Подключили на SPI2 (CS, SCK, MISO, MOSI) = (Y5, Y6, Y7, Y8) = (PB12, PB13, PB14, PB15)

Немного поправил SPI.
self.dc = pyb.Pin(pyb.Pin.cpu.A3, pyb.Pin.OUT, pyb.Pin.PULL_DOWN)
self.reset = pyb.Pin(pyb.Pin.cpu.B10, pyb.Pin.OUT, pyb.Pin.PULL_DOWN)
self.cs = pyb.Pin(pyb.Pin.cpu.A4, pyb.Pin.OUT, pyb.Pin.PULL_DOWN)
spi = SPI(1, SPI.MASTER, baudrate=20000000, polarity=0, phase=0)
