open M5Burner, if you see comport detected when you connect M5Stick to usb then next step would be to burn CORRECT firmware to it as there are few versions for M5Stick

Problem:

Der Schrittmotor funktioniert nur korrekt in der Z-Achse bei normalen (langsamen) Drehgeschwindigkeiten.
Beim Versuch, die X- und Y-Achsen zu verwenden, funktioniert der Motor nur, wenn ich die Vorschubgeschwindigkeiten auf das 10-fache oder höher erhöhe.
Wenn ich versuche, die Adresse auf 0x71 zu ändern, wird das Modul nicht erkannt.

I had this. Take it apart, disconnect battery, wait a minute or two, plug it back in. Something in the pmic is buggy and this resets it then it works.

M5CoreS3 compatibility with BaseAAA

@HynekT
It should not work. BaseAAA output is only 4V, while CoreS3 requires BUS input of 5V. The input voltage of Core Basic and Core2 is only 3.7V, so it is usable. I suggest using Base DIN for CoreS3.

Using the LoRa868 (old version) w/ Core Basic works as expected w/ precompiled meshtastic firmware. Thanks to @felmue for his hints.

If you want to use precompiled firmware then look into variants.h for the used GPIO and check your Core and LoRa Module whether the IO fits or not.

@johan_s Hi John sorry for the long delay.

I had a chance to play with the frame buffer today after remembering this conversation.

I am finding the issue with the small text/garbidge written to the screen that you shared and looking into it.

Thanks for the point out.

@WigglerAway You will need to check out the documentation on the M5Stack website for the exact pins but by default UART1 is broken out to the blue port and UART 2 is broken out to the MBUS connector.

The CoreMP135 has UART1 broken out to the blue port, UART2 to the MBUS and UART6 broken out to the RS485 connector.

The latest image now has flutter-ui boatinstrument interface on hdmi port.

SignalK is available via web ui. As well as FreeboardSK and KIP dashboard.

After two reboots SD card partition is resized to max available space.

NMEA 2000 interface is ready. All you need to do is connect two wires.

Most of USB gps devices are recognized on plugging in automatically.

Image includes Victron Web UI as well.

Console access is available via USB-C port at
115200 bauds.

Thanks!

@ajb2k3 said in CoreMP135 screen saver sleep for built in LCD:

@mgrouch You need to create a program for that

I do not see how. There are examples for displaying things on ILI9342C
using framebuffer and LVGL.
I do not see how to turn off backlight on ILI9342C. Is there some code example? Or command line utility with the code to control brightness? I was able to code that on m5stack tough on esp32 which has same ILI9342C.

Also how to wake up screen by touch?
I guess with brightness off touch functions are still there. So I need example of code listening for touch event and controlling backlight (voltage of it?) on ILI9342C.

I need some help.
Thanks

Hello @mgrouch

well, you might notice the lowercase b in Gb which means it's 4 Gigabit (not 4 GigaByte). 1 byte equals 8 bits. So you'll need to divide the number by 8 if you want to convert Gigabit to GigaByte.
4'000 Mb / 8 = 500 MB
So about 462 MB (MegaByte) free seems plausible.

Thanks
Felix
