Description
When compiling an Arduino project that uses the Matter library (v3.1.0) together with M5Unified (v0.2.2) on M5Stack Atom, I encounter a compilation error caused by an ambiguous reference to attribute_t. It appears that the Matter library defines attribute_t in esp_matter_core.h, and M5Unified (via M5GFX) also declares attribute_t as an enum in enum.hpp.
Sketch
#include <M5Unified.h>
#include <Matter.h>
void setup() {
M5.begin();
Matter.begin();
// ...
}
void loop() {
M5.update();
// ...
}Debug Message
