ATOM S3 Lite: M5.Led API not available / UIFlow LED control not working

[YoshihiroSato]

Environment

• Hardware: ATOM S3 Lite
• Library: M5Unified latest version (as of YYYY/MM/DD)
• Development: Arduino IDE / UIFlow

Issue Summary

Using the M5.Led API on the ATOM S3 Lite causes a compilation error. In UIFlow, the LED control block exists but the LED does not respond.

Steps to Reproduce

1. Include the following code in a sample sketch:
   M5.Led.setRGB(255,0,0);
2. Compile the sketch. The following error occurs:
   class m5::M5Unified' has no member named 'Led
3. In UIFlow, placing the LED control block has no effect.

Additional Information

• The G35 LED on AtomS3 Lite works correctly when controlled directly via NeoPixel.

• M5.Led exists and works on AtomS3 (with LCD) and AtomS3 Pro, suggesting this is specific to the Lite version.

Expected Behavior

M5.Led API or the UIFlow LED block should properly control the LED on AtomS3 Lite.

Hello, @YoshihiroSato

Currently, M5Unified does not support RGB LEDs.
Therefore, the M5Unified sample code does not include anything that handles M5.Led.
Perhaps you have tried sample code from another library ?

Hello @lovyan03,

Thank you for your quick response. I understand that M5Unified currently does not support RGB LEDs.

I also want to express my appreciation—your work with LovyanGFX has been incredibly helpful, and thanks to it, I’ve been able to develop many projects.

Best regards,
Yoshihiro Sato
