I've same display. I've changed in Raspberry Pi pin configuration: RST = 27 DC = 25 LED = 24 in Raspberry Pi pin configuration: RST = 25 DC = 24 LED = 27 ... and now it works


The documentation you link is to the UART. See for the available spidev module documentation. As for the meaning of mode perhaps look at a SPI wiki.


Switch the matrix round. Pull it from the sockets on the circuit board. Turn through 180° and re-insert it. LED matrices have a polarity and it's a common problem to get LEDs lit unexpectedly if the polarity is reversed.
