If capture compare control bit preloading is enabled (CCPC=1), this selects how to update them.

If more than one Compare Channel is available they are always paired. (A channel with an odd number is paired with the next even numbered channel) It is possible to choose as trigger for the input capture functionality either the own timer input or the input associated with the paired channel.

For working with Internal Triggers, TRC can also be selected.

Clears one or multiple flags.

Parameters

flags

Bitmap of StateFlag

Reset the counter, and update the prescaler and overflow values.

Generates an Update-Event without generating an Update-Interrupt.

This will reset the counter to 0 in up-counting mode (the default) or to the maximal value in down-counting mode. It will also update the timer's prescaler and overflow values if you have set them up to be changed using setPrescaler() or setOverflow() (or setPeriod()).

An Update-Event is also generated when the timer reaches its maximal (up-counting) or minimal (down-counting) value. The settings for Prescaler, Overflow and Compare values are applied then without calling this function.

TODO Description

Configure output channel 1..4.

Parameters

channel	[1..4]
mode	Output compare mode
compareValue	Preloaded output compare value (can be changed later via setCompareValue())

Disable clock.

All settings are ignored in this mode and the timer is shut down. Calling any function other than enable() won't have any effect.

Disables interrupts.

Parameters

interrupt

Interrupts to disable

Enables the clock for the timer and resets all settings

Has to be called before calling any other function from this class! Otherwise the settings won't have any effect.

Enables interrupts. Don't forget to enable the Interrupt Vector.

Parameters

interrupt

Interrupts to enable

See also

enableInterruptVector()

Enables or disables the Interrupt Vector.

Parameters

enable	Enable/disable the interrupt vector
priority	Priority of the interrupt vector (0=highest to 15=lowest).

Read compare value for channel 1..4.

Parameters

channel

[1..4]

Returns

Current compare value

Returns a bitmap of the enum StateFlag. Use this method while executing an interrupt or in other situations where you want to know which of the flags are set.

If a flag is a cause of an enabled interrupt (and the Interrupt Vector is enabled) then interrupt will be triggered as long the flag is set.

Warning

You cannot use a switch statement for the returned value, since multiple flags may be set!

Get current overflow

Get current prescaler

Get the counter value

Allows to check, whether the timer has BDTR and DTR2 registers for PWM deadtime, break and output enable control.

Check current count direction

Check, whether clock has been enabled.

Pause timer operation

All settings are stored but the timer operation is suspend until start() is called.

Set compare value for channel 1..4.

Parameters

channel	[1..4]
value	Compare value

Set operation mode of the timer

Set operation mode of the timer

In Encoder mode the encoder channels A and B must be connected to channel 1 and 2 of the timer (e.g. TIM2_CH1 and TIM2_CH2).

Set overflow.

This sets the maximum counter value of the timer. The timer is blocked if overflow is set to zero.

Takes effect at next update event.

See also

applyAndReset()

Set Timer period

Changes prescaler and overflow values. Takes effect at next update event.

Parameters

duration	Requested duration of period
autoApply	Update the new value immediately and reset the counter value.

Returns

New overflow value.

See also

applyAndReset()

Set new prescaler

The prescaler can divide the counter clock frequency by any factor between 1 and 65'536. The new prescaler ratio is taken into account at the next update event.

See also

applyAndReset()

Set a new counter value

Re-enable timer operations

Has to called after the initial configuration to start timer or after pause() to restart the timer.
