cs = Pin("P3", Pin.OUT_OD) spi = SPI(2, SPI.MASTER, baudrate=115200, polarity=0, phase=1) cs.low() spi.send(b'5') cs.high()
I had the above code to send a SPI message. I am using H7. What is the significance of the first parameter 2 when we call SPI. How do I know what value should be given for this parameter.
Also want to confirm the pin assignment for SPI
P0 (MOSI), P1 (MISO), P2 (SCLK), P3 (SS), Ground
Is there any other pins needed to connect?
