When you get this well-designed 8051 development platform, we suggest you to:
1) Spend about 1 hour on reading through user guide and related references.
2) Learn the function and principle of each key, modules, and basic operations of this platform.
3) Use self-testing program inside the Disk-CD to check the platform.
4) Choose and experiment the most suitable example in this suite. After the example works ok, think about why the program is written like that? Is there any better solution in programming? Re-write the program yourself, and redo the experiment.
