Power control
|
||
|
|
=============
|
||
|
|
|
||
|
|
:meth:`pyb.wfi` is used to reduce power consumption while waiting for an
|
||
|
|
event such as an interrupt. You would use it in the following situation::
|
||
|
|
|
||
|
|
while True:
|
||
|
|
do_some_processing()
|
||
|
|
pyb.wfi()
|
||
|
|
|
||
|
|
Control the frequency using :meth:`pyb.freq`::
|
||
|
|
|
||
|
|
pyb.freq(30000000) # set CPU frequency to 30MHz
