Kenji Arai / Mbed 2 deprecated LPC1114_data_logger

Data logger: Sensors -> Barometer & temperature (BMP180), Humidity & temp. (RHT03), Sunshine (Cds): Display -> 20 chracters x 4 lines: Strage -> EEPROM (AT24C1024): Special functions -> Enter sleep mode to save current, reading the logging data via serial line

Dependencies:   AT24C1024 BMP180 M41T62 RHT03 TextLCD WakeUp mbed

Fork of LPC1114_barometer_with_data_logging by Kenji Arai
