Title: conflicted define in modbus.c
Post by: Kiger on June 01, 2017, 08:45:49 AM

Dear Mark @mark,

The  AUTO_RS485_RTS_SUPPORT define   was conflicted.

in line 910#  of modbus.c

        #if !defined AUTO_RS485_RTS_SUPPORT && (!defined _LPC23XX && !defined _LPC17XX) // {V1.19}
        fnConfigRTS_delay(ucMODBUSport, &tInterfaceParameters);
        #endif

the function "fnConfigRTS_delay" was invoked when AUTO_RS485_RTS_SUPPORT undefined.

But in line 358#  1687# the function was declared and implemented when the "AUTO_RS485_RTS_SUPPORT " was defined.

line 358#
    #if defined MODBUS_RS485_RTS_SUPPORT
    static void fnConfigRTS_delay(unsigned char ucMODBUSport, TTYTABLE *InterfaceParameters);
    #endif

Hi

I think that you are using an older version of the Modbus package.
From V1.27 it has the following:

        #if !defined AUTO_RS485_RTS_SUPPORT && (!defined _LPC23XX && !defined _LPC17XX && !defined KINETIS_KE && !defined KINETIS_KL) // {V1.19} {V1.27}
        fnConfigRTS_delay(ucMODBUSport, &tInterfaceParameters);
        #endif

which excludes this option on KE and KL Kinetis parts that have no automatic RTS line control.

Regards

Mark
