Hi,
The OLED displayed shown some thing can't understandable, say shown_a=AA; modified the code and shown_b=AB; then modified back to original, and the shown_c should be =AA, but still got AB? why?
Sorry for lack of code, if I can get answer for the "survival memory" is OK.
No code = no idea what you are talking about = no answer possible
Are you talking about non-volatile memory?
Yes, it is called EEPROM.
Thanks.
can the OLED text size be set decimal?
say: display.setTextSize(1.5);
No, it can't
No need to be sorry. Just post it, using code tags when you do

the original set shown well.
int menuitem = 1;
int frame = 1;
int page = 1;
int lastMenuItem = 1;
what I modified shown some thing no good.
int menuitem = 3;
int frame = 2;
int page = 1;
int lastMenuItem = 1;
changed back:
int menuitem = 1;
int frame = 1;
int page = 1;
int lastMenuItem = 1;
still shown no good same as second. why?
I've changed the encoder input pin doesn't work, why?
encoder = new ClickEncoder(8, 9, 10);
