pyrc3563's Introduction

pyrc3563

Python library and CLI tool for RC3563 battery impedance meter.

Library usage

from rc3563 import RC3563

rc = RC3563("/dev/ttyUSB0")
while True:
    print(rc.read())

CLI tool

python -m cli /dev/ttyUSB0
# V: 4.118, R: 0.028483 # 28.483 mΩ
# V: 4.118, R: 0.028376 # 28.376 mΩ
# V: 4.118, R: 0.028264 # 28.264 mΩ
# V: 0.000, R: inf # overflow - nothing connected

Typo?

Typo in README.md??
pyrc3586 vs. pyrc3563??

Hi Krystian,
i do the simple Test to modify your Cod to Pause readings for 5 seconds.
I see with this methode reading is not actuall after change object (Resistor).
Do i stop Programm and restart it is a correct Measurement.

My Plan:
I wanted to delay the measurement to change the measurement object (from cell to cell).
These values should then be written to a file log. (time,cell,V,R)

Can you tell me how (where) I should put a break?

from rc3563 import *
import time
# import argparse
preset_port = "COM5" # '/dev/ttyUSB0'

def main():
    #argparser = argparse.ArgumentParser(prog="python -m cli")
    #argparser.add_argument("path", help="Serial port path")
    #args = argparser.parse_args()
    rc = RC3563(preset_port)
    while True:
        pkt = rc.read()
        time.sleep(5.5) # Pause 5,5 sec
        print(f"V: {pkt.voltage_v:.3f}, R: {pkt.resistance_ohm:.6f}")
        
main()
