UIFlow 2.0.2 firmware preview version

Zetabyte

Thank you for the update. 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?

Found a bug.

>>> 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

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

Trying to get I2C to work on the new firmware. 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?

@costas softI2c?

Use I2C not softI2c

Costas

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

Hello @Costas

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
