Detailed Description

General Purpose Timer 14

Interrupt handler:

MODM_ISR(TIM14)
{
    Timer14::resetInterruptFlags(Timer14::...);
 
    ...
}

Warning: The Timer has much more possibilities than presented by this interface (e.g. Input Capture, Trigger for other Timers, DMA). It might be expanded in the future.

Member Enumeration Documentation

enum modm::platform::GeneralPurposeTimer::InputCaptureMapping : uint32_t

inheritedstrong

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.

enum modm::platform::GeneralPurposeTimer::Mode : uint32_t

inheritedstrong

Enum Values	Documentation
CenterAligned1	Output compare flags only set when counting down.
CenterAligned2	Output compare flags only set when counting up.
CenterAligned3	Output compare flags set when counting up and down (default)

enum modm::platform::GeneralPurposeTimer::OutputCompareMode : uint32_t

inheritedstrong

Enum Values	Documentation
Inactive	Output is independent from the compare result.
HighOnMatch	Output is forced high on match.
LowOnMatch	Output is forced low on match.
Toggle	Output is toggled on match.
ForceInactive	Output is forced low.
ForceActive	Output is forced high.
Pwm	PWM Mode 1. While up-counting, channel is active as long as count is less than channel capture/compare register, else inactive. In downcounting, channel is inactive as long as count exceeds capture/compare register, else active
Pwm2	PWM mode 2. In upcounting, channel is inactive as long as count is less than capture/compare register, else active. In downcounting, channel is active as long as count exceeds capture/compare register, else inactive.

enum modm::platform::Timer14::SlaveMode : uint32_t

strong

Enum Values	Documentation
Disabled	Slave mode disabled - if CEN = '1' then the prescaler is clocked directly by the internal clock.
Encoder1	Counter counts up/down on TI2FP2 edge depending on TI1FP1 level.
Encoder2	Counter counts up/down on TI1FP1 edge depending on TI2FP2 level.
Encoder3	Counter counts up/down on both TI1FP1 and TI2FP2 edges depending on the level of the other input.
Reset	Rising edge of the selected trigger input (TRGI) reinitializes the counter and generates an update of the registers.
Gated	The counter clock is enabled when the trigger input (TRGI) is high. The counter stops (but is not reset) as soon as the trigger becomes low. Both start and stop of the counter are controlled.
Trigger	The counter starts at a rising edge of the trigger TRGI (but it is not reset). Only the start of the counter is controlled.
ExternalClock	Rising edges of the selected trigger (TRGI) clock the counter.

TODO Description

static void modm::platform::GeneralPurposeTimer::configureOutputChannel	(	uint32_t	channel,
		OutputCompareMode_t	mode,
		uint16_t	compareValue
	)

inheritedstatic

Configure output channel 1..4.

Parameters

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

static void modm::platform::BasicTimer::enableInterruptVector	(	bool	enable,
		uint8_t	priority
	)

inheritedstatic

Enables or disables the Interrupt Vector.

Parameters

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

static void modm::platform::Timer14::forceActive ( uint32_t channel )

inlinestatic

Switch to Active Mode

The channel output will be forced to the active level. Please note: Timer will not be disabled while switching modes.

static void modm::platform::Timer14::forceInactive ( uint32_t channel )

inlinestatic

Switch to Inactive Mode

The channel output will be forced to the inactive level. Please note: Timer will not be disabled while switching modes.

static bool modm::platform::Timer14::isChannelConfiguredAsInput ( [[maybe_unused] ] uint32_t channel = 1 )

inlinestatic

Returns if the capture/compare channel of the timer is configured as input.

Parameters

channel is not used

Returns: false if configured as output; true if configured as input

static void modm::platform::Timer14::setInvertedPwm ( uint32_t channel )

inlinestatic

Switch to Pwm Mode 2

While upcounting channel will be active as long as the time value is smaller than the compare value, else inactive. Timer will not be disabled while switching modes.

static void modm::platform::BasicTimer::setMode ( Mode mode )

inheritedstatic

Set operation mode of the timer

static void modm::platform::GeneralPurposeTimer::setMode	(	Mode	mode,
		SlaveMode	slaveMode = `SlaveMode::Disabled`,
		SlaveModeTrigger	slaveModeTrigger = `(SlaveModeTrigger) 0`
	)

inheritedstatic

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).

static void modm::platform::Timer14::setNormalPwm ( uint32_t channel )

inlinestatic

Switch to Pwm Mode 1

While upcounting channel will be inactive as long as the time value is smaller than the compare value, else active. Please note: Timer will not be disabled while switching modes.
