Lcd driver for M5Stack Core2

[Wolli01]

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.

@wolli01 Here is the driver I've been working on https://github.com/russhughes/ili9342c_mpy

@russ Thank You!

@russ
Many, many thanks!
It works perfectly, you saved my project.

[Russ]

@wolli01 Excellent, glad it worked for you.

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

[Wolli01]

Found out now.
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'))

Leider kommen diese Fehlereldungen wenn ich was speichern will. Das lesen geht.
E (39687) sdmmc_cmd: sdmmc_read_sectors_dma: sdmmc_send_cmd returned 0x107
E (39697) sdmmc_cmd: sdmmc_write_sectors_dma: sdmmc_send_cmd returned 0x105

I load the SD driver after the LCD everything goes but the screen is not displayed.
If I load the SD driver before the screen, the SD does not work.
Something interferes then.

I was able to make concurrent display and sdcard work on the original M5Stacks https://github.com/russhughes/TinyBigBuckBunny but have not been able to make it work on the Core2's yet. I'm not sure why yet.

[Russ]

I was able to get simultaneous display and sdcard access working. 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

@russ
Thank you for your work.
It works now.

Hello, is there any way to use the three touch buttons as well?

[Russ]

Yes, I’ll add an example working with the touchscreen later tonight.

[Wolli01]

@russ
Super!
Thank you for doing this work.

[Russ]

@wolli01 Updated repo with two examples using the touchscreen. 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:

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()

    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
