Member Typedef Documentation

using modm::Fiber< fiber::StackSizeDefault >::binary_semaphore = counting_semaphore<1>
inherited

Implements the std::binary_semaphore interface for fibers.

using modm::Fiber< fiber::StackSizeDefault >::id = uintptr_t
inherited

Identifier of a fiber task.

Member Enumeration Documentation

enum modm::Fiber::Start
inheritedstrong

The Fiber scheduling policy.

Constructor & Destructor Documentation

template<typename I2cMaster >
modm::Tmp175< I2cMaster >::Tmp175 ( Data &  data,
uint8_t  address = 0x48 
)

Constructor, requires a tmp175::Data object, sets address to default of 0x48 (alternatives are 0x49, 0x4A and 0x4B).

Member Function Documentation

void modm::I2cDevice< I2cMaster, 10 , I2cWriteReadTransaction >::attachConfigurationHandler ( I2c::ConfigurationHandler  handler)
inheritedinline

Attaches a configuration handler, which is called before a transaction, whenever the configuration has to be changed.

modm::fiber::id modm::fiber::Task::get_id ( ) const
inheritednodiscardinline

Returns a value of std::thread::id identifying the thread associated with *this.

Note
This function can be called from an interrupt.
bool modm::fiber::Task::isRunning ( ) const
inheritednodiscardinline
Returns
if the fiber is attached to a scheduler.
bool modm::I2cDevice< I2cMaster, 10 , I2cWriteReadTransaction >::isTransactionRunning ( )
inheritedinlineprotected
Returns
true when transaction is busy.
void modm::fiber::Task::join ( )
inheritedinline

Blocks the current fiber until the fiber identified by *this finishes its execution. Returns immediately if the thread is not joinable.

modm::ResumableResult<bool> modm::I2cDevice< I2cMaster, 10 , I2cWriteReadTransaction >::ping ( )
inheritedinline
Return Values
truedevice responds to address
falseno device with address found
bool modm::fiber::Task::request_stop ( )
inheritedinline
Note
This function can be called from an interrupt.
void modm::I2cDevice< I2cMaster, 10 , I2cWriteReadTransaction >::setAddress ( uint8_t  address)
inheritedinline

Sets a new address of the slave device.

Parameters
addressthe slave address not yet shifted left (address < 128).
size_t modm::fiber::Task::stack_usage ( ) const
inheritednodiscardinline
Returns
the stack usage as measured by a watermark level.
See also
modm_context_stack_usage().
void modm::fiber::Task::stack_watermark ( )
inheritedinline

Watermarks the stack to measure stack_usage() later.

See also
modm_context_stack_watermark().
bool modm::fiber::Task::start ( )
inherited

Adds the task to the currently active scheduler, if not already running.

Returns
if the fiber has been scheduled.
bool modm::I2cDevice< I2cMaster, 10 , I2cWriteReadTransaction >::wasTransactionSuccessful ( )
inheritedinlineprotected
Returns
true when transaction did not return an error.

Member Data Documentation

constexpr size_t modm::Fiber< fiber::StackSizeDefault >::StackSizeDefault
inheritedstaticconstexpr

The default stack size is estimated experimentally so that a fiber can use modm::IOStream to log out information, which is fairly stack intensive. Use modm::fiber::Task::stack_usage() to determine the real stack usage.
