This is because the CPU clock, running at 168 MHz, is divided by -2 and then by prescaler+1, giving a freqency of 168 MHz/2/(83+1)=1 MHz +2 and then by prescaler+1, giving a frequency of 168 MHz/2/(83+1)=1 MHz for timer 2. The period is set to a large number so that the timer can count up to a large number before wrapping back around to zero. In this case it will take about 17 minutes before it cycles back to diff --git a/docs/pyboard/tutorial/usb_mouse.rst b/docs/pyboard/tutorial/usb_mouse.rst index 4c3a85e548..ac1de6e275 100644 --- a/docs/pyboard/tutorial/usb_mouse.rst +++ b/docs/pyboard/tutorial/usb_mouse.rst @@ -61,7 +61,7 @@ The first argument to the function ``osc`` is the number of mouse events to send and the second argument is the delay (in milliseconds) between events.

In safe mode, the ``boot.py`` and ``main.py`` files are not executed, and so the pyboard boots up with default settings.
