Im working on a project i made most of them but i have problem with communication. Lets say i have wemos d1 as master and 2 arduino uno as slave. From master i have to send 2 integers (integer1=5 and integer2=6). i need to send integer 1 to slave 1 and integer 2 to slave 2.
Do you have example for this ?
This is the rs485 module i use. it just have rxd and txd. Can you write a example code for this rs485 communication ?
I'm really new to coding arduino and couldnt find any examples for this module to transfer different data to different slaves.
