H A Dgpioiic.430 .Nd GPIO I2C bit-banging device driver
35 .Bd -ragged -offset indent
45 .Bd -literal -offset indent
51 driver provides an IIC bit-banging interface using two GPIO pins for the
52 SCL and SDA lines on the bus.
55 simulates an open collector kind of output when managing the pins on the
56 bus, even on systems which don't directly support configuring gpio pins
58 The pins are never driven to the logical value of '1'.
59 They are driven to '0' or switched to input mode (Hi-Z/tri-state), and
