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(
