make: *** [tcpmodbus] Error

三、解决办法：

. modified the file "freemodbus/modbus/include/mbconfig.h"

. find the under code

/*! \brief If Modbus ASCII support is enabled. */

#define MB_ASCII_ENABLED ( 1 )

/*! \brief If Modbus RTU support is enabled. */

#define MB_RTU_ENABLED ( 1 )

/*! \brief If Modbus TCP support is enabled. */

#define MB_TCP_ENABLED ( 0 )

/*! \brief The character timeout value for Modbus ASCII.

change into

#define MB_ASCII_ENABLED ( 0 )

#define MB_RTU_ENABLED ( 0 )

#define MB_TCP_ENABLED ( 1 )
