i found a sketch that work,
tomorrow i check your library compared to this sketch.
i post the link, so it may help other person
if we understand the difference may update your library and Officially insert the ST7032i support
p.s. in your comment in the library you write that the display xxx.xxxx 3V3, means a 3,3V diplay.
This is not correct. All the diplay that you mention are 3V, the other "3" means 3V led backlight
3V= 3V lcd no backlight
3V3= 3V lcd with 3(fV) led backlight
