# go-mcp23017
GoLang MCP23017 driver that uses Linux I2C calls
Based on Adafruit Arduino Implementation: https://github.com/adafruit/Adafruit-MCP23017-Arduino-Library/
# Example Usage
This code snippet turns on each I/O sequentially and then turns off.
```go
package main
import (
"github.com/quan-to/slog"
"github.com/racerxdl/go-mcp23017"
"time"
)
var log = slog.Scope("TEST")
func main() {
d, err := mcp23017.Open(1, 0)
if err != nil {
log.Error(err)
}
defer d.Close()
for i := 0; i < 16; i++ {
err := d.PinMode(uint8(i), mcp23017.OUTPUT)
if err != nil {
log.Error(err)
}
}
for {
log.Info("Turning On")
for i := 0; i < 16; i++ {
err = d.DigitalWrite(uint8(i), mcp23017.HIGH)
if err != nil {
log.Error(err)
}
time.Sleep(time.Millisecond * 100)
}
time.Sleep(time.Second)
log.Info("Turning Off")
for i := 0; i < 16; i++ {
err = d.DigitalWrite(uint8(i), mcp23017.LOW)
if err != nil {
log.Error(err)
}
time.Sleep(time.Millisecond * 100)
}
}
}
```
