Detailed Description

template<class I2cMaster, uint8_t NestingLevels = 10, class Transaction = I2cWriteReadTransaction>
class modm::I2cDevice< I2cMaster, NestingLevels, Transaction >

Base class of an I2C Device.

This class provides functions for configuring the adapter and peripheral and starting transactions. It also provides a basic ping() resumable function, which checks if the device responds to its address.

You need to provide the number of required nesting levels for your driver here. By default, 10 levels are chosen, which should be more than enough in any case.

You can choose to use your own custom I2c Transaction Adapter, by providing a class subclassed from an existing I2cAdapter or which implements the I2cTransaction interface manually.

Template Parameters

I2cMaster	an I2cMaster conforming to the I2cMaster interface.
NestingLevels	number of nesting levels required for your driver
Transaction	a class conforming to the I2cTransaction interface.
