rs 485 library and help!!

hi

I am using servo motors with built in controllers and have to communicate with my controller via rs485 ...
i was wondering is it possible to use the rs 485 library in mikro c compilers with slaves whose program is compiled with different compilers .

another thing is that does any one know where i can get microchip's library for rs485

Thanks!

Hi,
As far as your program is concerned RS485 does not matter, it is only a hardware driver to drive long lines, and it can be connected to RS232 serial TX/RX pins, the program will not even know about it. Read more about RS485 from www.maxim-ic.com .

check the following link https://jap.hu/electronic/pbus.html

RS485 is simply a 2-wire balanced line (electrically) system of transmitting RS232 UART protocol. It also includes addressing bytes to get the attention of other specific microcontrollers "listening" to the wires. Each microcontroller connected to the wires requires a RS485 IC connected to its UART RX/TX pins and 1 or 2 control lines for either Writing or "Listening"/Reading what's on the lines.

It doesn't matter what compiler programmed the other controllers. You only need to know how to get their attention (through RS232 communication) and talk to them with your microcontroller. That communication information you can get from the manufacturer of the servo controller. How to directly control the writing and reading the lines is found in the 485 IC manufacturer's datasheet, including how to physically make the connection.

Here is an example of someone who sells such 485 servo controllers and provides that information about their system:
