emmanuelchio 0:1e62f3fc1154 14 This simple sketch does the next:
emmanuelchio 0:1e62f3fc1154 15 1.- init/Clear EEPROM buffer with 0xFF - EEPROM buffer size is 2048 (2k)
emmanuelchio 0:1e62f3fc1154 16 2.- write data 10 times to EEPROM buffer "0123456789"
emmanuelchio 0:1e62f3fc1154 17 3.- compare EEPROM buffer contents with EEPROM PAGE0, if equal go to step 7, if not continue to step 4
emmanuelchio 0:1e62f3fc1154 18 4.- erase EEPROM PAGE0
emmanuelchio 0:1e62f3fc1154 19 5.- save current EEPROM buffer contents(100 x "0123456789") to EEPROM PAGE0
emmanuelchio 0:1e62f3fc1154 20 6.- compare again EEPROM buffer contents with EEPROM PAGE0
emmanuelchio 0:1e62f3fc1154 21 7.- show results on display
emmanuelchio 0:1e62f3fc1154 22 8.- end
emmanuelchio 0:1e62f3fc1154 23
emmanuelchio 0:1e62f3fc1154 24 - once executed the above, remove power from SmartGPU and run sketch again, EEPROM contents will remain as they are non-volatile data
