Function Documentation

void debugAndHeartbeat

(

heartbeatState_t *

heartbeatStatePtr

)

This function implements the debug-logic.

In Debug-mode, the registers are read and set in predefined intervals. It automatically calls the nextHeartbeatStep()-function to change the states.

subfunction	state
next heartbeat-step	every
check Run-Bit in ctrlReg	every
check Dir-Bit in ctrlReg	every
set stepsReg (+10 / -10)	every
set IR-Bit in ctrlReg	FOURTH

Parameters

heartbeatStatePtr

Points to the state-structure containing the actual state.

Here is the call graph for this function:

void HeartbeatTask

(

void *

pdata

)

The task for the hearbeat and the debug-mode.

This task is doing a heartbeat to show scheduling is working. Therefore changes its state every second via the nextHeartbeatStep()-function. When the UserInputTask detects, that the user activated the Debug-Mode, it sends the DEBUG_ON_EVENT. The task then calls the debugAndHeartbeat()-function.

Parameters

pdata

: Pointer to parameter structure (not used)

Definition at line 29 of file heartbeatTask.c.

Here is the call graph for this function:

void nextHeartbeatStep

(

heartbeatState_t *

heartbeatStatePtr

)

State machine for the heartbeat.

The state machine activates and deactivates the red LED9 and shows the defined HEX-values (LOWER_O, UPPER_O and LINE) on HEX3 accordingly after 1 second.

Parameters

heartbeatStatePtr

Points to the state-structure containing the actual state.
