History

Made 3 major changes:; 1. Updated how we read temperatures (I2C write all channel, than read all channels); 2. Got rid of inner cooling loop that stopped control loop if the channel was cooling and really close to set point ; 3. Send all temp. data default tip

Latest C code revision with faster temperature reads, sending all channel temperatures for logging, and optimization of control loop (removal of inner chiller control)

Updated: get_current functions to work with new LTC layout, got rid of timer on the cooling loop

Updated: get_current functions to work with new LTC layout, got rid of timer on the cooling loop

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

Added function to send all temperature data over serial for logging;

Reduced the number of print statements in an attempt to limit the amount of data on the serial lines (used to help with the connection serial reliability)

Latest Revision running on Test Rack. This is Justin's final revision of the C code, needs to be merged with Huyen's code and than this will become the final version
