big function gets inlined making a too big arduino sketch
I would like to revive this issue but submitting another test case.
The attached sketch file has a "move3Servos" function that gets inlined,
causing the sketch size to exceeds the size of the flash (49K with a max size
of 32K)
You can work around the problem adding an attribute noinline
__attribute__((noinline))
void move3Servos(Servo servo1Name, float target_pos1, Servo servo2Name, float
target_pos2, Servo servo3Name, float target_pos3, float easing) {
Doing so reduces the compiled sketch size down to 12K, which is a lot less than
49K
If you're interested in the original discussion, see
