Hi All - I recently acquired my second microDot pHat, the first behaved exactly as expected.
The more recent pHat behaves, when executing the python code below, as follows:
from microdotphat import clear, show, fill, set_pixel clear() set_pixel(0, 0, 1) show()
from microdotphat import clear, show, fill, set_pixel, write_string, scroll clear() write_string('CCCCCC', kerning=0) show()
I suspect an issue with the first IS31FL3730, but I am not certain - any ideas or experiences would be helpful !
