    Re: modbus communication in msp430

    which modbus ( RTU / ASCII / TCP ) you are implementing????????
    The hardware requirements are minimal - Any reasonable microcontroller with a serial interface, at least some RAM to hold the modbus frames should suffice.
    •A UART which support and interrupts and has at least an receiver buffer full and transmit buffer empty interrupt.
    •A timer capable of creating the t3.5 character timeout timer for Modbus RTU.

    FreeMODBUS - A free MODBUS ASCII/RTU and TCP implementation
