<![CDATA[M5 Fire "get battery level" block]]>Hi
I'm getting started with the M5 Fire and UI Flow
I am trying to print the battery level using the "get battery level" block
I get an awful red ERROR message with "name 'power' isn't defined"
The code is
from m5stack import *
from m5ui import *
from uiflow import *
import time
label0 = M5TextBox(262, 204, "Text", lcd.FONT_Default,0xFFFFFF, rotate=0)
BatLvl = None
while True:
BatLvl = power.getBatteryLevel()
label0.setText(str(BatLvl))
speaker.sing(147, 1)
wait(1)

I thought power was part of the library... If not, what is the correct way of defining it ?

I don't know why but as I tried again and again, it worked...pretty weird...

I tried M5burner on another laptop
It "sees" the M5 fire but cannot flash it
"A fatal error occurred: File fatfs_image_0x370000.bin (length 2678784) at offset 3604480 will not fit in 4194304 bytes of flash. Use --flash-size argument, or change flashing address."
Weird, as the firmware is meant for the fire hardware, it should match its memory size ?!

When i unpack it i has tools folder which include esptool. Copy dll file in this folder. Eventually find downloaded firmware files in firmwares folder and burn it with other flash tools like esp flash tool from espressif home page

Using esptools, where do I need to add python36.dll ?

Is there a way to give it's path to M5burner as a parameter? (I tried adding python36.dll to the Windows PATH, with no luck)
