign Static ip Address for TMS570LC43x Launchpad

Hello Advaith,

For LWIP demo, it can use an static IP address and can obtain an IP address from a DHCP.

Hi QJ

I was able to get the ip address of the router through the LWIP demo. Can you please explain how to assign static ip address to the launchPad in the LWIP demo programming ?

Best Regards: Advaith

You need to define the IP address before calling lwipInit(): for example

uint8 ip_addr[4] = { 192, 168, 2, 44 };
uint8 netmask[4] = { 255, 255, 255, 0 };
uint8 gateway[4] = { 192, 168, 2, 254 };

ipAddr = lwIPInit(0, macAddress,*((uint32_t *)ip_addr),*((uint32_t *)netmask),*((uint32_t *)gateway), IPADDR_USE_STATIC);

Will this step allow me to assign static ip address for Launchpad?

This is just an example of how to assign IP address to ip_addr[] etc. You need to find an available IP address for your setup.

Thank you for the reply

Can you please reveal the type of communication occurred when ethernet cable is connected to the Launchpad and router

Please refer to this application note:

Hello QJ

 Is it possible to detect the ip address automatically?

In lwip example we need to provide the ip address of the device which is to be connected.

My requirement is to detect the ip address automatically  when an unknown device is connected. Is it possible? Are there any codes for that?

Hello Advaith,

I don't know if LWIP has this feature or not. 

Hello Q J

Thank you for the reply.

Can you please reveal how to implement a application layer program to LAUNCHXL2-570LC43?Please....

Kind regards: Advaith

Hello Advaith,

Our LWIP demo does include the example of the application layer:

1. Device initialization

2. Selftest:Pbist, CPU selftest, flash ECC, RAM ECC

3. Call the LWIP APIs
