Add intensity control for RGB led
Bump up the default brightness from 64 to 96
Bumped up SPI BaudRate and GPIO Speed for both CC3000 and sFlash
Merge pull request #3 from timothybrown/master

Fixed I2C 7-Bit Addressing
Remove unused defines with names that too easily conflict
Change intensity to brightness for LED control
Fix TIM1 timer prescaler is computed incorrectly

Previous implementation had an error in computing the TIM1 prescaler,
though it was not noticable because the prescaler was large. With a
smaller prescaler (7200 -> 72), the off by one causes the TIM1
period to be a few % less than 1 second. This can be seen in the fade
rate of the LED.
CC3000 driver update - Magic number for detection of the buffer overrun

Fix TIM1 timer prescaler is computed incorrectly
Revert "CC3000 driver update - Magic number for detection of the buffer overrun"

This reverts commit 48a5b0a255135595be4d879c3456cc629c240869.
Make SPI chip select operations atomic
Revert "Make SPI chip select operations atomic"

This reverts commit a7c397b1d2808acebf864c2a721cb19897b887ae
which seems not to help solve the CFOD bug
and also makes OTA updates much slower.
