[ajay dange]

Hello, i am developing an application in which i want to use raspberry pi as a modbus server to which number of devices will be connected.

I have compiled libmodbus on pi & able to run all the programs under \test  folder. now what should i do now if i want to connect devices to raspberry pi GPIO pins and controll them using modbus.
a modbus client will be a program runnning on pc.

What changes do i need to make to source of server.please provide some guidelines.

Hello,

You can't directly use the modbus library to drive the gpio's because Raspberry pi uses either python library or wiringPi/pigpio libraries to control teh GPIOs.

You need to write your code inside the opensource modbus library.
