Code and Syntax Examples

from deltaelektronika import SM15K
import time

# IP Address of the power supply, can be obtain the device itself.
IPV4 = '0.0.0.0' 

# To activate debugging option. Creates systemlog file and logs there
#SM15K.activateDebugLogger = True 

# To deactivate debugging option. Creates systemlog file and logs there
SM15K.activateDebugLogger = False 

ColorPrint = SM15K.ColorPrinter()

#Be sure Watchdog timer is higher than sleeptime of the thread
Watchdog = SM15K.WatchdogOperation(IPV4, timer=5000, sleeptime=4)  

# Default color is green, available colors are;
# purple, blue, cyan, green, yellow, red and normal                            
BasicDatalogger = SM15K.BasicDataloggerOperation(IPV4, loggingTime=10,
                printColor= 'purple')    
                
# Default color is green, available colors are;
# purple, blue, cyan, green, yellow, red and normal 
AhDatalogger = SM15K.AhDataloggerOperation(IPV4, loggingTime=10, 
                printColor= 'red')
 
# Default color is green, available colors are;
# purple, blue, cyan, green, yellow, red and normal            
WhDatalogger = SM15K.WhDataloggerOperation(IPV4, loggingTime=5, 
                printColor='blue')  
                            
Charging = SM15K.ChargingOperation(IPV4, sleeptime=5, bulkCurrent=100, 
                bulkVoltage= 14.5, floatVoltage=13.8, floatTime=300)
                
Discharging = SM15K.DischargingOperation(IPV4, sleeptime=5, 
                dischargeCurrent=100, dischargeVoltage=10.5, 
                cutoffCurrent=2)
                
Cycling = SM15K.CyclingOperation(IPV4, sleeptime=5, cycletime=10, 
                bulkCurrent=100, bulkVoltage=14.5, floatVoltage=13.8, 
                floatTime=300, dischargeCurrent=100, 
                dischargeVoltage=10.5, cutoffCurrent=2, restTime=30)

Each functionality has been created with related parameters at above.
To be able to use them python object.start() must be used to start the thread operation

Watchdog.start()        # To start watchdog thread class
BasicDatalogger.start() # To start BasicDatalogger thread class
AhDatalogger.start()    # To start AhDatalogger thread class
WhDatalogger.start()    # To start WhDatalogger thread class
Charging.start()        # To start Charging thread class
Discharging.start()     # To start Discharging thread class
Cycling.start()         # To start Cycling thread class

After calling thread start, if main loop ends, thread is going to end as well because of being deamong thread true. That is why infinity loop or long term loop needed to run. Or it can be used as thread.join() to be sure that main does not end before the thread is done.

Note: Do not operate charging and discharging threads at the same operation.

Note: Do not operate Ah and Wh datalogger threads at the same operation. Delta can log one of them at a time.

Note: Watchdog is being set to delta itself, that is why be sure timer is bigger than sleep time to have healty operation.

while True:
    # Main Code Runs Here in infinity loop.
    time.sleep(30)
    print(f'Main loop runs in here!')

You can run anything you want here as well to have multifunctional operation while system runs with multiple threads.

Note: All threads are created as deamon thread which means, if main finishes its operation threads are going to stop operation. That is why you should keep them in infinite loop.
