M5Core2 Power LED

[forstner-m]

Hello,

I have tried this function on the M5Core2:
M5.Power.setLed(0);
M5.Power.setLed(1);
M5.Power.setLed(255);

I tried that too:
auto cfg = M5.config();
cfg.led_brightness = 1;
M5.begin(cfg);

Unfortunately, nothing happens with it. There is no problem with the normal M5Core2 library. Therefore, the LED is not broken.

Am I doing something wrong or is the LED not implented?

Thank you very much!

Best regards,
Michael

Hello, @forstner-m
If the main unit type is Core2 v1.0, you can control the LED, but if it is v1.1, you cannot make detailed adjustments.
This is due to the difference in specifications between AXP192 and AXP2101.

As far as I have checked, it is working in v1.0. What model are you using?

I have a Core2 v1.0 and the led is not switchable. Do you have a code for this function?

As a precaution, please update M5Unified & M5GFX library version to the latest released 0.1.13.

#include <M5Unified.h>

void setup(void)
{
  auto cfg = M5.config();
  cfg.led_brightness = 255;
  M5.begin(cfg);
}

void loop(void)
{
  M5.delay(1000);
  M5.Power.setLed(0);
  M5.delay(1000);
  M5.Power.setLed(255);
}

If this doesn't work, please show me the program you tried that works with M5Core2.h

Your code works, but this do not work:

#include <Arduino.h>
#include <M5GFX.h>
#include <M5Unified.h>

M5GFX display;

void setup(void)
{
auto cfg = M5.config();
cfg.led_brightness = 255;
M5.begin(cfg);
display.begin();
}

void loop(void)
{
while(1)
{
M5.delay(1000);
M5.Power.setLed(0);
M5.delay(1000);
M5.Power.setLed(255);
}
}

If the line "display.begin();" is active the LED is off.

M5Unified includes M5GFX.
M5.Display is an instance of M5GFX.
You must not create your own instances of M5GFX.
Examples of such code are sometimes introduced, but they should be avoided as they can cause problems.

Now it works! Is the line M5.Display.begin(); necessary?
It would still be good if an example were created with canvas. But with this line it works: M5Canvas canvas(&M5.Display);

[lovyan03]

M5.Display.begin() is not required.
This is included in M5.begin().
