Can anyone suggest what might be causing this error when I try any of the examples shipped with the Microdot Python library:
`pi@raspberrypi:~/Pimoroni/microdotphat/examples $ ./flash.pyTraceback (most recent call last):
File “./flash.py”, line 5, in
from microdotphat import clear, show, set_decimal, set_pixel, WIDTH, HEIGHT
File “/usr/lib/python2.7/dist-packages/microdotphat/init.py”, line 24, in
_n1 = NanoMatrix(address=0x63)

self.bus.write_byte_data(self.address, CMD_MODE, MODE)
IOError: [Errno 5] Input/output error
I also ran i2cdetect which showed no devices detected.
This as running the board on a Pi Zero which has been updated to Pixel. My Scroll Phat runs OK on this Pi.
