A new CodeWarrior and Embedded SDK training exercise has been added.
In Exercise 3d you learn how to write a low level driver for the
EVM's debug LED(s), which are attached to specific GPIO pins. Also
provided are modified Appendix C programmer's sheets showing SDK
support. Stand alone assembly programming is supported by registers.h
files for each DSP. This exercise covers how to write GPIO drivers.
Its basic principles can be applied to writing drivers for all other

If you search for "simple peripheral drivers" you will find another
example of low-level drivers, this time involving LEDs, timers, and
