Detailed Description

General Purpose Timer 17

Interrupt handler:

MODM_ISR(TIM17)
{
Timer17::resetInterruptFlags(Timer17::...);
...
}
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 ValuesDocumentation
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 ValuesDocumentation
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::Timer17::SlaveMode : uint32_t
strong
Enum ValuesDocumentation
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]
modeOutput compare mode
compareValuePreloaded 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
enableEnable/disable the interrupt vector
priorityPriority of the interrupt vector (0=highest to 15=lowest).
static void modm::platform::Timer17::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::Timer17::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::Timer17::isChannelConfiguredAsInput ( uint32_t  channel)
static

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

Parameters
channelis not used
Returns
false if configured as output; true if configured as input
static void modm::platform::Timer17::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::Timer17::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.
