QHsmTst is a contrived state machine from Chapter 2 of the PSiCC2 book for testing all possible transition topologies with up to 4-levels of state nesting. Test active object : QHsm(Q_STATE_CAST(&QHsmTst::initial)) (void)e; // unused parameter m_foo = 0U; BSP_display("top-INIT;"); BSP_display("s-ENTRY;"); BSP_display("s-EXIT;"); BSP_display("s-INIT;"); m_foo m_foo = 0U; BSP_display("s-I;"); BSP_display("s-E;"); BSP_terminate(0); BSP_display("s1-ENTRY;"); BSP_display("s1-EXIT;"); BSP_display("s1-INIT;"); BSP_display("s1-I;"); !m_foo m_foo = true; BSP_display("s1-D;"); BSP_display("s1-A;"); BSP_display("s1-B;"); BSP_display("s1-F;"); BSP_display("s1-C;"); BSP_display("s11-ENTRY;"); BSP_display("s11-EXIT;"); BSP_display("s11-H;"); m_foo m_foo = false; BSP_display("s11-D;"); BSP_display("s11-G;"); BSP_display("s2-ENTRY;"); BSP_display("s2-EXIT;"); BSP_display("s2-INIT;"); !m_foo m_foo = true; BSP_display("s2-I;"); BSP_display("s2-F;"); BSP_display("s2-C;"); BSP_display("s21-ENTRY;"); BSP_display("s21-EXIT;"); BSP_display("s21-INIT;"); BSP_display("s21-G;"); BSP_display("s21-A;"); BSP_display("s21-B;"); BSP_display("s211-ENTRY;"); BSP_display("s211-EXIT;"); BSP_display("s211-H;"); BSP_display("s211-D;"); #ifndef QHSMTST_HPP #define QHSMTST_HPP enum QHsmTstSignals { A_SIG = QP::Q_USER_SIG, B_SIG, C_SIG, D_SIG, E_SIG, F_SIG, G_SIG, H_SIG, I_SIG, TERMINATE_SIG, IGNORE_SIG, MAX_SIG }; extern QP::QHsm * const the_hsm; // opaque pointer to the test HSM // BSP functions to dispaly a message and exit void BSP_display(char_t const *msg); void BSP_terminate(int16_t const result); #endif // QHSMTST_HPP #include "qpcpp.hpp" #include "qhsmtst.hpp" $declare(HSMs::QHsmTst) static QHsmTst l_hsmtst; // the only instance of the QHsmTst class // global-scope definitions ----------------------------------------- QP::QHsm * const the_hsm = &l_hsmtst; // the opaque pointer $define(HSMs::QHsmTst)
