+ This simple sketch does the next:
+ 1.- init/Clear EEPROM buffer with 0xFF - EEPROM buffer size is 2048 (2k)
+ 2.- write data 10 times to EEPROM buffer "0123456789"
+ 3.- compare EEPROM buffer contents with EEPROM PAGE0, if equal go to step 7, if not continue to step 4
+ 4.- erase EEPROM PAGE0
+ 5.- save current EEPROM buffer contents(100 x "0123456789") to EEPROM PAGE0
+ 6.- compare again EEPROM buffer contents with EEPROM PAGE0
+ 7.- show results on display
+ 8.- end
+ 
+- once executed the above, remove power from SmartGPU and run sketch again, EEPROM contents will remain as they are non-volatile data
