<![CDATA[Lcd driver for M5Stack Core2]]>Hi friends, I am looking for the screen driver for the Core 2 for Micropython. It only needs to be a simple driver, the main thing is to display text. Does anyone have a link or even a ready firmware for it?

For the M5Stick C I found a simple driver.
Who has interest in it, can write me.

I had version 1.14 from you at the time
https://github.com/russhughes/ili9342c_mpy

which worked great for me for years on the M5Stack Core2.
But now there is a new version of Core2 version 1.1

Unfortunately, this version no longer runs with your version 1.14.
Is there a way to make the 1.14 version work with the new firmware 1.1?

The differences between Core2 and Core2 v1.1 are as follows:
1.The power management scheme is iterated from Core2(AXP192) to Core2 v1.1(AXP2101+INA3221). The ID of AXP192 and AXP2101 is different, and the program uses this as a sign to distinguish the versions;
2.The power indicator is changed from green to blue;
3.Add RTC chip power supply battery to ensure accurate timing when power is off.

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.

So PowerOff?

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

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?

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?

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

@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

The buttons on the Core2 are actually part of the touchscreen that extend below the display from about Row 240 to 279.

Button press example:

Very simple paint program:

The M5CORE2 firmware.bin has been updated. See the tbbunny.py example from https://github.com/russhughes/ili9342c_mpy/blob/main/examples/M5CORE2/tbbunny.py

I'm not sure why yet.

If I load the SD driver before the screen, the SD does not work.
Something interferes then.

It must be installed before the display driver in any case.

#SD-Card
uos.mount(machine.SDCard(slot=3, sck=18, mosi=23, miso=38, cs=4,), '/sd')
print(uos.listdir('/sd'))

How can you include the internal SD card in your firmware? Do you have any ideas about this?
I have not found anything yet.
