M5StickCPlus MicrPython power saving

WonkoTheSane

Hi,
Which MicroPython APIs can help reduce power drain on M5StickCPlus?

I was unable to get basics to work:

lcd.setBrightness(0-100) # didn't change LCD backlight brightnes
power.getBatteryLevel() # didn't seam to work
No API to turn off wifi mentioned at: https://github.com/m5stack/UIFlow-Code/wiki/Advanced - does this work: wifiCfg.wlan_sta.active(False)

Are there other APIs to turn on/off parts of device , or to reduce power drain?

Thanks

@wonkothesane Hi, Usually what you can do is depends on your task to put your ESP32 device into deep sleep mode which will automatically turn off WiFi and other power consuming devices on top of the Stick-C.

Hello @WonkoTheSane

try the following commands:

from m5stack import *
import machine

axp.setLcdBrightness(50) # set LCD backlight brightness
axp.getBatVoltage() # get battery voltage

machine.deepsleep(10000) # deep sleep for 10 seconds
machine.lightsleep(10000) # light sleep for 10 seconds

about WiFi: I don't know how to turn WiFi off with MircoPython, sorry. Somebody else might have an idea?

Cheers

Hi @felmue,
Unfortunately on my M5StickPlus axp.setLcdBrightness(50) gives an error.

Maybe it has different MicroPython hardware APIs than your device?

Hello @WonkoTheSane

Hmm, did you include the line from m5stack import *?

I have UIFlow 1.6.6 firmware installed on my M5StickC Plus and use Blockly's Set screen brightness block then switched to the Python tab.

Thanks
