Hey
While those parameters exist on the vanilla micropython (openmv), StickV uses a modified version of micropython (that comes with the firmware) if you need to do you have either 1. work around it (flip image instead of text ) or 2. compile your own firmware and upload it on the stick

btw here are the values you can use on the stickV : https://maixpy.sipeed.com/en/libs/machine_vision/image.html#imagedrawstringx-y-text-color-scale1-xspacing0-yspacing0-monospacetrue

Same problem here.

@hague said in Unreal power discharge / charge current:

I made some tests: The discharge current depends on the Screen Brightness:

idischg: 42mA @ ScreenBreath(7)
idischg: 44mA @ ScreenBreath(8)
idischg: 51mA @ ScreenBreath(9)
idischg: 58mA @ ScreenBreath(10)
idischg: 65mA @ ScreenBreath(11)
idischg: 75mA @ ScreenBreath(12)
idischg: 90mA @ ScreenBreath(13)
idischg: 105mA @ ScreenBreath(14)
idischg: 116mA @ ScreenBreath(15)

The charge current depends on the temperature:

icharge: 86mA @ 31°C
icharge: 86mA @ 44°C
icharge: 8mA @ 46°C
icharge: 8mA @ 48°C
icharge: 8mA @ 52°C

A bright screen is heating up the Stick quite fast.

Hope that helps...

is that 86mA or 8.6mA as thats quite a jump?

BTW thanks for taking the time to do all this testing.

}

@salty_good Is there a calibration yet? Any update?
Thanks

I tested a hub device attached to port A with a few 100cm grove cables and I was able to successfully read the i2c address of the ENV sensor and also others. I tested with the i2c_tester arduino program https://github.com/m5stack/M5Stack/blob/master/examples/Advanced/I2C_Tester/I2C_Tester.ino perhaps its just an isolated incident.

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