سلام عليكم
هذا مقتبس من شرح مكتبه RS-485 Library في مايكروسي ماذا يقصد كتابه بلون الاحمر واين استخدم هذه الثوابت
RS-485 Library
RS-485 is a multipoint communication which allows multiple devices to be connected to a single bus. The mikroC PRO for PIC provides a set of library routines for comfortable work with RS485 system using Master/Slave architecture. Master and Slave devices interchange packets of information. Each of these packets contains synchronization bytes, CRC byte, address byte and the data. Each Slave has unique address and receives only packets addressed to it. The Slave can never initiate communication.

It is the user’s responsibility to ensure that only one device transmits via 485 bus at a time.

The RS-485 routines require the UART module. Pins of UART need to be attached to RS-485 interface transceiver, such as LTC485 or similar (see schematic at the bottom of this page).

Library constants:
START byte value = 150
STOP byte value = 169
Address 50 is the broadcast address for all Slaves (packets containing address 50 will be received by all Slaves except the Slaves with addresses 150 and 169).

2- الا يوجد شرح لهذه مكتبه بالعربي او فيديو
3- هل توجد طريقه اخرى لكتابه الكود الاتصال RS485 دون حاجه لهذه المكتبه ام انها مهمه ويجب استخدامها عند التعامل مع RS-485 Library

مع الشكر والتقدير
