Document display refresh rate #58

Open microbit-carlos opened 6 years ago

microbit-carlos commented 6 years ago

We had this question a few times already, it's hard from the current docs to figure out how often the display is updated.

microbit-sam commented 5 years ago

The display is updated by the MicroBitDisplay systemTick function

I think that means that it updates every 6ms / 166.6 Hz, sound about right?

#define SYSTEM_TICK_PERIOD_MS                   6

No. Each each row is strobed every 6 ms, which means that the display is strobed every 18 ms (55 Hz).

Ah ok, thanks James!
