ThingMagic Mercury API v1.23.0 - Manual (Page 98)

Build Considerations
98 C Language Interface
#define TMR_ENABLE_SERIAL_TRANSPORT_LLRP //not currently supported
#define TMR_ENABLE_ISO180006B
#define TMR_ENABLE_BACKGROUND_READS //not supported on Windows
#define TMR_ENABLE_ERROR_STRINGS
#define TMR_ENABLE_PARAM_STRINGS
#define TMR_SR_MAX_ANTENNA_PORTS
The minimum #defines that must currently be specified are:

TMR_ENABLE_SERIAL_READER - enables support for the ThingMagic serial
command protocol, but does not specify how that reader is connected. This is
factored out into a "serial transport" layer to allow for future alternatives to the
*_NATIVE interface.

TMR_ENABLE_SERIAL_TRANSPORT_NATIVE - supports standard serial ports
(both UART-based and USB - anything that goes through the OS native serial driver.)
Protocol-Specific C Compilation Options
Gen2 and iPX protocol support are included in all builds and cannot be excluded but
ISO18000-6B protocol may be disabled (TMR_ENABLE_ISO180006B) when building the
C API.
