@TomKatt BTW, I love your Blown Away by Maxell.
The ‘Canvas’ is M5’s name for TFT_eSPI !
Keep up the good work!

@TomKatt Sure, there's lots of us here.

You have to consider the world is on a 24hr cycle.
I would help you but it would not be what you want.
This is TFT_eSPI one of the most famous graphics drivers:
GFX, LVGL, TFT_eSPI .
LOTS of reference and examples.
As I said you have a M5StampS3 which is an ESP32 S3 wth a ST7789V2 LCD, also very common. All small M5Stack products use it. The one from the CardPuter will work in an old StickCPlus.
Here is the Canvas API:
https://docs.m5stack.com/en/arduino/m5gfx/m5gfx_canvas

Have you tried replacing
DinMeter.Display.width() / 2, DinMeter.Display.height() / 2);
with literals, like 50, 50?
Experiment, research, have fun.

@davekc You doubt him at your peril, Sir!

@TomKatt

Cheers!

@TomKatt
This is my "tool drawer"! The browser links I use every day.

@TomKatt The first link is the API
https://docs.m5stack.com/en/arduino/m5dial/display
The other controls are M5GFX or plain-jane GFX
one of thee most common Graphics available.
Look up M5canvas.
The Dial is just a StampS3 and a LCD.

@TomKatt said in M5Stack Arduino IDE Reference (ex Display commands and properties) ?:

M5Dial.Display

@ChuckInDallas Yes.

@ChuckInDallas The Original Core was found to be wearing out it's battery by applications that were powered by USB 24/7.
So the new version Core has a switch on the back to isolate the battery from excessive charging by switching it 'out' of the circuit when not needed.
The red button is the On-Off and reset switch.

@ChuckInDallas Hi!
The bottom plate (with all the GPIO pins) contains the battery.
The back should have a switch marked 1/0.
The switch must be set to 1 and the device powered on by USB.
The device must be ON during this time, I think, for the battery to charge.
Until you feel it is charged, then unplug the USB and see if the charge is maintained.
It only charges this way.

@mgrouch You are so disappointed with M5Stack.

@mgrouch said in Add i2c range extender LTC4311:

AdaFruit and others make a LTC4311 extender but they use qwiic smaller connectors but same pinout.
I2C is designed for sensors close to the controller and 1 - 2 meters is the limit. The LTC4311 gives a little more but after that you should consider RS485.
M5Stack make several of these:
https://docs.m5stack.com/en/unit/rs485
I2C to 485 transceivers.

@felmue Works for me too!
I never thought of that for StickCPlus2 !!!
Thanks

I have a new StickCPlus2 that I want to dim or turn off the display backlight.
The old StickCPlus breathe does not work of course because the power system is very different.
I see that the schematic and the pin map say Output 27 is TFT_BL, but I cannot get either On or Off to turn off the backlight.
What am I doing wrong!!??
Thanks, Terry

@shinshin8 You must ignore that the Arduino IDE reports lilygo boards and select your own Core from the drop down. The IDE is just trying to be helpful, but is always wrong, just ignore it and select the correct board from the drop down list in the little window here:

Also questions:
Are you using this example:
https://github.com/m5stack/M5Unit-ReflectiveIR/blob/main/examples/detect.ino?

Have you tried adjusting the sensitivity trim pot full scale, CW, CCW?

Your hand may not reflect enough IR.

The output is active low, so you should see 0Vdc when a reflective object is in the path. ADC will output 0 digital, Off as well.

@shinshin8 said in M5Stack Reflective IR Sensor Always Reads 0:

Board: LilyGO T-Display (ESP32-D0WDQ6-V3)

What do you mean 'Board: LilyGO T-Display (ESP32-D0WDQ6-V3)'
What version of Arduino IDE are you using?
Are you using this example:
https://github.com/m5stack/M5Unit-ReflectiveIR/blob/main/examples/detect.ino

Later edit:
Is the IR LED turned on?
You can use a phone camera to observe near IR.
Have you tried adjusting the sensitivity trim pot full scale, CW, CCW?
Your hand may not reflect enough IR.
The output is active low, so you should see 0Vdc when a reflective object is in the path. ADC 0Vdc as well.

@Snyder_br
Yes.
