hello,
i purchased https://shop.mikroe.com/serial-7-seg-display-2-board - as it's using max7219 i did not expect any issue. yet.. the examples do do not really work.
i wired it like this (espruino pico):
cs = b14
sck = b13
mosi = b15
gnd = gnd
vcc = 3.3v
can someone please advise if there's something that can prevent from the configuration to work? currently the display seem to be either on and off, or flashes randomly.
thank you!
jose
