Lcd driver for M5Stack Core2

@russ
Thank you very much for your effort.
What is this code for in the end?
Is it mandatory to use it?

finally:
    # shutdown
    spi.deinit()

The code de initialises the SPI bus so that that other functions can use the pins or the bus

Thanks for the info.
Where is the best place to put it in the code

@wolli01 At the very end of the program before it quits.

I have a problem with the SD card.
My program runs sometimes 1-2 days well through and then when it comes to an error and hangs, it is restarted by the watchdog. When restarting but then no longer the SD card with the command:
sd_device = sdcard.SDCard(spi, cs=Pin(4), baudrate=20000000)
installed.
Do you have a tip what this could be and how I can change it?

@Russ
hello,
when I install the new firmware 1.16, I get the message that the build rate is unknown.
If I go back to 1.14, everything runs without problems.
Do you know what the problem could be?

Is the SD card being filled ?

Wolli01

Yes works perfectly at the beginning.
Sometimes many days without problems and then is no longer written to the SD card.
Sometimes it no longer works after a few hours.

Wolli01

Is there a way to disable the Core2 in software?
So PowerOff?

Wolli01

SD card unfortunately still does not run through!
I get this error message when the SD card fails.
[Errno 5] EIO
I wonder what the problem is here?
Sometimes it goes only 2 hours and sometimes up to 2 days.
If I log nothing on the SD card, I can just write something on it even after 5 days and it goes. Just not in continuous use.
