Member Enumeration Documentation

Mode

enum class daisy::I2CHandle::Config::Mode

strong

Specifies whether the interface will operate in master or slave mode.

Enumerator
I2C_MASTER
I2C_SLAVE

Peripheral

enum class daisy::I2CHandle::Config::Peripheral

strong

Specifices the internal peripheral to use (these are mapped to different pins on the hardware).

Enumerator
I2C_1	&
I2C_2	&
I2C_3	&
I2C_4	&

Speed

enum class daisy::I2CHandle::Config::Speed

strong

Rate at which the clock/data will be sent/received. The device being used will have maximum speeds. 1MHZ Mode is currently 886kHz

Enumerator
I2C_100KHZ	&
I2C_400KHZ	&
I2C_1MHZ	&
