Yann 0:311a0646b95a 29 * 2. Edit this library
Yann 5:7ddb6bca6d01 30 * 3. Remove comment from line 66 (search for '//#define __DEBUG' in this file) to get the DEBUG macro defimed properly. By default, __DEBUG flahg is undef
Yann 0:311a0646b95a 31 * 4. Rebuild this library and use the debug macro as decribe in sample code
