nucho 0:3c49891bc39d 21 * RTno is RT-middleware and arduino.
nucho 0:3c49891bc39d 22 *
nucho 0:3c49891bc39d 23 * Using RTno, arduino device can communicate any RT-components
nucho 0:3c49891bc39d 24 * through the RTno-proxy component which is launched in PC.
nucho 0:3c49891bc39d 25 * Connect arduino with USB, and program with RTno library.
nucho 0:3c49891bc39d 26 * You do not have to define any protocols to establish communication
nucho 0:3c49891bc39d 27 * between arduino and PC.
nucho 0:3c49891bc39d 28 *
nucho 0:3c49891bc39d 29 * Using RTno, you must not define the function "setup" and "loop".
nucho 0:3c49891bc39d 30 * Those functions are automatically defined in the RTno libarary.
nucho 0:3c49891bc39d 31 * You, developers, must define following functions:
nucho 0:3c49891bc39d 32 * int onInitialize(void);
nucho 0:3c49891bc39d 33 * int onActivated(void);
nucho 0:3c49891bc39d 34 * int onDeactivated(void);
nucho 0:3c49891bc39d 35 * int onExecute(void);
nucho 0:3c49891bc39d 36 * int onError(void);
nucho 0:3c49891bc39d 37 * int onReset(void);
nucho 0:3c49891bc39d 38 * These functions are spontaneously called by the RTno-proxy
nucho 0:3c49891bc39d 39 * RT-component which is launched in the PC.
