esp32

esptool.py --chip esp32 --port /dev/ttyUSBx --baud 1500000 write_flash 0x1000 uiflow-b061698-esp32-4mb-20220304.bin #uiflow-b061698-esp32-spiram-4mb-20220304.bin

esp32c3(STAMP-C3, STAMP-C3U)

esptool.py --chip esp32c3 --port /dev/ttyUSBx --baud 1500000 write_flash 0x0 uiflow-b061698-esp32c3-4mb-20220304.bin

# if you flash the firmware through the USB port, you need press the button A before you plug USB cable enter the download mode
esptool.py --chip esp32c3 --port /dev/ttyUSBx --baud 1500000 write_flash 0x0 uiflow-b061698-esp32c3-usb-4mb-20220304.bin

from the scan result I suspect you are using an M5Core2, correct?

The M5Core2 has an internal (GPIO21/22) and an external (GPIO32/33) I2C bus.

Right now your code scans the internal I2C bus, but the SGP30 is connected to port A (external I2C bus), so you need to change your code to scan the external I2C bus.

Thanks
Felix

from machine import I2C, Pin
i2c = I2C(scl=Pin(22), sda=Pin(21), freq=100000)
i2c.scan()
[52, 53, 56, 81, 104]

I have M5's SGP30 sensor. MicroPython is not detecting anything plugged in. Guidance?

from machine import SoftI2C, Pin
i2c = SoftI2C(sda=machine.Pin(21),scl=machine.Pin(22),freq=100000)
devices = i2c.scan()
devices = [52, 53, 56, 81, 104], the SGP30 should be on 58, right?

Sorry, still under developing, UIFlow 2.0 it's big project, not only the firmware.

>>> import io
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ValueError: incompatible .mpy file

Edit: It helped to delete the io.mpy file under libs/micropython

Look like you've upgraded to 1.18, that's nice, that should speedup some dict loops.

Is there any documentation to the m5 package? Or do you have a changelog or something? Or can yoi upload the sources to github, so that we at can look for ourself for the functions?
