Field Documentation

uint16_t I2C_Ack

Enables or disables the acknowledgement. This parameter can be a value of I2C_acknowledgement

uint16_t I2C_AcknowledgedAddress

Specifies if 7-bit or 10-bit address is acknowledged. This parameter can be a value of I2C_acknowledged_address

uint32_t I2C_ClockSpeed

Specifies the clock frequency. This parameter must be set to a value lower than 400kHz

uint16_t I2C_DutyCycle

Specifies the I2C fast mode duty cycle. This parameter can be a value of I2C_duty_cycle_in_fast_mode

uint16_t I2C_Mode

Specifies the I2C mode. This parameter can be a value of I2C_mode

uint16_t I2C_OwnAddress1

Specifies the first device own address. This parameter can be a 7-bit or 10-bit address.
