====== Peripheral Input ======
This block allows to read a signal from some hardware source. This could be a simple digital input or an analog input. Such a block will always read from an input defined in the [[eeros_architecture:hal:start|]].
The constructor of this block looks like 
<code cpp>
PeripheralInput(std::string id, bool exclusive = true);
</code>
As a parameter you must indicate the designator of the corresponding input in the [[eeros_architecture:hal:start|]]. Please make sure that the name is identical to the name in the [[eeros_architecture:hal:start|]]. If not the constructor will throw a fault. A second optional parameter indicates if the input has exclusive rights on the signal defined in the HAL.
Create a new input with 
<code cpp>
PeripheralInput<> position("anIn0"); // anIn0 must be defined in hardware configuration file
PeripheralInput<bool> switch("dIn2"); // dIn2 must be defined in hardware configuration file
</code>
