No, it's one of the main reasons why those who would like to run bare metal MicroPython are instead forced to use the bloated UIflow firmware, which has the relative unexposed 'lcd' driver within it in module 'm5stack'.
Over a year and still waiting for independent MicroPython versions of such modules ...
Is it possible that lcd.image expects an image smaller than the lcd? Perhaps it needs to be resized.
Have you tried displaying a small image?
+1 for Thonny, works great. Only drawback is that it does not yet have debug functionality for MicroPython.
Related to this request would be having the possibility of burning bare MicroPython from source, bringing in all M5Core drivers, and adding any user made apps, tables and pre-cooked code.
Ok, so after 10 days we have:
I'd be interested to hear from more people. M5Stack, do you have an idea of the distribution of operating systems for the community at large?
A good mix so far, interesting. Feel free to add your own, oh silent reader ;-)
I'll start. I use
2 = MicroPython
OK it works. So for future reference this is what I did:
From now on whenever you turn it on the Stick will run boot.py and then main.py in the /flash directory.
If when it's so running you attach the device to a computer via the USB cable, you can interrupt whatever it is doing by starting Thonny and hitting ctrl-F2 (Stop/Restart Backend), which will bring up the MicroPython REPL prompt. Cool.
I am curious about software platform usage in M5Stack devices, so here is my poll, just reply with the number that applies to you:
The figures on each line are the number of posts shown for each in the forum today.
Thanks for participating

Excellent, I will try that, thank you very much.
@erich re: your other question
For MicroPython I use Thonny, it's bare bone but does the trick. Have a look at this to get started.

I would ideally like to load a bare metal MicroPython firmware with the M5stack libraries tagged on - but since the latter bit of code is not forthcoming (:( I have resorted to using the standard UIFlow 1.6.6 firmware and:
Except that what I would really like to do is just turn on the Stick and have it run my.py automatically, independently of Thonny or any computers. How can I do that?
You'd think someone else would have had a similar question but I have searched far and wide for variations on the title of this post to no avail.
Thanks,
Jack
Thanks @felmue and @robalstona , I will try your suggestions tomorrow.
Jack
I measure quantities and display them every tenth of a second or so. The screen flickers annoyingly.
I have tried lcd.clear() and overwriting with the previous text with lcd.Black color in between writes but they both flicker the same way. printing '\r' on each line before writing text doesn't work either.
Other suggestions?
Yes, @ajb2k3, it was you I was looking for! :-)
Now 1.6.5 is there in my original download, so I guess we don't have to download a new M5 burner any time there is a new release, thank you.
I should mention that M5Burner says that Base Micropython is v1.11 while os.uname() says it is in fact v1.12
Jack
Hello, helloo, helooo... Is there anybody out there!?! Cue Pink Floyd :-)
I don't see it in the M5burner I downloaded a couple of weeks ago. Do we have to download M5burner again every time there is a new version?
Excellent, thank you very much Felix. And nice informative site you have there!
May I ask how you ensure that MPU6886 is off in MicroPython?
Hi, I would like to use the GPIO 25 and 26 pins in the header for I2C, so I am setting them up as follows in MicroPython:
from machine import Pin, I2C
i2c = I2C(1, scl=Pin(26), sda=Pin(25), freq=400000)
However, the description says that "G36/G25 share the same port, when one of the pins is used, the other pin should be set as a floating input" and provides the following example
For example, to use the G36 pin as the ADC input, Configuration the G25 pin as FLOATING
setup()
{
M5.begin();
pinMode(36, INPUT);
gpio_pulldown_dis(GPIO_NUM_25);
gpio_pullup_dis(GPIO_NUM_25);
}
It seems that I should set GPIO36 to Floating. How does one do this in MicroPython, and where could one find such settings in the documentation? I have looked for a couple of hours and can't find this anywhere.

PS How do you create a code window on this board?
