Thank you Felix.

Hello @jhubsch

on M5Core2 LCD brightness is controlled by AXP192 (as you've already figured out yourself) so changing LCD brightness should work with:

M5.Axp.SetLcdVoltage(v); // v from 2500 to 3300

Thanks
Felix

@nlindin This one works!

#include <M5Core2.h>
#include <IRremote.h>

IRrecv irrecv(35);
decode_results ircode;

void setup() {
M5.begin();
irrecv.enableIRIn();
}

void loop()
{
if (irrecv.decode(&ircode))
{
Serial.println(ircode.value, HEX);
delay(100);
irrecv.resume();
}
m5.update();
}

Maybe it would be an idea to use an I2C to 1-Wire converter? Like the DS2482-100. Then you can have several I2C devices on the bus and also 1-Wire devices. I have not tried the chip yet. But I will do that soon.

Hi!
Board settings==board info?

Whit "M5Stack-Core-Esp32"> M5Stack Arduino> M5Stack-Core2 works nice to me.

@ajb2k3 thanks for your answer but as you can see just above I already got the answer from another post on the forum.
In fact this is not that simple.
Yes you can flash the device with the binaries found on the MicroPython website but then you only get the basic lib to get access to the ESP32.
If you want to take advantage of all 'surrounding' features like touch screen, accelerometer etc...then, unlike with UIFlow where the libs do encapsulate all those surrounding features, you have to dig yourself and find the correct libs as M5Stack is not providing one.

Thank you!

Hello @Zontex

Understood. Thank you for checking.

Maybe it could still be wired to a GPIO, but via a solder bridge, so it could be used optionally?

Anyways, I've soldered a wire from AXP IRQ to ESP32 GPIO35. I can detect now when USB (aka ACIN) has been connected or disconnected while ESP32 is in light sleep and use that to wake up.

Cheers

Hello @jimbo_s

you're welcome. I am glad you got it working to your liking.

Happy Stacking!
Felix

Hi @Zontex

No offence, but I went ahead and created my own M5GO in white with some additional modifications, actually mostly removing stuff which consumes too much power for my battery operated project. I've called it M5PogoBottom.

Cheers
Felix

yee i have the same problem.

Hello @m5stack

I can imagine you guys are busy with all the new exiting products (M5CoreInk, M5Paper etc.), but I was wondering about when Rop's excellent improvements for M5Core2 will be approved?

BTW: I am using Rop's code for a while now and with great success.

Thank you very much in advance.

Hello @revta

thank you for sharing your experience.

Re ATECC608A: I did not notice the link in the M5Core2 documentation until now.

However running an I2C scanner on M5Core2 doesn't reveal such a device (which by default should have address 0x35). All devices the scanner detects are: 0x34 (AXP), 0x38 (Touch), 0x51 (RTC) and 0x68 (IMU).

The 8 pin IC close to USB-C you referring to I think is part of the protection circuit for the SD card - but I could be wrong about that.

At this point my conclusion is that the ATEC608A never made it into the final design.

Happy Stacking!
Felix

that did it
THANK you

@felmue Wow thank you for all the information
