Types ¶
type Devfs ¶
type Devfs struct {
// Dev is the I2C bus device, e.g. /dev/i2c-1. Required.
Dev string
}
Devfs is an I2C driver that works against the devfs. You need to load the "i2c-dev" kernel module to use this driver.
type Device ¶
type Device struct {
// contains filtered or unexported fields
}
Device represents an I2C device. Devices must be closed once they are no longer in use.
func Open ¶
Open opens a connection to an I2C device. All devices must be closed once they are no longer in use. For devices that use 10-bit I2C addresses, addr can be marked as a 10-bit address with TenBit.
Example ¶
package main
import (
"golang.org/x/exp/io/i2c"
)
func main() {
d, err := i2c.Open(&i2c.Devfs{Dev: "/dev/i2c-1"}, 0x39)
if err != nil {
panic(err)
}
// opens a 10-bit address
d, err = i2c.Open(&i2c.Devfs{Dev: "/dev/i2c-1"}, i2c.TenBit(0x78))
if err != nil {
panic(err)
}
_ = d
}
