Hello@margel

The description in m5-docs is done with setTextColor.

https://github.com/m5stack/m5-docs/blob/master/docs/en/api/lcd.md
setTextColor( color, backgroundcolor )

Rather, I chose to switch to polling, which worked much better, so it seems.

Way hay I got it.
in micropython you use

i2c.writeto_mem(0x45, 0x00, b'\x01')

to set the mode and then

i2c.writeto_mem(0x45, 0x10, b'\x01') i2c.writeto_mem(0x45, 0x10, b'\x00')

to turn each pin off and on it digital mode.

And I can conform that the EXT I/O 2 and the ExtI/O stamp are the same units!

@teastain I have had a few issues with the SHT30 sensor.
For a start, Hardware I2C is broken in micropython but SoftI2C works fine.
On a core2 I had to use the PaHub to get the SHT30 to read.

I have solved my initial problem in that it was the conversion formula I had wrong.

@rh1972 you need to go to Micropython.org and follow the guides to recompile

Look the information up on the M5Stack web page any search for it

Looks like this ntptime timestamp is relative to 01/01/2000, and not to 01/01/1970 like the Epoch Unix timestamp.

Thanks. Any kind of sound would be great.

My machine module doesn't have the I2S used in this example.
