<p><b>New page</b></p><div>I've been playing with random registers on the i2c-1 0x36 address and I have discovered that channel 0x14 seems to behave like a sort of power consumption meter, can anyone verify this?<br />
<br />
While pulling around 7amps with 4 batteries, this addition to the x750ups.py script works perfectly and seems very accurate! (ymmv depending on battery quantity/quality/health and amperage you are pulling, you may need to play with the values):<br />
<br />
def readStatus(bus):<br />
<br />
address = 0x36<br />
read = bus.read_word_data(address, 0x14)<br />
return struct.unpack("<H", struct.pack(">H", read))[0]<br />
<br />
# ...<br />
<br />
while True:<br />
<br />
status = readStatus(bus)<br />
<br />
# ...<br />
<br />
print "Status:%6i" % status<br />
<br />
# ...<br />
<br />
if status < 512:<br />
<br />
print "USB Power Connected 2A Charging"<br />
<br />
elif status < 1024:<br />
<br />
print "AC Power Connected 3A Charging"<!-- migrated from Comments; original IP: 73.3.156.187 --></div>73.3.156.187
