Not needed, set to 921600 BAUD - LED1 slowly gets brighter and dimmer as main loop runs - If for some reason, the \"MeterNumber\" int register ends up >100 or <0, a Purple display appears at 50% movement with a \"bad#\" scale factor - There is NO provision for setting the RTC. Note that TimeZone and DST are added to the RTC number

loopsva 0:fc70640071d2 4 100 1/30/12 - ANALOG METER, initial offering
loopsva 0:fc70640071d2 5 - Emulation of an analog/mechanical meter using the SPI TFT display "http://mbed.org/cookbook/SPI-driven-QVGA-TFT" (touch not used)
loopsva 0:fc70640071d2 6 Meter takes an integer number from 0 - 100 and uses that number to position the meter's needle
loopsva 0:fc70640071d2 7 - An additional auto-scaling feature allows for + floating numbers from 0.0 - 10000.0 in "NewfNumb"
loopsva 0:fc70640071d2 8 Scaling is noted two ways
loopsva 0:fc70640071d2 9 a. Color of the meter body changes
loopsva 0:fc70640071d2 10 b. A text scale factor is displayed in the upper, right-hand corner, near the full scale reading
loopsva 0:fc70640071d2 11 Value of "NewfNumb" Meter_Body Scale_Factor
loopsva 0:fc70640071d2 12 < -0.0 Blue 0
loopsva 0:fc70640071d2 13 0.1 - 9.9 Green x1
loopsva 0:fc70640071d2 14 10.0 - 99.0 Yellow x10
loopsva 0:fc70640071d2 15 100.0 - 999.0 Orange x100
loopsva 0:fc70640071d2 16 1000.0 - 9990.0 Red x1k
loopsva 0:fc70640071d2 17 >= 10000.0 Red peg!
loopsva 0:fc70640071d2 18 - If NewfNumb is > 600.0, a flashing yellow warning message appears in the center of the meter movement
loopsva 0:fc70640071d2 19 - The date and time are displayed in the lower right corner of the display
loopsva 0:fc70640071d2 20 - The value of NewfNumb being shown in the movement is also displayed in the lower left coener of the display
loopsva 0:fc70640071d2 21 - A timer ISR automatically updates the meter's movement
loopsva 0:fc70640071d2 22 Other Stuff:
loopsva 0:fc70640071d2 23 - Additional demo test program, walks analog meter up and down through all auto scales by manipulating the value of NewfNumb
loopsva 0:fc70640071d2 24 - USB serial port used to dump a few messages. Not needed, set to 921600 BAUD
loopsva 0:fc70640071d2 25 - LED1 slowly gets brighter and dimmer as main loop runs
loopsva 0:fc70640071d2 26 - If for some reason, the "MeterNumber" int register ends up >100 or <0,
loopsva 0:fc70640071d2 27 a Purple display appears at 50% movement with a "bad#" scale factor
