Hi @Kvpkumar ,
Thank you so much for your interest in our products and for using our community.
I am sorry to inform you that the LPC5516 does not support DS402.
Apparently DS402 is supported through Real-Time Edge Software, in this link you can find the supported platforms and more documentation about it.
Hope it helps you. Please let me know if you have more questions about it.
Have a nice day!
