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.
