* This is a example sketch showing the basic communication using line by line serial
* communication
* This example skecth needs 5 libraries as you can see below with the includes
* Make sure they are configured and linked to properly
* This example is a follow up of SerialCommunicatorStep2 which is bundled as an example in
* the SerialStringReader library
* This example is seriously different from the previous both in code and as behavior
* as it goes on (or more) level(s) up
* In the previous example we used the line by line serial input of SerialStringReader
* here we still use it but indirectly and as such hidden.
* In this example we still use BlinkLed but then indirectly with BlinkLedSerial.
* BlinkLedSerial derives from BlinkLed and adds the register function.
* The register is the secret to it all.
* Basically the register makes a copy (well it copies the pointers to) of the important
* objects in memory in such a way (read array) that the communicator can loop over it.
* Because the register also provides a name the communicator can output and modify
* any of the registered objects without any additional code.
* It can also DUMP the memory objects it knows which allows for advanced control.
* verify and upload the code; connect with the serial monitor and send following
* lines to the Arduino (do not forget to add a CR or LF or both)
* ?
* -> yes you can even see all commands note that
* -> all the fields with detailed technical info
* -> all the field names the way they are logged in LOG VALUE
* -> Shows all the set commands to get back to how they are set now
* SET Admin.DelaybetweenLogs=5000
* ->notice the slower incoming LOG VALUE strings?
* SET Admin.DelaybetweenLogs=2000
* ->back to normal
* SET Admin.logLevel=0
* ->no more LOG VALUE messages
* SET BuildInLed.OffInterval=200
* ->Do you notice the change in led blinking?
* SET BuildInLed.OnInterval=1000
* ->You must see the led 13 blink different
* while playing around you may have noticed a string similar to the
* following in the serial monitor
* SET Admin.DelaybetweenLogs=2000
* Failed to log: availableForWrite =2 , SerialQueueSize =63
* This is a warning message that when the code wanted to log the values the serial queue
* was not empty. Therefore it will not log but log this error message
* Here it tells there were only 2 bytes available of 63.
* no rights reserved

// The loop function is called in an endless loop

// yes!!!! yes!!! That is all we need in the loop to change the blinking of the led
You can’t perform that action at this time.
