img.resize(240, 135)

There is absent any influence at the image in the screen a lot of parameters of img.draw_string()
F.e. char_rotation, char_vflip, string_rotation, string_hmirror, string_vflip
Is anybody could change this values from the default statement?

Why after sensor.set_hmirror(True) there are change colors?
As a result, there is impossible to use find_blobs by color after hmirror! (

You should use 0,26 pins : Wire.begin(0,26)

There is limited workable G0 pin at M5StickC in the current version of the hardware!
It's could not possible to scan I2C sensor at (0,26) pins
At the same time, there is no problem for (32,33) or (32,26) pins
There was not such a problem in the older version of hardware M2StickC
This problem take place just for some kinds of I2C sensors, f.e. SGP30

@multihelix
Why not, but .. why?? )
It's nothing doing in this sketch )

I'm charging a battery for 2 hrs from off state already and vbat still 3.46V (((

I have received a new m5stick-c from M5Stack Official Store and was shocked by unreal discharge and charge currents
There are 127 mA and 9 mA (from discharging state) in the official example
In my first m5stick-c there were 82 mA and 87 mA
Is anybody have an idea how to improve this terrible situation?!

@ricardocosta
void AXP192::SetSleep(void){

Wire1.beginTransmission(0x34);
Wire1.write(0x31);
Wire1.endTransmission();
Wire1.requestFrom(0x34, 1);
uint8_t buf = Wire1.read();

buf = (1<<3)|buf;
Wire1.beginTransmission(0x34);
Wire1.write(0x31);
Wire1.write(buf);
Wire1.endTransmission();

Wire1.beginTransmission(0x34);
Wire1.write(0x12);
Wire1.write(0x41);
Wire1.endTransmission();

}

@salty_good Could you propose any idea how to calibrate data and get real time angle monitoring sketch?
Because there is a terrible fluctuations from the meaning value in the time.
I could not get something near zero in static position if I do accumulative addition like here:
gyroX += ((float)gX * M5.IMU.gRes - gyroX0);
Where gX - int16_t current gyro value, gyroX0 - float calibration value with gRes, and gyroX - float accumulative angle value

I am already detect that M5.Axp.begin() can help to restore the display

There is display off after M5.Axp.SetSleep()
How to restore (or reset) display from code after that, f.e. when button is pressed?

@salty_good Thank you! I understand
I have not met before the calibration requirements for i2c digital sensors)
Sorry

@salty_good why such values? What does it mean?

Why there are always gyro results the same in any static position of m5stick?

Unfortunately, all these wires were bought in the official m5stack store(
Including 50 cm wire

Oh yes!)
I discovered the cause of this problem with ENV unit
It is long cable (50 cm) to HUB unit
When I connected HUB unit with short cable to m5core - all I2C addresses was scanned successfully!

@playthegame thank you for help!
I updated esp32-arduino with this link - nothing happens
The same result - just 0x68 in I2C scanner listing(

@watson in case of direct connection, ENV unit is working without any problem
