_I2CGPIO_DEVICE Struct Reference

#include <i2cgpio.h>

Data Fields
I2C_DEVICE	i2c
GPIO_DEVICE *	gpio
	The GPIO device this device is connected to.
uint32_t	sda
	GPIO pin for the SDA line.
uint32_t	scl
	GPIO pin for the SCL line.
uint32_t	delay
	Clock and Data delay in microseconds.
uint32_t	timeout
	Clock timeout in milliseconds.
LONGBOOL	outputonly
	Clock line is output only, no test for SCL high.
LONGBOOL	opendrain
	Clock and Data are open drain, no need to simulate by switching direction.
LONGBOOL	ignorenak
	If True Ignore NAK responses and continue.
