smbus
smbus provides access to the System Management bus, over I2C.
Example
func TestOpen(t *testing.T) {
usr, err := user.Current()
if err != nil {
t.Fatalf("os/user: %v\n", err)
}
if usr.Name != "root" {
t.Skip("need root access")
}
c, err := smbus.Open(0, 0x69)
if err != nil {
t.Fatalf("open error: %v\n", err)
}
defer c.Close()
v, err := c.ReadReg(0x69, 0x1)
if err != nil {
t.Fatalf("read-reg error: %v\n", err)
}
t.Logf("v=%v\n", v)
}

Types ¶
type Conn ¶
type Conn struct {
// contains filtered or unexported fields
}
Conn is connection to a i2c device.
func OpenFile ¶
OpenFile opens a connection to the i2c bus number. Users should call SetAddr afterwards to have a properly configured SMBus connection.
func (*Conn) ReadBlockData ¶
ReadBlockData reads len(buf) data into the byte slice, from the designated register.
func (*Conn) Write ¶
Write sends buf to the remote i2c device. The interpretation of the message is implementation dependant.
func (*Conn) WriteBlockData ¶
WriteBlockData writes the buf byte slice to a designated register.
func (*Conn) WriteByte ¶
WriteByte sends a single byte to the remote i2c device. The interpretation of the message is implementation dependant.
