[question] `epd2in13bc` `ReadBusy` check inverted?

[loiccoyle]

Is the busy check for the epd2in13bc inverted?

while(epdconfig.digital_read(self.busy_pin) == 0): # 0: idle, 1: busy

The other displays I've checked look like:

Line 81 in bc23f8e

while(epdconfig.digital_read(self.busy_pin) != 0):

Actually the ReadBusy check for a lot of the displays is inconsistent, is this intentional?
