			== Summary ==

			* Running From Battery => 4MHz (always)
			* Test Suite Firmware powered from USB => 4MHz
			* KontroLIR firmware powered from USB or battery => 4MHz
			* AnalysIR firmware powered from USB =>16MHz
			* Sketches other than the above combinations running from USB => 16MHz or any supported clock rate if you know what you are doing.

	The clock rate ~~can~~ be set to ~~'''8Mhz''' or~~ '''4MHz''' using the Arduino IDE.		The default clock rate should be set to '''4MHz''' using the Arduino IDE when running from batteries. ''(Option under Tools menu for ATmega328PB)''

	~~Using~~ 8Mhz ~~will~~ provide ~~the best~~ IR performance, while 4MHz ~~may~~ provide a ~~slightly~~ longer battery life. Do not use any other clock rate.		Advanced users may try using the 8Mhz clock rate or when powered from USB during testing. However, we have not tested battery use @ 8MHz and is not supported at this time.

			A clock rate of 8Mhz may provide better IR performance, while 4MHz will provide a longer battery life. Do not use any other clock rate when running on batteries.

	''Note: The granularity of the Arduino micros() function, increases as the clock rate changes from 16MHz to 8MHz to 4Mhz to 1Mhz. This has a knock on effect on the IR signal timing. Running on 2xAAA batteries, 16MHz is out of spec & at 1Mhz the IR performance is materially impacted by the granularity of the Arduino timing.''

	Thus we strongly suggest using '''~~8MHz~~''' as the default clock rate, which provides a good balance between IR performance and battery rate. If you know your way around low power operation & want to drain the last bit of juice from the batteries ,then it is Ok to consider 4MHz. In our opinion, it would be preferable to swap out the batteries a little sooner and enjoy the better IR performance/experience.		Thus we strongly suggest using '''4MHz''' as the default clock rate, which provides a good balance between IR performance and battery life.

The clock rate can be set to 8Mhz or 4MHz using the Arduino IDE.

Using 8Mhz will provide the best IR performance, while 4MHz may provide a longer battery life. Do not use any other clock rate.

''Note: The granularity of the micros() function, increases as the clock rate changes from 16MHz to 8MHz to 4Mhz to 1Mhz. This has a knock on effect on the IR signals timing. Running on batteries, 16MHz is out of spec & at 1Mhz the IR performance is materially impacted by the granularity of the Arduino timing.''

Thus we strongly suggest using 8MHz as the default clock rate, which provides a good balance between IR performance and battery rate. If you know your way around low power operation & want to drain the last bit of juice from the batteries ,then it is Ok to consider 4MHz. In our opinion, it would be preferable to swap out the batteries a little sooner and enjoy the better IR performance/experience.
