Title: SPI flash read and write
Description:
A simple spi flash example using the microkernel.
--------------------------------------------------------------------------------
Building and Running Project:
This microkernel project outputs to the console. It can be built and executed
on arduino_101 as follows:
make BOARD=arduino_101
--------------------------------------------------------------------------------
Troubleshooting:
Problems caused by out-dated project information can be addressed by
issuing one of the following commands then rebuilding the project:
make clean # discard results of previous builds
# but keep existing configuration info
or
make pristine # discard results of previous builds
# and restore pre-defined configuration info
--------------------------------------------------------------------------------
Sample Output:
SPI flash testing!
data sent ..
data received ...
