1 Advanced Use Cases
If you would like to use poweradvantage.py directly from Python instead of Jupyter Notebook we have section 1.1 "poweradvantage.py From Python". If you wish to customize the output format of poweradvantage.py please check section 1.2 "Customized output from poweradvantage.py". If you would like to port to an additional platform, proceed to section 1.3 "Porting poweradvantage.py".1.1 poweradvantage.py from Python
The poweradvantage.py library is accessible directly from Python 3. It can be found at /usr/lib/python<version>/site-packages/poweradvantage.

from poweradvantage import poweradvantage
import time
pa = poweradvantage("VMK180", "SC")
while 1:
pa.printpower()
time.sleep(1) |
1.2 Customized Output from poweradvantage.py
printpower prints the power but can also be copied and modified to make a custom printout.

name = pa.getname()
import numpy as np
data = {'PS_FPD_Power': []}
#create dataframe
df = pd.DataFrame(data)
while 1:
dt_object = datetime.fromtimestamp(datetime.timestamp(datetime.now()))
power = pa.getpower()
for (n, d, p) in zip(pa.name, pa.domain, power):
if (n == 'VCC_PSFP'):
print("PS FPD %7.4f (watts)" % (p[2]))
#append row to the dataframe
new_data = {'PS_FPD_Power': p[2]}
df = df.append(new_data, ignore_index=True)
plt.plot(df.tail(1000)) # plotting by columns
display.clear_output(wait=True)
plt.show() |
1.3 Porting poweradvantage.py
If you wish to support another board type that is not currently supported, poweradvantage.py was coded to be flat and modular.
