 Bigger Bigger  Smaller Smaller  Reset Reset

im not sure if the datasheet means the HT1632C has internal pullup resistors or you have to add them your self?
Im pretty sure they are internal?

The internal pull up resistors may be there, but they would need to be activated, wouldn't they? (as you activate them for ATmega328)
It doesn't hurt to add physical ones anyway (I always do).
