Outputs

Output Name	Type	Description
TimeDiff [ms]	uint32	Conditional output The time difference in milliseconds between successive block executions. This output depends on the Get time difference parameter.
TimeDiff [us]	uint32	Conditional output The time difference in microseconds between successive block executions. This output depends on the Get time difference parameter.
Timer counter	uint32	Conditional output The current raw value of the timer counter. This output depends on the Enable output tick parameter.

Block Parameters

Parameter	Description
Get time difference	Configures the source for the time difference calculation: `millisecond (user timebase source)` – time is returned in milliseconds, measured by the timer specified as the Timebase source in the CubeMX configuration file. `microsecond (use timer)` – time is returned in microseconds, measured by the user-defined timer specified in the Timer parameter.
Enable output tick	Enables or disables the clock counter output port: `Enable` – the output port is enabled. `Disable` – the output port is disabled.
Timer	Conditional Parameter Selects the specific timer hardware used to track the elapsed time. This parameter is accessible when Get time difference is set to `microsecond (use timer)`.
Timer clock [MHz]	Conditional Parameter The clock frequency of the selected timer used for tracking time. This parameter is accessible when Get time difference is set to `microsecond (use timer)`.

H7

No.	Name	Path	Setting	Description
1	Timebase source	Pinout & Configuration > System Core > SYS > Timebase Source	Based on user preference	Conditional Parameter The hardware timer designated as the millisecond timebase source when Get time difference is set to `millisecond (user timebase source)`.
2	Clock Source	Pinout & Configuration > Timers > TIM* > Clock Source	Internal clock	Conditional Parameter The clock source for the timer designated to measure time in microseconds when Get time difference is set to `microsecond (use timer)`.
3	Global interrupt / Update interrupt	Pinout & Configuration > TIM* > NVIC Settings > Global interrupt / Update interrupt	`Enabled`	Conditional Parameter Enables interrupts for the designated timer. Some timers utilize a Global or Update interrupt; one of these options must be enabled.

TIM* / Channel* - the * symbol in the parameter name denotes the specific timer or channel number configured within the block parameters. Depending on your model configuration, multiple parameters might exist for different timers or channels.
