Hey guys,
can u tell me how to get the Firmware Version from die I2C.

I tried this.
Code: Select all
import smbus
addr=0x10 #ups i2c address
bus=smbus.SMBus(1) #i2c-1

capacity=(((vcellH&0x0F)<<8)+vcellL)*1.25 #capacity
electricity=((socH<<8)+socL)*0.003906 #current electric quantity percentage

print("firmware=", firmware)
print("electricity percentage=%.2f"%electricity)
But im kinda missing something.

Thanks for your help :)

I suggest you use
Code: Select all
list = bus.read_i2c_block_data(addr, 0x00) 
This instruction will get a list, including the data of 0x00, 0x01, 0x02 and so on
