Stm8L052r8's segment_LCD 1/8 duty inquiry. I need to select Com0,1,2,3, and Com4,5,6,7 by changing the PAGE_COM value of LCD_CR4 register.What should I do if I want to turn on and use the LCD characters of Com0,1,2,3, and Com4,5,6,7 at the same time?

Well, it is not quite clear what you actually want to achieve, so several questions already arise:

  • Should your LCD work in multiplex or statically?
  • Are you aware that the RM0031 mentions 1/8 duty, but the STM8L052 does not support 1/8 duty?
  • Are you also aware that the RM0031 is an RM for a whole group of quite different STM8s and that the STM8L052 has no COM4...COM7?

Regards
