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::ResumableResult< ReturnType > resumable modm::NestedResumable< 1 >::function (   ...)
inherited

Run the resumable function.

You need to implement this method in you subclass yourself.

Returns
>NestingError if still running, <=NestingError if it has finished.
int8_t modm::NestedResumable< 1 >::getResumableDepth ( ) const
inheritedinline
Returns
the nesting depth in the current resumable function, or -1 if called outside any resumable function
bool modm::NestedResumable< 1 >::isResumableRunning ( ) const
inheritedinline
Returns
true if a resumable function is running at the current nesting level, else false
bool modm::I2cDevice< I2cMaster, 10 , I2cWriteReadTransaction >::isTransactionRunning ( )
inheritedinlineprotected
Returns
true when transaction is busy.
template<class I2cMaster >
modm::ResumableResult<bool> modm::stts22h< I2cMaster >::readTemperature ( )

Read temperature from device

Precondition
sensor is succesfully initialized
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).
template<class I2cMaster >
modm::stts22h< I2cMaster >::Stts22h ( Data &  data,
uint8_t  address = 0x3f 
)
Parameters
addressI2C address, selectable on device between 0x38 and 0x3f
bool modm::I2cDevice< I2cMaster, 10 , I2cWriteReadTransaction >::wasTransactionSuccessful ( )
inheritedinlineprotected
Returns
true when transaction did not return an error.
