LTC2487/LTC2487.h@17:5098d8fbb298, 2018-06-15 (annotated)

Revision:
17:5098d8fbb298
Parent:
0:a28a1035c31b 
Updated the LTC2487 library to write all the addresses for a row, wait for next clock cycle of chip (15Hz), and read all the channels. This significantly sped up the thermocouple read time. Both the LTC2487 library and the read functions were changed
