wbeaumont 0:7cb648bc5c2a 14 /** AT30TSE75x class.
wbeaumont 0:7cb648bc5c2a 15 * Used for interfacing with a AT30TSE75x temperature sensor and ee-prom
wbeaumont 0:7cb648bc5c2a 16 * For version 0.1 inital
wbeaumont 0:7cb648bc5c2a 17 * It has to be used with the https://developer.mbed.org/users/wbeaumont/code/DevInterfaces/ package
wbeaumont 0:7cb648bc5c2a 18 * This includes the "virtual" I2CInterface class that is the interface to the I2C device
wbeaumont 0:7cb648bc5c2a 19 * An implementation of the I2Cinterface class for the MBED can be found at
wbeaumont 0:7cb648bc5c2a 20 * https://developer.mbed.org/users/wbeaumont/code/I2Cinterfaces/
wbeaumont 0:7cb648bc5c2a 21 * ee-prom set / read not tested / implemented.
wbeaumont 0:7cb648bc5c2a 22 * version 0.8 : read of temperature 12 bits, fixed configuration
wbeaumont 0:7cb648bc5c2a 23 * read /write ee-prom
wbeaumont 1:c0db18a0c56b 24 * version 0.86 : added ee-prom write protect mode tested ( un-protect not tested)
wbeaumont 0:7cb648bc5c2a 25 * this code is only tested with the AT30TSE752 version ( 2 KBit version)
wbeaumont 1:c0db18a0c56b 26 *
wbeaumont 1:c0db18a0c56b 27 * processor board for the testing : FRDM-KL25Z
