Legal Removal Request

Post: Hi, I would like to connect an Rpi (Master) to several esp32's (slaves) via RS485 communication protocol. Currently I use 2x RS485 Pi units to test with, where one is connected to Pi while the other is connected to esp32 (Esp32 Thing Plus, Pin 16 and Pin17). Echoing works fine from Master to slave unit. [pre][code]echo 1 > /dev/ttyAMA0[/code][/pre] My question is, do you have a software example that works with RS485 Pi which uses RS485 addressing? most examples / projects on the internet use MAX485 which has dedicated RE / DE pins but RS485 Pi controls automatically via TXD based on schematic, if i'm not mistaking? Right now i'm only connected to one slave and both ends fitted with120 Ohm resistors, normal UART communication works and i just need to sort out RS248 communication with dedicated slave addresses. To make it a little bit more clear i made a wiring diagram. [img]/docs/forumpost/beiqefo.jpg[/img] All inputs will be appriciated, Thanks in advance
