Usage fault when executing code complied with GCC 10 but not with GCC 7 #16
Description
The following example causes a usage fault when built with GCC 10, but reverting back to GCC 7 fixes the problem. The fault occurs when executing the 2nd delay in loop(), or directly thereafter.
#include < Arduino.h >
#include "Arduino_LED_Matrix.h"
ArduinoLEDMatrix matrix;
void setup() {
Serial.begin(115200);
matrix.begin();
}
const uint32_t happy[] = {
0x19819,
0x80000001,
0x81f8000
};
const uint32_t heart[] = {
0x3184a444,
0x44042081,
0x100a0040
};
void loop(){
matrix.loadFrame(happy);
delay(500);
matrix.loadFrame(heart);
delay(500);
}
