##### Note: (From Zipdox2 - See issue #36)
Some AS5600 modules seem to have a resistor between **PGO** and **GND**.
This causes the AS5600 to disable the output (to use it for programming, see datasheet).
This resistor needs to be removed to use the **OUT** pin.

## I2C
The I2C address of the **AS5600** is always 0x36.
#### Address
| sensor | address | changeable |
@ -150,6 +153,32 @@ The **AS5600L** supports the change of I2C address, optionally permanent.
Check the **setAddress()** function for non-permanent change.
#### I2C multiplexing
Sometimes you need to control more devices than possible with the default
address range the device provides.
This is possible with an I2C multiplexer e.g. TCA9548 which creates up
to eight channels (think of it as I2C subnets) which can use the complete
address range of the device.
Drawback of using a multiplexer is that it takes more administration in
your code e.g. which device is on which channel.
This will slow down the access, which must be taken into account when
deciding which devices are on which channel.
Also note that switching between channels will slow down other devices
too if they are behind the multiplexer.
- https://github.com/RobTillaart/TCA9548
Alternative could be the use of a AND port for the I2C clock line to prevent
the sensor from listening to signals on the I2C bus.
Finally the sensor has an analogue output **OUT**.
This output could be used to connect multiple sensors to different analogue ports of the processor.
**Warning**: If and how well this analog option works is not verified or tested.

#### Error handling
Since 0.5.2 the library has added **experimental** error handling.
For now only lowest level I2C errors are checked for transmission errors.
Error handling might be improved upon in the future.
Note: The public functions do not act on error conditions.
This might change in the future.
So the user should check for error conditions.
```cpp
int e = lastError();
if (e != AS5600_OK)
{
// handle error
}
```
- **int lastError()** returns the last error code.
After reading the error status is cleared to **AS5600_OK**.
| Error codes | value | notes |

| AS5600_OK | 0 | default |
| AS5600_ERROR_I2C_READ_0 | -100 |

## Multiplexing
The I2C address of the **AS5600** is always 0x36.
To use more than one **AS5600** on one I2C bus, one needs an I2C multiplexer,
e.g. https://github.com/RobTillaart/TCA9548.
