import struct, setpoint at -15 °C
fixed TEC, now working perfectly
cosmetic changes
added little programm for testing the TEC
- setting TEC setpoint is now working properly
- set default setpoint to -17 which should lead to a TEC temperature of about -15
decided for "struct.pack('<h', int(-5.0 * 10)) --> '0xCEFF'" for setting the TEC setpoint
