@ -528,8 +528,8 @@ Some support a few levels of grey or a very small range of colors. They have
long refresh times (many seconds). The principal benefit that they consume zero
current except while being refreshed: it is possible to switch off power
completely with the device retaining the image indefinitely. Present day EPD
units perform the slow refresh autonomously. It makes no demands on the CPU
enabling user code to continue to run.
units perform the slow refresh autonomously - the process makes no demands on
the CPU enabling user code to continue to run.
The drivers are compatible with `uasyncio`. One approach is to use synchronous
methods only and the standard demos (some of which use `uasyncio`) may be run.

The FeatherWing has a reset button which shorts the RST line to Gnd. To avoid
risk of damage to the microcontroller pin if the button is pressed, the pin
