Implementation of the parent device

This section looks at the basic implementation of the parent device.

cbAppColdStart()

The application ID and channel are determined here. The initialization process is described in the vProcessEvCore() function.

void cbAppColdStart(bool_t bAfterAhiInit) {
    if (!bAfterAhiInit) { // before AHI init, very first of code.
        // Register modules
        ToCoNet_REG_MOD_ALL();
    } else {
        // TWELITE NET configuration
        sToCoNet_AppContext.u32AppId = 0x12345678;
        sToCoNet_AppContext.u8Channel = 18;
        sToCoNet_AppContext.bRxOnIdle = TRUE;

        // Register user PRSEV.
        ToCoNet_Event_Register_State_Machine(vProcessEvCore);
    }
}

cbToCoNet_vNwkEvent()

The parent machine processes the E_EVENT_TOCONET_NWK_START message.

void cbToCoNet_vNwkEvent(teEvent eEvent, uint32 u32arg) {
    switch (eEvent) {
    case E_EVENT_TOCONET_NWK_START:
        // send this event to the local event machine.
        ToCoNet_Event_Process(eEvent, u32arg, vProcessEvCore);
        break;
    default:
        break;
    }
}

cbToCoNet_vRxEvent()

The receiving method is much the same as for simple nets. There is a difference in the tsRxDataApp structure.

void cbToCoNet_vRxEvent(tsRxDataApp *pRx) {
    uint8 *p = pRx->auData;

    // View packets
    if (pRx->u8Cmd == TOCONET_PACKET_CMD_APP_DATA) {
        // Basic information
        uint8 u8lqi_1st = pRx->u8Lqi; // LQI
        uint32 u32addr_1st = pRx->u32SrcAddr; // Sender

        // Interpreting the data
        uint8 u8b = G_OCTET();
        ...
    }
}

vProcessEvCore()

On E_EVENT_START_UP when the system starts, sets the tsToCoNet_NwkLyTr_Config structure, executes the ToCoNet_NwkLyTr_psConfig() function, initializes the network with the ToCoNet_Nwk_bInit() function and starts the network with the ToCoNet_Nwk_bStart() function.

The E_EVENT_TOCONET_NWK_START event is received after the network starts.

static tsToCoNet_NwkLyTr_Config sNwkLayerTreeConfig;
static tsToCoNet_Nwk_Context* pContextNwk;

static void vProcessEvCore(tsEvent *pEv, teEvent eEvent, uint32 u32evarg) {
    switch (pEv->eState) {
    case E_STATE_IDLE:
        if (eEvent == E_EVENT_START_UP) {
            V_PRINTF(LB"[E_STATE_IDLE]");

            // Configure the Network
            sNwkLayerTreeConfig.u8Layer = 0;
            sNwkLayerTreeConfig.u8Role 
                = TOCONET_NWK_ROLE_PARENT;

            pContextNwk =
                ToCoNet_NwkLyTr_psConfig(&sNwkLayerTreeConfig);
            if (pContextNwk) {
                ToCoNet_Nwk_bInit(pContextNwk);
                ToCoNet_Nwk_bStart(pContextNwk);
            }

        } else if (eEvent == E_EVENT_TOCONET_NWK_START) {
            // Transition to the RUNNING state with a START event
            // * Transmission from cbToCoNet_vNwkEvent()
            ToCoNet_Event_SetState(pEv, E_STATE_RUNNING);
        } else {
            ;
        }
        break;

    case E_STATE_RUNNING:
        if (eEvent == E_EVENT_NEW_STATE) {
            V_PRINTF(LB"[E_STATE_RUNNING]");
        } else {
            ; // DO SOMETHING ELSE!
        }
        break;

    default:
        break;
    }
}
