característica:
- Você pode definir a largura e a altura da trilha elipse
- O ângulo de rotação da trilha elipse pode ser definido e o estado horizontal do texto do menu pode ser corrigido automaticamente
- Você pode definir o passo móvel das coordenadas da trajetória de movimento
- Você pode definir a faixa de movimento para alterar a frequência
- Pode ser configurado para girar no sentido horário ou anti-horário
- Você pode definir se o botão de movimento interrompe o botão de movimento circular
